IESG Note
This MIB module uses an unconventional scheme for modeling management
information (on top of the SNMP model) which is unique to this MIB.
The IESG recommends against using this document as an example for the
design of future MIBs.
The "Printer Working Group" industry consortium is not an IETF
working group, and the IETF does not recognize the Printer Working
Group as a standards-setting body. This document is being published
solely to provide information to the Internet community regarding a
MIB that might be deployed in the marketplace. Publication of this
document as an RFCis not an endorsement of this MIB.
Abstract
This document provides a printer industry standard SNMP MIB for (1)
monitoring the status and progress of print jobs (2) oBTaining
resource requirements before a job is processed, (3) monitoring
resource consumption while a job is being processed and (4)
collecting resource accounting data after the completion of a job.
This MIB is intended to be implemented (1) in a printer or (2) in a
server that supports one or more printers. Use of the object set is
not limited to printing. However, support for services other than
printing is outside the scope of this Job Monitoring MIB. Future
extensions to this MIB may include, but are not limited to, fax
machines and scanners.

1 Introduction
This specification defines an official Printer Working Group (PWG)
[PWG] standard SNMP MIB for the monitoring of jobs on network
printers. This specification is being published as an IETF
Information Document for the convenience of the Internet community.
In consultation with the IETF Application Area Directors, it was
concluded that this MIB specification properly belongs as an
Information document, because this MIB monitors a service node on the
network, rather than a network node proper.
The Job Monitoring MIB is intended to be implemented by an agent
within a printer or the first server closest to the printer, where
the printer is either directly connected to the server only or the
printer does not contain the job monitoring MIB agent. It is
recommended that implementations place the SNMP agent as close as
possible to the processing of the print job. This MIB applies to
printers with and without spooling capabilities. This MIB is
designed to be compatible with most current commonly-used job
submission protocols. In most environments that support high
function job submission/job control protocols, like ISO DPA [iso-
dpa], those protocols would be used to monitor and manage print jobs
rather than using the Job Monitoring MIB.
The Job Monitoring MIB consists of a General Group, a Job Submission
ID Group, a Job Group, and an Attribute Group. Each group is a
table. All Accessible objects are read-only. The General Group
contains general information that applies to all jobs in a job set.
The Job Submission ID table maps the job submission ID that the
client uses to identify a job to the jmJobIndex that the Job
Monitoring Agent uses to identify jobs in the Job and Attribute
tables. The Job table contains the MANDATORY integer job state and
status objects. The Attribute table consists of multiple entries per
job that specify (1) job and document identification and parameters,
(2) requested resources, and (3) consumed resources during and after
job processing/printing. A larger number of job attributes are
defined as textual conventions that an agent SHALL return if the
server or device implements the functionality so represented and the
agent has access to the information.
1.1 Types of Information in the MIB
The job MIB is intended to provide the following information for the
indicated Role Models in the Printer MIB [print-mib] (Appendix D -
Roles of Users).
User:
Provide the ability to identify the least busy printer. The
user will be able to determine the number and size of jobs
waiting for each printer. No attempt is made to actually
predict the length of time that jobs will take.
Provide the ability to identify the current status of the
user"s job (user queries).
Provide a timely indication that the job has completed and
where it can be found.
Provide error and diagnostic information for jobs that did not
successfully complete.
Operator:
Provide a presentation of the state of all the jobs in the
print system.
Provide the ability to identify the user that submitted the
print job.
Provide the ability to identify the resources required by each
job.
Provide the ability to define which physical printers are
candidates for the print job.
Provide some idea of how long each job will take. However,
exact estimates of time to process a job is not being
attempted. Instead, objects are included that allow the
operator to be able to make gross estimates.
Capacity Planner:
Provide the ability to determine printer utilization as a
function of time.
Provide the ability to determine how long jobs wait before
starting to print.
Accountant:
Provide information to allow the creation of a record of
resources consumed and printer usage data for charging users or
groups for resources consumed.
Provide information to allow the prediction of consumable usage
and resource need.
The MIB supports printers that can contain more than one job at a
time, but still be usable for low end printers that only contain a
single job at a time. In particular, the MIB supports the needs of
Windows and other PC environments for managing low-end direct-connect
(serial or parallel) and networked devices without unnecessary
overhead or complexity, while also providing for higher end systems
and devices.
1.2 Types of Job Monitoring Applications
The Job Monitoring MIB is designed for the following types of
monitoring applications:
1. Monitor a single job starting when the job is submitted and
ending a defined period after the job completes. The Job
Submission ID table provides the map to find the specific job
to be monitored.
2. Monitor all "active" jobs in a queue, which this
specification generalizes to a "job set". End users may use
such a program when selecting a least busy printer, so the
MIB is designed for such a program to start up quickly and
find the information needed quickly without having to read
all (completed) jobs in order to find the active jobs.
System operators may also use such a program, in which case
it would be running for a long period of time and may also be
interested in the jobs that have completed. Finally such a
program may be used to provide an enhanced console and
logging capability.
3. Collect resource usage for accounting or system utilization
purposes that copy the completed job statistics to an
accounting system. It is recognized that depending on
accounting programs to copy MIB data during the job-retention
period is somewhat unreliable, since the accounting program
may not be running (or may have crashed). Such a program is
also eXPected to keep a shadow copy of the entire Job
Attribute table including completed, canceled, and aborted
jobs which the program updates on each polling cycle. Such a
program polls at the rate of the persistence of the Attribute
table. The design is not optimized to help such an
application determine which jobs are completed, canceled, or
aborted. Instead, the application SHOULD query each job that
the application"s shadow copy shows was not complete,
canceled, or aborted at the previous poll cycle to see if it
is now complete or canceled, plus any new jobs that have been
submitted.
