How to check for Network interface collision using Nagios
Posted on 2009-07-02
I was hoping someone knows how to do this :)
We have a few production servers that is currently monitored by Nagios. But we ran into an situation where some clients had issues, after allot of searching and trouble shooting we found that the one connecting servers (Ubuntu 6 server) had collisions on its main Network Interfaces (ifconfig lists collisions at:12925212) , all the other servers collisions were sitting at 0. We believe the connection issue is due to the collisions on the network interface (My Manager is investigating how to fix it :P ).
But now I have the task to find away to monitor the network interfaces for collisions and if there is, an alert or notification needs to be sent.
Thus is there away to use Nagios to monitor a Linux Based machines Network Interface for Collisions specifically.
