- RFC1404 Deployment Experience
-
- Daniel Karrenberg reported that the efforts to convert MONSTER to use
- RFC1404 have not progressed. Due to resource constraints further
- development of MONSTER has been put on indefinite hold. What would be
- needed to make it use RFC1404 is just a relatively simple reformatter.
- Further it could need a rewrite of the actual SNMP polling function
- since this uses the snmp capable awk from ISODE which is very hard to
- install. Daniel renewed his offer to get started, those people who are
- interested in continuing work on Monster.
-
- Craig Haney who was not present at the Working Group meeting has a PERL
- parser for the RFC1404 format.
-
- A list of problems were reported with RFC1404:
-
-
- o In the syntax for device-fields multiple tag-tables are not
- delimited syntactically. Proposed solutions:
-
- - Count preceding
- - Different field separator withing tag-table
- - Bracketing tag-table with something BEGIN-TAGT, END-TAGT
- - Bracketing with
-
-
- The Group decided to use s around tag-table. This will lead to a
- revision of the BNF:
-
-
- device-section ::= "BEGIN_DEVICE" <FS>
- <device-field> <FS>
- "END_DEVICE"
-
- device-field ::= <networkname><FS><routername><FS><linkname><FS>
- <bw-value><FS><bw-sort><FS><proto-type><FS>
- <proto-addr><FS><time-zone><FS> "{" <tag-table> "}"
-
- 1
-
-
-
-
-
- [ "{" <tag-table> "}" ]
-
-
- Action: Bernhard volunteered to check for similar problems and report
- via mail.
-
- After the discussion the Group decided to collect more problem reports
- from implementors before trying to issue another RFC.
-
- There IS interest in USING tools following the RFC out there. There is
- not much interest in actually producing the tools. FARNET (who?) might
- produce some funding for developing PD tools. Question: Who would be
- interested? No immediate interest.
-
- Action: Bernhard will send a message to the list about this and try to
- find capable implementors. Anyone interested persons should contact
- Bernhard.
-
- Client/Server Protocol
-
- The intention is to make (aggregated) statistical information available
- from a server. A strawman document is being developed. The following
- reports were given:
-
-
- o Henry Clark reported on implementation experience. Login is
- primitive direct string comparison. Separate configuration file
- defining the view of the users. Server runs use psi formant but
- don't use opstat.
-
- o Ittai Herhman reported on a similar system currently being used at
- ANS which originated at Merit. Refer to slides.
-
- o Vikas Aggarwal also showed some examples of reports. Both Vikas
- and Ittai remarked that from limited experiments they have done it
- seems that for line utilisation there is little difference between
- 15 minute and 1 minute sampling. A preliminary document is being
- done.
-
-
- The Group went into architectural brainstorm mode and reached the
- following conclusions:
-
-
- o There is agreement to generalise the authorisation passed by login
- to generic authentication strings and leave in the authentication
- method used as a local matter beyond the scope.
-
- o Select shouldn't return the data, there should be a separate "get"
- command to initiate that, multiple selections are possible and
- identified by a selection ID which can be specified by client and
- will be returned by server.
-
- 2
-
-
-
-
-
- o Status command to find out status of what is currently selected
- especially the amount of data.
-
-
- Action: Bernhard Stockman will change the strawman accordingly.
-
- Statistical MIB
-
- Consensus is that a short list of HIGLY DESIRABLE variables should be
- agreed upon and forwarded to the ?? WG for inclusion in the next
- Internet Standard MIB.
-
- Action: Bernhard will forward a list of all so far proposed variables
- to the list and re-start discussion.