The MIB provides a set of objects that represent a compatible subset
of job and document attributes of the ISO DPA standard [iso-dpa] and
the Internet Printing Protocol (IPP) [ipp-model], so that coherence
is maintained between these two protocols and the information
presented to end users and system operators by monitoring
applications. However, the job monitoring MIB is intended to be used
with printers that implement other job submitting and management
protocols, such as IEEE 1284.1 (TIPSI) [tipsi], as well as with ones
that do implement ISO DPA. Thus the job monitoring MIB does not
require implementation of either the ISO DPA or IPP protocols.
The MIB is designed so that an additional MIB(s) can be specified in
the future for monitoring multi-function (scan, FAX, copy) jobs as an
augmentation to this MIB.
2 Terminology and Job Model
This section defines the terms that are used in this specification
and the general model for jobs in alphabetical order.
NOTE - Existing systems use conflicting terms, so these terms are
drawn from the ISO 10175 Document Printing Application (DPA)
standard [iso-dpa]. For example, PostScript systems use the term
session for what is called a job in this specification and the
term job to mean what is called a document in this specification.
Accounting Application: The SNMP management application that copies
job information to some more permanent medium so that another
application can perform accounting on the data for Accountants, Asset
Managers, and Capacity Planners use.
Agent: The network entity that accepts SNMP requests from a monitor
or accounting application and provides access to the instrumentation
for managing jobs modeled by the management objects defined in the
Job Monitoring MIB module for a server or a device.
Attribute: A name, value-pair that specifies a job or document
instruction, a status, or a condition of a job or a document that has
been submitted to a server or device. A particular attribute NEED
NOT be present in each job instance. In other Words, attributes are
present in a job instance only when there is a need to express the
value, either because (1) the client supplied a value in the job
submission protocol, (2) the document data contained an embedded
attribute, or (3) the server or device supplied a default value. An
agent MAY represent an attribute as an entry (row) in the Attribute
table in this MIB in which entries are present only when necessary.
Attributes are identified in this MIB by an enum.
Client: The network entity that end users use to submit jobs to
spoolers, servers, or printers and other devices, depending on the
configuration, using any job submission protocol over a serial or
parallel port to a directly-connected device or over the network to a
networked-connected device.
Device: A hardware entity that (1) interfaces to humans, such as a
device that produces marks on paper or scans marks on paper to
produce an electronic representation, (2) accesses digital media,
such as CD-ROMs, or (3) interfaces electronically to another device,
such as sends FAX data to another FAX device.
Document: A sub-section within a job that contains print data and
document instructions that apply to just the document.
Document Instruction: An instruction specifying how to process the
document. Document instructions MAY be passed in the job submission
protocol separate from the actual document data, or MAY be embedded
in the document data or a combination, depending on the job
submission protocol and implementation.
End User: A user that uses a client to submit a print job. See
"user".
Impression: For a print job, an impression is the passage of the
entire side of a sheet by the marker, whether or not any marks are
made and independent of the number of passes that the side makes past
the marker. Thus a four pass color process counts as a single
impression, as does highlight color. Impression counters count all
kinds: monochrome, highlight color, and full process color, while
full color counters only count full color impressions, and high light
color counters only count high light color impressions.
One-sided processing involves one impression per sheet. Two-sided
processing involves two impressions per sheet. If a two-sided
document has an odd number of pages, the last sheet still counts as
two impressions, if that sheet makes two passes through the marker or
the marker marks on both sides of a sheet in a single pass. Two-up
printing is the placement of two logical pages on one side of a sheet
and so is still a single impression. See "page" and "sheet".
NOTE - Since impressions include blank sides, it is suggested that
accounting application implementers consider charging for sheets,
rather than impressions, possibly using the value of the sides
attribute to select different charges for one-sided versus two-sided
printing, since some users may think that impressions don"t include
blank sides.
Internal Collation: The production of the sheets for each document
copy performed within the printing device by making multiple passes
over either the source or an intermediate representation of the
document.
Job: A unit of work whose results are expected together without
interjection of unrelated results. A job contains one or more
documents.
Job Accounting: The activity of a management application of
accessing the MIB and recording what happens to the job during and
after the processing of the job.
Job Instruction: An instruction specifying how, when, or where the
job is to be processed. Job instructions MAY be passed in the job
submission protocol or MAY be embedded in the document data or a
combination depending on the job submission protocol and
implementation.
Job Monitoring (using SNMP): The activity of a management
application of accessing the MIB and (1) identifying jobs in the job
tables being processed by the server, printer or other devices, and
(2) displaying information to the user about the processing of the
job.
Job Monitoring Application: The SNMP management application that End
Users, and System Operators use to monitor jobs using SNMP. A
monitor MAY be either a separate application or MAY be part of the
client that also submits jobs. See "monitor".
Job Set: A group of jobs that are queued and scheduled together
according to a specified scheduling algorithm for a specified device
or set of devices. For implementations that embed the SNMP agent in
the device, the MIB job set normally represents all the jobs known to
the device, so that the implementation only implements a single job
set. If the SNMP agent is implemented in a server that controls one
or more devices, each MIB job set represents a job queue for (1) a
specific device or (2) set of devices, if the server uses a single
queue to load balance between several devices. Each job set is
disjoint; no job SHALL be represented in more than one MIB job set.
Monitor: Short for Job Monitoring Application.
Page: A page is a logical division of the original source document.
