- Please don't post files in funny formats - text only. Assuming
everyone has AbiWord is as unhelpful as people assuming everyone has MS
Word available.
- In general, never post real ip addresses, passwords or SNMP community
strings in an open forum. Your email has already been indexed, and your
community string is now compromised. I would change it immediately.
Generally, the first place to start when troubleshooting plugins is to
run the plugin from the command line, with the exact same params as
you're passing in the service definition, although its common for the
check_command in the service definition to be a redefined version of a
plugin, defined in the command def file.
so:
(the following is from 2.x series. I haven't even looked at 3.x yet, so
don't know if any of this has changed).
- find where your commands are defined. Look in nagios.cfg, where ever
that might be ("locate nagios.cfg" should work) - that will tell you the
name and location of the command file. Then find the "define command"
block that matches your check_command. Use the stuff given in the
"command_line", with the params from your service definition, to run it
manually. Make sense?
If it works as root, su to the nagios user, and try it that way.
Given that this is a forum of people helping each other, the more you
can do yourself, the better your questions will be received. If you have
trouble with the above, look at it, run check_snmp -h for help, think
about it, google it a few ways before posting back. You'll also learn
more that way.
Good luck...
