PWG Job Monitoring MIB 2

Why do I need a Job Monitoring MIB ?

Many printers can accept multiple jobs Many printers support multiple job

submission protocols (IPP, LPD, port9100, Apple PAP, Pserver, ...)

Users and operators wants to know:– status of pending, processing, completed jobs– print instructions (attributes) on specific jobs– detailed page level monitoring of current job

MFPA IOC 10/24/1999


Problem Statement

Need for monitoring print jobs in devices and servers– status of print jobs– progress of print jobs– accounting data: resources used during and at

job completion Independent of the job submission protocol

MFPA IOC 10/24/1999


Job Monitoring MIB Requirements Types of users:

– end-user - submitted job (via some protocol)– system operator - manages printers– capacity planner - how busy are printers– accountant - how to charge for usage

MFPA IOC 10/24/1999


Why use SNMP ?

SNMP is a mature protocol. The Printer MIB (RFC 1759) is widely

implemented. SNMP is commonly used for vendor independent

management/printing systems. SNMP currently implemented in most networked

printer controllers. SNMP provides a single way to monitor many job

submission protocols

General Group

– Job Set Index - so can have more than one set– Number of Active Jobs - not completed or held– Oldest Active Index - can skip over completed– Newest Active Index - can get newest active– Job Persistence - time job in ‘completed’ state– Attribute Persistence - time attributes in

‘completed’ state– Job Set Name - user friendly name for this job set

(name of queue or device)

MFPA IOC 10/24/1999


Job ID Group

Maps client generated ID (string) to Job Set Index and Job Index for fast client access to a job– Job Submission ID - client generated job ID. – Associated Job Set index for job– Associated Job Index in its Job set for job

MFPA IOC 10/24/1999


Job Group

MIB objects for each job:– Job Index - 32-bit index of job in table (same as IPP “job-id” or

LPD job id)– Job State - one of 7 states– Job State Reasons 1 - 32 bits of extra sub-state information– Number of Intervening Jobs - queue position– K Octets Per Copy Requested - size of job– K Octets Processed - progress monitor– Impressions Per Copy Requested - number of impressions– Impressions Completed - progress monitor– Job Owner - string name of job submitter

MFPA IOC 10/24/1999


Job Attribute Group

OPTIONAL job info 71 attributes defined so far More can be easily registered

– Attribute Type - enum identifies which attribute– Attribute Instance Index - so job can have multiple

values of an attribute, e.g., media names used– Value As Integer - integer form of value– Value as Octets - octet string form of value

Job Submission Protocol Mapping to Job Monitoring MIB Title: “Job Submission Protocol Mapping

Recommendations for the Job Monitoring MIB”, Feb 1999

Maps LPR/LPD, AppleTalk, IPP, IPDS, DPA, NDPS, PJL, PostScript, Pserver, Nprinter, and TIP/SI job submision protocols to the PWG Job MIB

MFPA IOC 10/24/1999


Current Status

The PWG Job Monitoring MIB and Job Submission Protocol Mapping drafts:– Approved by IESG as an Informational RFC– Waiting for the RFC Editor to publish– not standards track– IETF warning: MIB structure not recommended

We believe that they mean the attribute structure?

Planning an interoperability bakeoff in 2000– IBM, Hitachi Koki, and Xerox