Number up is the imposition of more than one page on a single side of
a sheet. See "impression" and "sheet" and "two-up".
Proxy: An agent that acts as a concentrator for one or more other
agents by accepting SNMP operations on the behalf of one or more
other agents, forwarding them on to those other agents, gathering
responses from those other agents and returning them to the original
requesting monitor.
Queuing: The act of a device or server of ordering (queuing) the
jobs for the purposes of scheduling the jobs to be processed.
Printer: A device that puts marks on media.
Server: A network entity that accepts jobs from clients and in turn
submits the jobs to printers and other devices that may be directly
connected to the server via a serial or parallel port or may be on
the network. A server MAY be a printer supervisor control program,
or a print spooler.
Sheet: A sheet is a single instance of a medium, whether printing on
one or both sides of the medium. See "impression" and "page".
SNMP Information Object: A name, value-pair that specifies an
action, a status, or a condition in an SNMP MIB. Objects are
identified in SNMP by an OBJECT IDENTIFIER.
Spooler: A server that accepts jobs, spools the data, and decides
when and on which printer to print the job. A spooler is a client to
a printer or a printer supervisor, depending on implementation.
Spooling: The act of a device or server of (1) accepting jobs and
(2) writing the job"s attributes and document data on to secondary
storage.
Stacked: When a media sheet is placed in an output bin of a device.
Supervisor: A server that contains a control program that controls a
printer or other device. A supervisor is a client to the printer or
other device.
System Operator: A user that uses a monitor to monitor the system
and carries out tasks to keep the system running.
System Administrator: A user that specifies policy for the system.
Two-up: The placement of two pages on one side of a sheet so that
each side or impressions counts as two pages. See "page" and
"sheet".
User: A person that uses a client or a monitor. See "end user".
2.1 System Configurations for the Job Monitoring MIB
This section enumerates the three configurations in which the Job
Monitoring MIB is intended to be used. To simplify the pictures, the
devices are shown as printers. See section 1.1 entitled "Types of
Information in the MIB".
The diagram in the Printer MIB [print-mib] entitled: "One Printer"s
View of the Network" is assumed for this MIB as well. Please refer
to that diagram to aid in understanding the following system
configurations.
2.1.1 Configuration 1 - client-printer
In the client-printer configuration 1, the client(s) submit jobs
directly to the printer, either by some direct connect, or by network
connection.
The job submitting client and/or monitoring application monitor jobs
by communicating directly with an agent that is part of the printer.
The agent in the printer SHALL keep the job in the Job Monitoring MIB
as long as the job is in the printer, plus a defined time period
after the job enters the completed state in which accounting programs
can copy out the accounting data from the Job Monitoring MIB.

Figure 2-1 - Configuration 1 - client-printer - agent in the printer
The Job Monitoring MIB is designed to support the following
relationships (not shown in Figure 2-1):
1. Multiple clients MAY submit jobs to a printer.
2. Multiple clients MAY monitor a printer.
3. Multiple monitors MAY monitor a printer.
4. A client MAY submit jobs to multiple printers.
5. A monitor MAY monitor multiple printers.
2.1.2 Configuration 2 - client-server-printer - agent in the server
In the client-server-printer configuration 2, the client(s) submit
jobs to an intermediate server by some network connection, not
directly to the printer. While configuration 2 is included, the
design center for this MIB is configurations 1 and 3.
The job submitting client and/or monitoring application monitor jobs
by communicating directly with:
A Job Monitoring MIB agent that is part of the server (or a front
for the server)
There is no SNMP Job Monitoring MIB agent in the printer in
configuration 2, at least that the client or monitor are aware. In
this configuration, the agent SHALL return the current values of the
objects in the Job Monitoring MIB both for jobs the server keeps and
jobs that the server has submitted to the printer. The Job
Monitoring MIB agent obtains the required information from the
printer by a method that is beyond the scope of this document. The
agent in the server SHALL keep the job in the Job Monitoring MIB in
the server as long as the job is in the printer, plus a defined time
period after the job enters the completed state in which accounting
programs can copy out the accounting data from the Job Monitoring
MIB.

The Job Monitoring MIB is designed to support the following
relationships (not shown in Figure 2-2):
1. Multiple clients MAY submit jobs to a server.
2. Multiple clients MAY monitor a server.
3. Multiple monitors MAY monitor a server.
4. A client MAY submit jobs to multiple servers.
5. A monitor MAY monitor multiple servers.
6. Multiple servers MAY submit jobs to a printer.
7. Multiple servers MAY control a printer.
2.1.3 Configuration 3 - client-server-printer - client monitors printer
agent and server
In the client-server-printer configuration 3, the client(s) submit
jobs to an intermediate server by some network connection, not
directly to the printer. That server does not contain a Job
Monitoring MIB agent.
The job submitting client and/or monitoring application monitor jobs
by communicating directly with:
1. The server using some undefined protocol to monitor jobs in
the server (that does not contain the Job Monitoring MIB) AND
2. A Job Monitoring MIB agent that is part of the printer to
monitor jobs after the server passes the jobs to the printer.
In such configurations, the server deletes its copy of the
job from the server after submitting the job to the printer
usually almost immediately (before the job does much
processing, if any).
In configuration 3, the agent (in the printer) SHALL keep the values
of the objects in the Job Monitoring MIB that the agent implements
updated for a job that the server has submitted to the printer. The
agent SHALL obtain information about the jobs submitted to the
printer from the server (either in the job submission protocol, in
the document data, or by direct query of the server), in order to
populate some of the objects the Job Monitoring MIB in the printer.
