SNMP Traps for configuration changes.

Here's what I know, SNMP Traps are captured for specific events. You can configure /config/user_alert.conf to throw SNMP Trap or execute some commands etc. But when you are looking for any configuration level changes, is there any specific event you want to capture or in general.

Lets say you want to capture any events like create VS,

alert testsnmp "cmd_data=create ltm virtual" {
    exec command="echo virtual being created| wall"
}

On the console when some creates it,

(/Common)(tmos) create ltm virtual dummpyvip destination 12.34.56.78:443
(/Common)(tmos)

Echo happens in the console,

Broadcast message from root (Sat Aug 19 06:38:48 2017):

virtual being created

In similar manner you can define the SNMP Trap,

alert  "" {
   snmptrap OID=".1.3.6.1.4.1.3375.2.4.0.XXX"
}

Refer Article. Replace XXX with a number unique to this object ID. You can use any object ID that meets all of the following criteria:

The object ID is in standard OID format, and within the following range: .1.3.6.1.4.1.3375.2.4.0.300 through .1.3.6.1.4.1.3375.2.4.0.999
