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

2. MFPA IOC 10/24/1999PWG Job Monitoring MIB2 Why do I need a Job Monitoring MIB ? n Many printers can accept multiple jobs n Many printers support multiple job submission protocols (IPP, LPD, port9100, Apple PAP, Pserver,...) n 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

3. MFPA IOC 10/24/1999PWG Job Monitoring MIB3 Problem Statement n 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 n Independent of the job submission protocol

4. MFPA IOC 10/24/1999PWG Job Monitoring MIB4 Job Monitoring MIB Requirements n 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

5. MFPA IOC 10/24/1999PWG Job Monitoring MIB5 Why use SNMP ? n SNMP is a mature protocol. n The Printer MIB (RFC 1759) is widely implemented. n SNMP is commonly used for vendor independent management/printing systems. n SNMP currently implemented in most networked printer controllers. n SNMP provides a single way to monitor many job submission protocols

13. MFPA IOC 10/24/1999PWG Job Monitoring MIB13 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)

14. MFPA IOC 10/24/1999PWG Job Monitoring MIB14 Job ID Group n 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

15. MFPA IOC 10/24/1999PWG Job Monitoring MIB15 Job Group n 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

16. MFPA IOC 10/24/1999PWG Job Monitoring MIB16 Job Attribute Group n OPTIONAL job info n 71 attributes defined so far n 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

24. MFPA IOC 10/24/1999PWG Job Monitoring MIB24 Job Submission Protocol Mapping to Job Monitoring MIB n Title: Job Submission Protocol Mapping Recommendations for the Job Monitoring MIB, Feb 1999 n Maps LPR/LPD, AppleTalk, IPP, IPDS, DPA, NDPS, PJL, PostScript, Pserver, Nprinter, and TIP/SI job submision protocols to the PWG Job MIB

25. MFPA IOC 10/24/1999PWG Job Monitoring MIB25 Current Status n 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 n We believe that they mean the attribute structure? n Planning an interoperability bakeoff in 2000 – IBM, Hitachi Koki, and Xerox
