Monitor Network Card utilisation using Nagios

Question

As per this question I want to monitor the network utilisation of my Windows Servers using Nagios (not Cacti).

Does anyone have any guidance on querying the WMI counters using NSClient or via SNMP so that rrd data can be collected by nagios for graphing using pnp4nagios?

Or does anyone have a plugin that does this?

Thanks

Solution 1

Solved this by using the check_bandwidth3 plugin for Nagios and checking it over SNMP. I don't know why I didn't think of checking it via SNMP first as that's how I collect the stats for my cisco kit!

Solution 2

I'm using Centreon which provides the perl script check_centreon_snmp_traffic.

Currently trying this on Debian Lenny - Fingers x'd looks like everything I need wrapped up in a nice meta-package. As long as it works and can let me see the trends I need then I'm happy.

Have installed OpsView, Am impressed by it's user interface, but I'm still struggling to get it to display the actual bandwidth, rather than the RTA and packetloss values which I have already.

Just a word of warning--this won't work for 1Gpbs interfaces or faster since Windows only has 32-bit counters which rapidly overflow on fast uplinks serverfault.com/questions/205785/…

I've actually authored my own check plugin for Nagios for this exact reason! exchange.nagios.org/directory/Plugins/…

As per my other comment, you can now use my plugin at exchange.nagios.org/directory/Plugins/…
