The problem is that the agent is single threaded. so the agent calls your script, then blocks while waiting for your answer. so it can't answer the query from your script, because it's waiting for your script to finish. catch-22. In theory, this could work if the pass mechanism was updated to use the delegated flag, and allow other requests to be processed while a script is running. But nobody has gotten around to doing this yet. If you want to monitor specific processes, there are two other ideas I can think of. One is the proc token, which is specifically for monitoring whether or not a process is running. The other is to not use snmp in your script, and instead only use command-line tools/scripts (like ps) to get the data you want. -- Robert Story; NET-SNMP Junkie Support: <http://www.net-snmp.org/> <irc://irc.freenode.net/#net-snmp> Archive: <http://sourceforge.net/mailarchive/forum.php?forum=net-snmp-users> You are lost in a twisty maze of little standards, all different. ------------------------------------------------------- SF email is sponsored by - The IT Product Guide Read honest & candid reviews on hundreds of IT Products from real users.
