You should really look into NRPE (Nagios Remote Plugin Execution) http://nagios.sourceforge.net/docs/3_0/addons.html#nrpe
There are alternate versions of NRPE that run on Windows, etc. if you must do that. Check out NagiosExchange.org for those. You should find that you can use normal plugins you already use elsewhere with NRPE to do what you need. -Jake -----Original Message----- From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED] On Behalf Of stan Sent: Sunday, July 20, 2008 10:29 AM To: nagios List Cc: Stewart Flood Subject: [Nagios-users] Thoughts about a custom plugin I have a number of isolated networks, that is networks which are deliberately non-routable to. On each of these networks, I have a single host that has a 2nd NIC thta is on the general network. I don't can't to turn on forwarding on this host. I would like to monitor some statuses on the machines on the isolated networks. I am thinking of doing this using a Nagios plugin. My first thoughts on this plugin are to have the plugin execute a script on the dual homed machines. This script would, as a first cut, ping the internal machines, and return up/down statuses. Later I might want too expand on this by having the script do some other checks on the isolated machines. After having looked at the way Nagios plugins work, i have a couple of concerns about this design. The first is the rule that says the status returned by a plugin should be less than 8 characters. The 2nd is that, for the first version of the remote script, if a machine is down, the ping could take a while to timeout. I can see how to address the 2nd concern by having a "checker script" on the dual homed machine, that maintains a "state" file, which the script called by the Nagios plugin could simply read. But how can I address the firs concern? Any other thoughts to improve this design? -- One of the main causes of the fall of the roman empire was that, lacking zero, they had no way to indicate successful termination of their C programs. ------------------------------------------------------------------------ - This SF.Net email is sponsored by the Moblin Your Move Developer's challenge Build the coolest Linux based applications with Moblin SDK & win great prizes Grand prize is a trip for two to an Open Source event anywhere in the world http://moblin-contest.org/redirect.php?banner_id=100&url=/ _______________________________________________ Nagios-users mailing list Nagios-users@lists.sourceforge.net https://lists.sourceforge.net/lists/listinfo/nagios-users ::: Please include Nagios version, plugin version (-v) and OS when reporting any issue. ::: Messages without supporting info will risk being sent to /dev/null ------------------------------------------------------------------------- This SF.Net email is sponsored by the Moblin Your Move Developer's challenge Build the coolest Linux based applications with Moblin SDK & win great prizes Grand prize is a trip for two to an Open Source event anywhere in the world http://moblin-contest.org/redirect.php?banner_id=100&url=/ _______________________________________________ Nagios-users mailing list Nagios-users@lists.sourceforge.net https://lists.sourceforge.net/lists/listinfo/nagios-users ::: Please include Nagios version, plugin version (-v) and OS when reporting any issue. ::: Messages without supporting info will risk being sent to /dev/null
