As others have noted SER does not directly support SNMP but you can
easily enhance your snmpd to support it.
You add serctl fifo commands using the snmp exec directive
to monitor the number of users, transactions stuff, ...
The meminfo patch (now included) is handy and you can directly pipe
serctl fifo meminfo into SNMP and create nifty graphs.

sipsak comes in handy, i.e. sending an OPTIONS request and measuring
a) if a response comes back and b) the time processing took.

Much better would be monitoring INVITE/REGISTER response behaviour since
that usually requires a whole lot more interaction (radius, db, ..)
on SER side.
