Hello Jim: Thank you very much for the help, after changing the last line in the submit_check_result script from the default of: `$echocmd $cmdline >> $CommandFile` to: sg nagiocmd -c "echo '$cmdline' >> $CommandFile" everything works fine. As for my setup, I run nagios 3 and Nagtrap. However I send the notifications as passive checks directly from snmptt's EXEC statement. I some special logic in my script to select the right alarm level and then send it to nagios with submit_check_result. I link to nagtrap using the action_url in all my snmptrap services. I catch all the traps in Nagtrap, however only some of them generate alarms. Whenever an alarm is generated by the selected traps, you can always check the rest of received traps in nagtrap.

I'd be interested to know what instructions you followed to get your method working? I moved to using NagTrap because I found that maintaining the submit_check_result script was rather time-consuming, but if things have moved on a bit since I last set mine up I'd be interested to see if it's any easier to maintain now. I quite like NagTrap, but if you follow the standard install for it, there's a lot of polling the database which is very cpu intensive compared with writing direct to the command file as you do. Also, the alerts aren't so meaningful with NagTrap as they are in your setup. Cheers, Jim </blockquote></div>
