  1. PWG Job Monitoring MIB Overview Integrated Office Conference ‘99 Status of Management Technologies SNMP MIBs, DMTF, and WEB-basedEnterprise Management

  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 PWG Job Monitoring MIB

  3. 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 PWG Job Monitoring MIB

  4. 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 PWG Job Monitoring MIB

  5. 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 PWG Job Monitoring MIB

  13. 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) PWG Job Monitoring MIB

  14. 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 PWG Job Monitoring MIB

  15. 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 PWG Job Monitoring MIB

  16. 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 PWG Job Monitoring MIB

  17. Job State attributes • jobStateReasons2 • jobStateReasons3 • jobStateReasons4 • processingMessage • processingMessageNaturalLangTag • jobCodedCharSet • jobNaturalLanguageTag PWG Job Monitoring MIB

  18. Identification using Attributes • Device Name • Device Vendor Name • Device Model Name • Device Version • Device Serial number PWG Job Monitoring MIB

  24. 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 PWG Job Monitoring MIB

  25. 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 PWG Job Monitoring MIB

  26. For Further Information • The PWG Job Monitoring MIB draft is at: • ftp://ftp.ietf.org/rfc-drafts/ • draft-ietf-printmib-job-monitor-08.txt • The Job Submission Protocol Mappingdraft is at: • ftp://ftp.ietf.org/rfc-drafts/ • draft-ietf-printmib-job-protomap-03.txt PWG Job Monitoring MIB
