RE: SNMP Trap Truncated?

Hi Dave,

The monitor entry is configured as such:
monitor -r 600  -o 1.3.6.1.4.1.7143.6.9.2 "44448217: No response from local user/portal application." 1.3.6.1.4.1.7143.6.9.1 > 1200 

If I walk the mteTriggerTable then here is an example entry that I see:
DISMAN-EVENT-MIB::mteTriggerEnabled."snmpd.conf".'44448217: No response from lo' = INTEGER: true(1)

So yes the index values are being cut off. Can I change the SnmpAdminString to be something larger? Perhaps this had been larger with net-snmp-5.1.2-13.el4_7.2 when I saw this work without being truncated before.

Cheers,
Matt

This is the value of the varbind "mteHotTrigger.0', which is reporting the index value of the mteTriggerTable that caused the trap to be sent - i.e. the relevant value of mtTriggerName.

The syntax of mteTriggerName is SnmpAdminString (SIZE (1..32))
so this value is limited to 32 characters.   That appears to be
roughly the length of the value that's being logged here.

How are you configuring the monitor entry?
What is the snmpd.conf directive that you are using?

What happens if you walk the mteTriggerTable?
What sort of  index values do you see?

Dave