The agent in the printer SHALL keep the job in the Job Monitoring MIB
as long as the job is in the Printer, and longer in order to
implement the completed state in which monitoring programs can copy
out the accounting data from the Job Monitoring MIB.

3 Managed Object Usage
This section describes the usage of the objects in the MIB.
3.1 Conformance Considerations
In order to achieve interoperability between job monitoring
applications and job monitoring agents, this specification includes
the conformance requirements for both monitoring applications and
agents.
3.1.1 Conformance Terminology
This specification uses the verbs: "SHALL", "SHOULD", "MAY", and
"NEED NOT" to specify conformance requirements according to RFC2119
[RFC2119] as follows:
"SHALL": indicates an action that the subject of the sentence
must implement in order to claim conformance to this specification
"MAY": indicates an action that the subject of the sentence does
not have to implement in order to claim conformance to this
specification, in other words that action is an implementation
option
"NEED NOT": indicates an action that the subject of the sentence
does not have to implement in order to claim conformance to this
specification. The verb "NEED NOT" is used instead of "may not",
since "may not" sounds like a prohibition.
"SHOULD": indicates an action that is recommended for the subject
of the sentence to implement, but is not required, in order to
claim conformance to this specification.
3.1.2 Agent Conformance Requirements
A conforming agent:
1. SHALL implement all MANDATORY groups in this specification.
2. SHALL implement any attributes if (1) the server or device
supports the functionality represented by the attribute and (2)
the information is available to the agent.
3. SHOULD implement both forms of an attribute if it implements an
attribute that permits a choice of INTEGER and OCTET STRING
forms, since implementing both forms may help management
applications by giving them a choice of representations, since
the representation are equivalent. See the JmAttributeTypeTC
textual-convention.
NOTE - This MIB, like the Printer MIB, is written following the
subset of SMIv2 that can be supported by SMIv1 and SNMPv1
implementations.
3.1.2.1 MIB II System Group objects
The Job Monitoring MIB agent SHALL implement all objects in the
System Group of MIB-II [mib-II], whether the Printer MIB [print-mib]
is implemented or not.
3.1.2.2 MIB II Interface Group objects
The Job Monitoring MIB agent SHALL implement all objects in the
Interfaces Group of MIB-II [mib-II], whether the Printer MIB [print-
mib] is implemented or not.
3.1.2.3 Printer MIB objects
If the agent is providing access to a device that is a printer, the
agent SHALL implement all of the MANDATORY objects in the Printer MIB
[print-mib] and all the objects in other MIBs that conformance to the
Printer MIB requires, such as the Host Resources MIB [hr-mib]. If
the agent is providing access to a server that controls one or more
direct-connect or networked printers, the agent NEED NOT implement
the Printer MIB and NEED NOT implement the Host Resources MIB.
3.1.3 Job Monitoring Application Conformance Requirements
A conforming job monitoring application:
1. SHALL accept the full syntactic range for all objects in all
MANDATORY groups and all MANDATORY attributes that are
required to be implemented by an agent according to Section
3.1.2 and SHALL either present them to the user or ignore
them.
2. SHALL accept the full syntactic range for all attributes,
including enum and bit values specified in this specification
and additional ones that may be registered with the PWG and
SHALL either present them to the user or ignore them. In
particular, a conforming job monitoring application SHALL not
malfunction when receiving any standard or registered enum or
bit values. See Section 3.7 entitled "IANA and PWG
Registration Considerations".
3. SHALL NOT fail when operating with agents that materialize
attributes after the job has been submitted, as opposed to
when the job is submitted.
4. SHALL, if it supports a time attribute, accept either form of
the time attribute, since agents are free to implement either
time form.
3.2 The Job Tables and the Oldest Active and Newest Active Indexes
The jmJobTable and jmAttributeTable contain objects and attributes,
respectively, for each job in a job set. These first two indexes
are:
1. jmGeneralJobSetIndex - which job set
2. jmJobIndex - which job in the job set
In order for a monitoring application to quickly find that active
jobs (jobs in the pending, processing, or processingStopped states),
the MIB contains two indexes:
1. jmGeneralOldestActiveJobIndex - the index of the active job
that has been in the tables the longest.
2. jmGeneralNewestActiveJobIndex - the index of the active job
that has been most recently added to the tables.
The agent SHALL assign the next incremental value of jmJobIndex to
the job, when a new job is accepted by the server or device to which
the agent is providing access. If the incremented value of
jmJobIndex would exceed the implementation-defined maximum value for
jmJobIndex, the agent SHALL "wrap" back to 1. An agent uses the
resulting value of jmJobIndex for storing information in the
jmJobTable and the jmAttributeTable about the job.
It is recommended that the largest value for jmJobIndex be much
larger than the maximum number of jobs that the implementation can
contain at a single time, so as to minimize the premature re-use of a
jmJobIndex value for a newer job while clients retain the same "
stale" value for an older job.
It is recommended that agents that are providing access to
servers/devices that already allocate job-identifiers for jobs as
integers use the same integer value for the jmJobIndex. Then
management applications using this MIB and applications using other
protocols will see the same job identifiers for the same jobs.
Agents providing access to systems that contain jobs with a job
identifier of 0 SHALL map the job identifier value 0 to a jmJobIndex
value that is one higher than the highest job identifier value that
any job can have on that system. Then only job 0 will have a
different job-identifier value than the job"s jmJobIndex value.
NOTE - If a server or device accepts jobs using multiple job
submission protocols, it may be difficult for the agent to meet the
recommendation to use the job-identifier values that the server or
device assigns as the jmJobIndex value, unless the server/device
assigns job-identifiers for each of its job submission protocols from
the same job-identifier number space.
