Are you talking of SNMP traps?
Yes, we don't use them at all, and then out of the blue we'll get a purple:
clear Thu Feb 16 10:31:22 2012
Unknown trap (.1.3.6.1.4.1.111.16.2.0.1)
SNMP traps are event-based notifications. If you follow the recipe
http://cerebro.victoriacollege.edu/hobbit-trap.html for setting up trap
notifications using snmptt/sec/etc part of the config requires have a
poller that checks for expiring (soon to go purple) trap status messages
and sends a clear "no traps" message to prevent that.
We've only gotten them for one particular linux host, plus several
Exadata cels. The above OID is from an exadata cell and does appear
to be from an Oracle Exadata mib . But why would the xymon server,
only occasionally, get one of these when SNMP is not enabled? I'm not
running devmon, not sure what other ways there are to have Xymon pick
up an snmp alert?
It absolutely requires some test to generate these. Check the IP address
of the originating server that sent the trap status message, then check
what tests are running from there. Might also be worth checking Ghost
Clients to see if there are more of these that you don't know about.
devmon does not do SNMP traps in any way. It is SNMP polling only.
