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 RFC is 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.
Bergman, et al. Informational [Page 4]
RFC 2707 Job Monitoring MIB - V1.0 November 1999
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.