Each time a new job is accepted by the server or device that the
agent is providing access to AND that job is to be "active" (pending,
processing, or processingStopped, but not pendingHeld), the agent
SHALL copy the value of the job"s jmJobIndex to the
jmGeneralNewestActiveJobIndex object. If the new job is to be "
inactive" (pendingHeld state), the agent SHALL not change the value
of jmGeneralNewestActiveJobIndex object (though the agent SHALL
assign the next incremental jmJobIndex value to the job).
When a job transitions from one of the "active" job states (pending,
processing, processingStopped) to one of the "inactive" job states
(pendingHeld, completed, canceled, or aborted), with a jmJobIndex
value that matches the jmGeneralOldestActiveJobIndex object, the
agent SHALL advance (or wrap) the value to the next oldest "active"
job, if any. See the JmJobStateTC textual-convention for a
definition of the job states.
Whenever a job transitions from one of the "inactive" job states to
one of the "active" job states (from pendingHeld to pending or
processing), the agent SHALL update the value of either the
jmGeneralOldestActiveJobIndex or the jmGeneralNewestActiveJobIndex
objects, or both, if the job"s jmJobIndex value is outside the range
between jmGeneralOldestActiveJobIndex and
jmGeneralNewestActiveJobIndex.
When all jobs become "inactive", i.e., enter the pendingHeld,
completed, canceled, or aborted states, the agent SHALL set the value
of both the jmGeneralOldestActiveJobIndex and
jmGeneralNewestActiveJobIndex objects to 0.
NOTE - Applications that wish to efficiently access all of the active
jobs MAY use jmGeneralOldestActiveJobIndex value to start with the
oldest active job and continue until they reach the index value equal
to jmGeneralNewestActiveJobIndex, skipping over any pendingHeld,
completed, canceled, or aborted jobs that might intervene.
If an application detects that the jmGeneralNewestActiveJobIndex is
smaller than jmGeneralOldestActiveJobIndex, the job index has
wrapped. In this case, the application SHALL reset the index to 1
when the end of the table is reached and continue the GetNext
operations to find the rest of the active jobs.
NOTE - Applications detect the end of the jmAttributeTable table when
the OID returned by the GetNext operation is an OID in a different
MIB. There is no object in this MIB that specifies the maximum value
for the jmJobIndex supported by the implementation.
When the server or device is power-cycled, the agent SHALL remember
the next jmJobIndex value to be assigned, so that new jobs are not
assigned the same jmJobIndex as recent jobs before the power cycle.
3.3 The Attribute Mechanism and the Attribute Table(s)
Attributes are similar to information objects, except that attributes
are identified by an enum, instead of an OID, so that attributes may
be registered without requiring a new MIB. Also an implementation
that does not have the functionality represented by the attribute can
omit the attribute entirely, rather than having to return a
distinguished value. The agent is free to materialize an attribute
in the jmAttributeTable as soon as the agent is aware of the value of
the attribute.
The agent materializes job attributes in a four-indexed
jmAttributeTable:
1. jmGeneralJobSetIndex - which job set
2. jmJobIndex - which job in the job set
3. jmAttributeTypeIndex - which attribute
4. jmAttributeInstanceIndex - which attribute instance for those
attributes that can have multiple values per job.
Some attributes represent information about a job, such as a file-
name, a document-name, a submission-time or a completion time. Other
attributes represent resources required, e.g., a medium or a
colorant, etc. to process the job before the job starts processing OR
to indicate the amount of the resource consumed during and after
processing, e.g., pages completed or impressions completed. If both
a required and a consumed value of a resource is needed, this
specification assigns two separate attribute enums in the textual
convention.
NOTE - The table of contents lists all the attributes in order. This
order is the order of enum assignments which is the order that the
SNMP GetNext operation returns attributes. Most attributes apply to
all three configurations covered by this MIB specification (see
section 2.1 entitled "System Configurations for the Job Monitoring
MIB"). Those attributes that apply to a particular configuration are
indicated as "Configuration n:" and SHALL NOT be used with other
configurations.
3.3.1 Conformance of Attribute Implementation
An agent SHALL implement any attribute if (1) the server or device
supports the functionality represented by the attribute and (2) the
information is available to the agent. The agent MAY create the
attribute row in the jmAttributeTable when the information is
available or MAY create the row earlier with the designated "unknown"
value appropriate for that attribute. See next section.
If the server or device does not implement or does not provide access
to the information about an attribute, the agent SHOULD NOT create
the corresponding row in the jmAttributeTable.
3.3.2 Useful, "Unknown", and "Other" Values for Objects and Attributes
Some attributes have a "useful" Integer32 value, some have a "useful"
OCTET STRING value, some MAY have either or both depending on
implementation, and some MUST have both. See the JmAttributeTypeTC
textual convention for the specification of each attribute.
SNMP requires that if an object cannot be implemented because its
values cannot be accessed, then a compliant agent SHALL return an
SNMP error in SNMPv1 or an exception value in SNMPv2. However, this
MIB has been designed so that "all" objects can and SHALL be
implemented by an agent, so that neither the SNMPv1 error nor the
SNMPv2 exception value SHALL be generated by the agent. This MIB has
also been designed so that when an agent materializes an attribute,
the agent SHALL materialize a row consisting of both the
jmAttributeValueAsInteger and jmAttributeValueAsOctets objects.
