WIMS> Overview and Diagram of Counter MIB v0.40






Hi Ron and others,                              Sunday (5 December 2004)

Here are a simple overview and structure diagram for Counter MIB v0.40.

Cheers,
- Ira

[overview]


(1) Before reading any version of the Counter MIB, you must be familiar
    with the PWG Counter spec that Pete Zehler is writing:

        ftp://ftp.pwg.org/pub/pwg/wims/wd/wd-wimscount10-20041102.pdf

(2) When complete, the PWG Counter MIB will make _normative_ reference
    to the PWG Counter spec for the behavior of counters and the
    relationships between counters.

(3) The Counter MIB v0.40 supports monitoring of all the Service types
    and Availability/Monitoring/Work/MediaUsed counters defined in the
    Counter spec, plus UP3i features (e.g., Lifetime/PowerOn/Reset).

(4) The Counter MIB v0.40 supports monitoring of all the Subunit types
    defined in the Printer MIB (RFC 1759/3805) and PWG Subunits schema
    (work-in-progress).

(5) The 'icKeyTable' in Counter MIB v0.40 supports inverted lookups and
    is analogous to the 'jmJobIDTable' in the Job Mon MIB (RFC 2707).

(6) The 'icKeyTable' supports system allocation of an abstract key for
    each pair of 'icServiceType' and 'icServiceIndex' for a Service or
    'icSubunitType' and 'icSubunitIndex' for a Subunit.
    (This abstract key allows both Services and Subunits to _share_
    the common Availability/Monitoring/Work/MediaUsed counter tables,
    which would otherwise be impossible.)

(7) The 'icServiceTable' in Counter MIB v0.40 supports _direct_ lookup
    of the abstract key for each configured Service type and instance
    (a requirement from Xerox and Sharp contributors).

(8) The 'icSubunitTable' in Counter MIB v0.40 supports _direct_ lookup
    of the abstract key for each configured Subunit type and instance.

(9) The 'icMediaUsedTable' in Counter MIB v0.40 is now subordinate to
    the individual Services/Subunits (consistent with Counter spec).
