You dont need to recompile Nagios in order to installa new plugin. Read the Nagios online documentation (it is very comprehensive) to see how to define a new check command, which will be your plugin, and then you can define a service to use this check command. Where you install the plugin depends on how you installed nagios, but usually you'll have a plugins subdir under your nagios installation directory.

Remember that Nagios and MRTG are two completely separate products, although MRTG can query the Nagios agent (with the appropriate plugins) and you can embed their output in each other (with the appropriate plugins).

You can use the MRTG cfgmaker program to generate as many MRTG .cfg files as you like, and then set your MRTG instance to process them all. There is no way (that I know of) to automatically walk your entire network to discover all switches and generate configs, though.

Much documentation is available on mrtg.org (for MRTG documentation) and on the Nagios website (for Nagios documentation).

I have downloaded your check_rrd plugin yet can't get it working.
1. How/where do I install it?
2. Do I need to recompile Nagios in any way afterward?
3. What format do I create a Nagios command in to get it to work?

On a slightly separate issue:
4. I have MRTG processing one switch, but how do I create config to access multiple switch etc. (ie. my whole network infrastructure)? BTW, I have also installed NagiosQL as a GUI for nagios configs - thought it might help!

Any help (or redirection) would be appreciated !!!

Thanks
