The SNMP socket is created before fork, so there is not an easy way to
do this.

The possible way might be something like this:
- use FarmChildHook to get a handle to SNMP agent
- close the socket for the existing SNMP_Session
- undef the existing SNMP_Session
- create a new SNMP_Session with child specific port. See activate() for
an example of creating SNMP_Session.

This should give you one SNMP agent port per child. You could then
monitor each farm child individually.

Thanks,
Heikki