In general, values for objects and attributes have been chosen so
that a management application will be able to determine whether a "
useful", "unknown", or "other" value is available. When a useful
value is not available for an object, that agent SHALL return a
zero-length string for octet strings, the value "unknown(2)" for
enums, a "0" value for an object that represents an index in another
table, and a value "-2" for counting integers.
Since each attribute is represented by a row consisting of both the
jmAttributeValueAsInteger and jmAttributeValueAsOctets MANDATORY
objects, SNMP requires that the agent SHALL always create an
attribute row with both objects specified. However, for most
attributes the agent SHALL return a "useful" value for one of the
objects and SHALL return the "other" value for the other object. For
integer only attributes, the agent SHALL always return a zero-length
string value for the jmAttributeValueAsOctets object. For octet
string only attributes, the agent SHALL always return a "-1" value
for the jmAttributeValueAsInteger object.
3.3.3 Index Value Attributes
A number of attributes are indexes in other tables. Such attribute
names end with the word "Index". If the agent has not (yet) assigned
an index value for a particular index attribute for a job, the agent
SHALL either: (1) return the value 0 or (2) not add this attribute to
the jmAttributeTable until the index value is assigned. In the
interests of brevity, the semantics for 0 is specified once here and
is not repeated for each index attribute specification and a DEFVAL
of 0 is implied, even though the DEFVAL for jmAttributeValueAsInteger
is -2.
3.3.4 Data Sub-types and Attribute Naming Conventions
Many attributes are sub-typed to give a more specific data type than
Integer32 or OCTET STRING. The data sub-type of each attribute is
indicated on the first line(s) of the description. Some attributes
have several different data sub-type representations. When an
attribute has both an Integer32 data sub-type and an OCTET STRING
data sub-type, the attribute can be represented in a single row in
the jmAttributeTable. In this case, the data sub-type name is not
included as the last part of the name of the attribute, e.g.,
documentFormat(38) which is both an enum and/or a name. When the
data sub-types cannot be represented by a single row in the
jmAttributeTable, each such representation is considered a separate
attribute and is assigned a separate name and enum value. For these
attributes, the name of the data sub-type is the last part of the
name of the attribute: Name, Index, DateAndTime, TimeStamp, etc. For
example, documentFormatIndex(37) is an index.
NOTE: The Table of Contents also lists the data sub-type and/or data
sub-types of each attribute, using the textual-convention name when
such is defined. The following abbreviations are used in the Table
of Contents as shown:
"Int32(-2..)" Integer32 (-2..2147483647)
"Int32(0..)" Integer32 (0..2147483647)
"Int32(1..)" Integer32 (1..2147483647)
"Int32(m..n)" For all other Integer ranges, the lower
and upper bound of the range is
indicated.
"UTF8String63" JmUTF8StringTC (SIZE(0..63))
"JobString63" JmJobStringTC (SIZE(0..63))
"Octets63" OCTET STRING (SIZE(0..63))
"Octets(m..n)" For all other OCTET STRING ranges, the
exact range is indicated.
3.3.5 Single-Value (Row) Versus Multi-Value (MULTI-ROW) Attributes
Most attributes have only one row per job. However, a few attributes
can have multiple values per job or even per document, where each
value is a separate row in the jmAttributeTable. Unless indicated
with "MULTI-ROW:" in the JmAttributeTypeTC description, an agent
SHALL ensure that each attribute occurs only once in the
jmAttributeTable for a job. Most of the "MULTI-ROW" attributes do
not allow duplicate values, i.e., the agent SHALL ensure that each
value occurs only once for a job. Only if the specification of the "
MULTI-ROW" attribute also says "There is no restriction on the same
xxx occurring in multiple rows" can the agent allow duplicate values
to occur for the job.
NOTE - Duplicates are allowed for "extensive" "MULTI-ROW" attributes,
such as fileName(34) or documentName(35) which are specified to be "
per-document" attributes, but are not allowed for "intensive" "
MULTI-ROW" attributes, such as mediumConsumed(171) and
documentFormat(38) which are specified to be "per-job" attributes.
3.3.6 Requested Objects and Attributes
A number of objects and attributes record requirements for the job.
Such object and attribute names end with the word "Requested". In
the interests of brevity, the phrase "requested" means: (1) requested
by the client (or intervening server) in the job submission protocol
and may also mean (2) embedded in the submitted document data, and/or
(3) defaulted by the recipient device or server with the same
semantics as if the requester had supplied, depending on
implementation. Also if a value is supplied by the job submission
client, and the server/device determines a better value, through
processing or other means, the agent MAY return that better value for
such object and attribute.
3.3.7 Consumption Attributes
A number of objects and attributes record consumption. Such
attribute names end with the word "Completed" or "Consumed". If the
job has not yet consumed what that resource is metering, the agent
either: (1) SHALL return the value 0 or (2) SHALL not add this
attribute to the jmAttributeTable until the consumption begins. In
the interests of brevity, the semantics for 0 is specified once here
and is not repeated for each consumption attribute specification and
a DEFVAL of 0 is implied, even though the DEFVAL for
jmAttributeValueAsInteger is -2.
3.3.8 Attribute Specifications
This section specifies the job attributes.
In the following definitions of the attributes, each description
indicates whether the useful value of the attribute SHALL be
represented using the jmAttributeValueAsInteger or the
jmAttributeValueAsOctets objects by the initial tag: "INTEGER:" or "
OCTETS:", respectively.
Some attributes allow the agent implementer a choice of useful values
of either an integer, an octet string representation, or both,
depending on implementation. These attributes are indicated with "
INTEGER:" AND/OR "OCTETS:" tags.
