![]() ![]() The way the trap receiver sensor works is that the error clears and goes green as soon as the next polling cycle happens, i.e. If I replaced the single sensor with one sensor for each device, that could show me the origin of the alert, but it still wouldn't identify the trap (and it would be a bit of a pain to set up).Īlso, a second question about the SNMP trap sensor: Is there any way to insert OIDs into the notification message so that it's obvious what device it's coming from and/or what the trap is?

To do so edit /etc/snmp/nf and paste the following lines at the end: #ĮVENT test. Now we will create a handler for a test trap. This enables logging all incoming traps to /var/log/snmptt/snmpttunknown.log. Next edit /etc/snmp/snmptt.ini and change unknown_trap_log_enable = 0 This is needed for snmptt to recognize the incoming traps. The ‘-On’ parameter tells snmptrapd to log OID numbers. ![]() The traps for Instant AP cluster are generated with virtual controller IP as the source IP, if virtual controller IP is configured.
