hp switches and checking snmp

[Michael Hertrick]

Todd,

I am monitoring an HP Procurv switch.  MRTG logs the interface I/O and 
error counters (and graphs them, of course).  The check_mrtg[traf] 
plugin monitors the MRTG log files for threshold breaches.  This way 
only one query per check interval is necessary.  I don't use check_snmp 
because each device would be queried twice per interval, once with MRTG 
and once with check_snmp.

For system events, like bad fan or module failure, can you configure 
your HP switch to send SNMP traps to the Nagios host?  Using traps cuts 
down on monitoring load since a trap is only sent when there is an 
event.  Have you read the Nagios documentation on using SNMP event 
handlers? 

I do not monitor the HP switch SNMP traps, though; so I can not say 
whether that part works well.  For whatever it's worth, I can't think of 
any reason it wouldn't.

>Is anyone using nagios to monitor hp switches with the check_snmp plugin?  All we want to know is if there is an error (like bad fan) in the logs and if there is any huge traffic.   I have done this with Procurv manager but i would prefer to use nagios incase we have to switch brands (to cisco).