A very few attributes require both objects at the same time to
represent a pair of useful values (see mediumConsumed(171)). These
attributes are indicated with "INTEGER:" AND "OCTETS:" tags. See the
jmAttributeGroup for the descriptions of these two MANDATORY objects.
NOTE - The enum assignments are grouped logically with values
assigned in groups of 20, so that additional values may be registered
in the future and assigned a value that is part of their logical
grouping.
Values in the range 2**30 to 2**31-1 are reserved for private or
experimental usage. This range corresponds to the same range
reserved in IPP. Implementers are warned that use of such values may
conflict with other implementations. Implementers are encouraged to
request registration of enum values following the procedures in
Section 3.7.1.
NOTE: No attribute name exceeds 31 characters.
The standard attribute types are:
jmAttributeTypeIndex Datatype
-------------------- --------
other(1), Integer32 (-2..2147483647)
AND/OR
OCTET STRING(SIZE(0..63))
INTEGER: and/or OCTETS: An attribute that is not in the
list and/or that has not been approved and registered with
the PWG.
+++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++
+ Job State attributes (3 - 19 decimal)
+
+ The following attributes specify the state of a job.
+++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++
jobStateReasons2(3), JmJobStateReasons2TC
INTEGER: Additional information about the job"s current state
that augments the jmJobState object. See the description under
the JmJobStateReasons1TC textual-convention.
jobStateReasons3(4), JmJobStateReasons3TC
INTEGER: Additional information about the job"s current state
that augments the jmJobState object. See the description under
JmJobStateReasons1TC textual-convention.
jobStateReasons4(5), JmJobStateReasons4TC
INTEGER: Additional information about the job"s current state
that augments the jmJobState object. See the description under
JmJobStateReasons1TC textual-convention.
processingMessage(6), JmUTF8StringTC (SIZE(0..63))
OCTETS: MULTI-ROW: A coded character set message that is
generated by the server or device during the processing of the
job as a simple form of processing log to show progress and any
problems. The natural language of each value is specified by
the corresponding processingMessageNaturalLangTag(7) value.
NOTE - This attribute is intended for such conditions as
interpreter messages, rather than being the printable form of
the jmJobState and jmJobStateReasons1 objects and
jobStateReasons2, jobStateReasons3, and jobStateReasons4
attributes. In order to produce a localized printable form of
these job state objects/attribute, a management application
SHOULD produce a message from their enum and bit values.
NOTE - There is no job description attribute in IPP/1.0 that
corresponds to this attribute and this attribute does not
correspond to the IPP/1.0 "job-state-message" job description
attribute, which is just a printable form of the IPP "job-state"
and "job-state-reasons" job attributes.
There is no restriction for the same message occurring in
multiple rows.
processingMessageNaturalLangTag(7), OCTET STRING(SIZE(0..63))
OCTETS: MULTI-ROW: The natural language of the corresponding
processingMessage(6) attribute value. See section 3.6.1,
entitled "Text generated by the server or device".
If the agent does not know the natural language of the job
processing message, the agent SHALL either (1) return a zero
length string value for the processingMessageNaturalLangTag(7)
attribute or (2) not return the
processingMessageNaturalLangTag(7) attribute for the job.
There is no restriction for the same tag occurring in multiple
rows, since when this attribute is implemented, it SHOULD have a
value row for each corresponding processingMessage(6) attribute
value row.
jobCodedCharSet(8), CodedCharSet
INTEGER: The MIBenum identifier of the coded character set that
the agent is using to represent coded character set objects and
attributes of type "JmJobStringTC". These coded character set
objects and attributes are either: (1) supplied by the job
submitting client or (2) defaulted by the server or device when
omitted by the job submitting client. The agent SHALL represent
these objects and attributes in the MIB either (1) in the coded
character set as they were submitted or (2) MAY convert the
coded character set to another coded character set or encoding
scheme as identified by the jobCodedCharSet(8) attribute. See
section 3.6.2, entitled "Text supplied by the job submitter".
These MIBenum values are assigned by IANA [IANA-charsets] when
the coded character sets are registered. The coded character
set SHALL be one of the ones registered with IANA [IANA] and the
enum value uses the CodedCharSet textual-convention from the
Printer MIB. See the JmJobStringTC textual-convention.
If the agent does not know what coded character set was used by
the job submitting client, the agent SHALL either (1) return the
"unknown(2)" value for the jobCodedCharSet(8) attribute or (2)
not return the jobCodedCharSet(8) attribute for the job.
jobNaturalLanguageTag(9), OCTET STRING(SIZE(0..63))
OCTETS: The natural language of the job attributes supplied by
the job submitter or defaulted by the server or device for the
job, i.e., all objects and attributes represented by the "
JmJobStringTC" textual-convention, such as jobName,
mediumRequested, etc. See Section 3.6.2, entitled "Text
supplied by the job submitter".
If the agent does not know what natural language was used by the
job submitting client, the agent SHALL either (1) return a zero
length string value for the jobNaturalLanguageTag(9) attribute
or (2) not return jobNaturalLanguageTag(9) attribute for the
job.
+++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++
+ Job Identification attributes (20 - 49 decimal)
+
+ The following attributes help an end user, a system
+ operator, or an accounting program identify a job.
+++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++
jobURI(20), OCTET STRING(SIZE(0..63))
OCTETS: MULTI-ROW: The job"s Universal Resource
Identifier (URI) [RFC1738]. See IPP [ipp-model] for
example usage.
NOTE - The agent may be able to generate this value on each
SNMP Get operation from smaller values, rather than having
to store the entire URI.
