This is not the sort of thing you want to do with an agent. Rather, a self standing application is more appropriate. There are two ways to do it. If the set of trap destinations is known and fixed, you can write a script which monitors the file and uses the snmptrap command to send the traps. For dynamic hosts, I would suggest creating a MIB object which always sends a trap when set. The script can set that variable whenever it discovers the magic text, causing the subagent to send the trap, which is sent to all configured receivers by the master agent. Naturally, you could also embed the script into the subagent, thus eliminating the need for the MIB object, but that is a bit of a tricky operation.
