- AGENDA
-
-
- o Administrivia
- - Attendance list, someone to write minutes
- o Review of Charter
- - Objectives, goals of each document
- o Document 1: FINAL REVIEW (again!)
- - Behind Timeframe objectives
- - WILL submit to RFC process on 22 Feb. (Thursday)
- - DRAFT with minor revisions will be posted to mailing list for
- final comments THIS MONDAY. Comments will be accepted through
- 20 Feb.
- - Revisions to date: primarily syntax, semantics from the
- draft.01. Major change was moving examples from the statement
- of problem to an appendix.
- - My questions: Agreement on logged alert is ASN.1 OCTET STRING?
- No implication as to contents, and the goal is to avoid the
- dreaded OPAQUE. String might or might not be a construct (mine
- aren't right now :-). Since SNMP says primitives, we would be
- treating the OCTET STRING like an OPAQUE; the guy asking for it
- has to know it's intern format. Failure to reach closure TODAY
- means I will mak it a CHOICE of the two.
- o OPEN FOR QUESTIONS AND COMMENTS ON DRAFT 1, but ...
- - Protocol implementers are encouraged to voice concerns on
- specific deviations from SNMP/CMOT specs
- - Document syntax, layout is still fair game
- - Document goals have been agreed on for over 6 months, and are
- no longer a topic for debate (closure was reached).
- - Criticisms of mechanisms must be backed up with implementations
- (eg. I tried this, and it cost too much, didn't work, etc).
-
-
- MINUTES
-
- Meeting opened with Lou discussing the two documents that the WG is
- chartered with writing. The first deals with mechanisms that systems
- should use to control the flow of alert information. It is being
- authored by Lou. The second, written by John Cook, details specific
- techniques that an implementer of alerts may wish to consider. Its
- focus is on how alerts are generated.
-
- Final Review of document 1
-
- Logged alerts should be of the SMI type OPAQUE.
-
- Lou was hesitant to use this, as OPAQUES use has been avoided. However,

-
-
-
- the SNMP constraint of not using construct ASN.1 types ruled out the
- option of encapsulating an SNMP trap in an OCTET STRING. The use of a
- simple OCTET STRING would be a violation of ASN.1, and would not result
- in further parsing of the trap.
-
- A review of the DRAFT event and logging tutorial by the OIM Working
- Group followed. Lou agreed to contact Lee LaBarre about resolving any
- potential conflicts with the alert logging. The only problem centered
- on the Alert-Man requirement that a full log wrap. OIM shows this
- wrapping behavior as optional; halting behavior must be supported. The
- Alert-Man requirements might be presented as a subset of the OSI logging
- function. No problems were found with the OIM view of feedback/pin.
-
- The latest set of changes to the DRAFT will be posted on the 11th of
- this month. Comments will be accepted through the 22nd. At that time,
- the DRAFT will be submitted to the RFC process, as a protocol standard.
- Its initial, requested status will be elective.
-
- 2nd Document
-
- Lou will again post his sample technique/format to the mailing list. He
- also agreed to write a short overview of CMOT events that Brian will
- review for the second document. John discussed the format and status of
- the second document. Implementation reviews are being solicited for the
- following techniques:
-
- o threshold hysteresis (time and value based)
- o snapshots
- o thresholds on exceptions
- o thresholds built on counters, gauges, tidemarks
- o sliding window "pins" on each threshold
- o adaptive thresholds
-
- We are also looking for any other techniques in use. Submissions should
- represent actual implementations (can be in-house code), and can be
- posted to the working group list in the format Lou is using.
-
- John will post the DRAFT in its current state shortly.