If the URI exceeds 63 octets, the agent SHALL use multiple
values, with the next 63 octets coming in the second value,
etc.
NOTE - IPP [ipp-model] has a 1023-octet maximum length for
a URI, though the URI standard itself and HTTP/1.1 specify
no maximum length.
jobAccountName(21), OCTET STRING(SIZE(0..63))
OCTETS: Arbitrary binary information which MAY be coded
character set data or encrypted data supplied by the
submitting user for use by accounting services to allocate
or categorize charges for services provided, such as a
customer account name or number.
NOTE: This attribute NEED NOT be printable characters.
serverAssignedJobName(22), JmJobStringTC (SIZE(0..63))
OCTETS: Configuration 3 only: The human readable string
name, number, or ID of the job as assigned by the server
that submitted the job to the device that the agent is
providing access to with this MIB.
NOTE - This attribute is intended for enabling a user to
find his/her job that a server submitted to a device when
either the client does not support the jmJobSubmissionID or
the server does not pass the jmJobSubmissionID through to
the device.
jobName(23), JmJobStringTC (SIZE(0..63))
OCTETS: The human readable string name of the job as
assigned by the submitting user to help the user
distinguish between his/her various jobs. This name does
not need to be unique.
This attribute is intended for enabling a user or the
user"s application to convey a job name that MAY be printed
on a start sheet, returned in a query result, or used in
notification or logging messages.
In order to assist users to find their jobs for job
submission protocols that don"t supply a jmJobSubmissionID,
the agent SHOULD maintain the jobName attribute for the
time specified by the jmGeneralJobPersistence object,
rather than the (shorter) jmGeneralAttributePersistence
object.
If this attribute is not specified when the job is
submitted, no job name is assumed, but implementation
specific defaults are allowed, such as the value of the
documentName attribute of the first document in the job or
the fileName attribute of the first document in the job.
The jobName attribute is distinguished from the jobComment
attribute, in that the jobName attribute is intended to
permit the submitting user to distinguish between different
jobs that he/she has submitted. The jobComment attribute
is intended to be free form additional information that a
user might wish to use to communicate with himself/herself,
such as a reminder of what to do with the results or to
indicate a different set of input parameters were tried in
several different job submissions.
jobServiceTypes(24), JmJobServiceTypesTC
INTEGER: Specifies the type(s) of service to which the job
has been submitted (print, fax, scan, etc.). The service
type is bit encoded with each job service type so that more
general and arbitrary services can be created, such as
services with more than one destination type, or ones with
only a source or only a destination. For example, a job
service might scan, faxOut, and print a single job. In
this case, three bits would be set in the jobServiceTypes
attribute, corresponding to the hexadecimal values: 0x8 +
0x20 + 0x4, respectively, yielding: 0x2C.
Whether this attribute is set from a job attribute supplied
by the job submission client or is set by the recipient job
submission server or device depends on the job submission
protocol. This attribute SHALL be implemented if the
server or device has other types in addition to or instead
of printing.
One of the purposes of this attribute is to permit a
requester to filter out jobs that are not of interest. For
example, a printer operator may only be interested in jobs
that include printing.
jobSourceChannelIndex(25), Integer32 (0..2147483647)
INTEGER: The index of the row in the associated Printer
MIB [print-mib] of the channel which is the source of the
print job.
jobSourcePlatformType(26), JmJobSourcePlatformTypeTC
INTEGER: The source platform type of the immediate
upstream submitter that submitted the job to the server
(configuration 2) or device (configuration 1 and 3) to
which the agent is providing access. For configuration 1,
this is the type of the client that submitted the job to
the device; for configuration 2, this is the type of the
client that submitted the job to the server; and for
configuration 3, this is the type of the server that
submitted the job to the device.
submittingServerName(27), JmJobStringTC (SIZE(0..63))
OCTETS: For configuration 3 only: The administrative name
of the server that submitted the job to the device.
submittingApplicationName(28), JmJobStringTC (SIZE(0..63))
OCTETS: The name of the client application (not the server
in configuration 3) that submitted the job to the server or
device.
jobOriginatinGhost(29), JmJobStringTC (SIZE(0..63))
OCTETS: The name of the client host (not the server host
name in configuration 3) that submitted the job to the
server or device.
deviceNameRequested(30), JmJobStringTC (SIZE(0..63))
OCTETS: The administratively defined coded character set
name of the target device requested by the submitting user.
For configuration 1, its value corresponds to the Printer
MIB [print-mib]: prtGeneralPrinterName object. For
configuration 2 and 3, its value is the name of the logical
or physical device that the user supplied to indicate to
the server on which device(s) they wanted the job to be
processed.
queueNameRequested(31), JmJobStringTC (SIZE(0..63))
OCTETS: The administratively defined coded character set
name of the target queue requested by the submitting user.
For configuration 1, its value corresponds to the queue in
the device for which the agent is providing access. For
configuration 2 and 3, its value is the name of the queue
that the user supplied to indicate to the server on which
device(s) they wanted the job to be processed.
NOTE - typically an implementation SHOULD support either
the deviceNameRequested or queueNameRequested attribute,
but not both.
physicalDevice(32), hrDeviceIndex
AND/OR
JmUTF8StringTC (SIZE(0..63))
INTEGER: MULTI-ROW: The index of the physical device MIB
instance requested/used, such as the Printer MIB [print-mib].
This value is an hrDeviceIndex value. See the Host
Resources MIB [hr-mib].
AND/OR
OCTETS: MULTI-ROW: The name of the physical device to
which the job is assigned.
numberOfDocume
