Nagios Plugin to Check Extreme Networks Devices

Over at INEX we’ve embarked on a forklift upgrade of the primary peering LAN using Extreme Networks Summit x670’s and x460’s. As usual, we need to monitor these 24/7 and we have just written a new Extreme Networks chassis monitoring script which should work with most Extreme devices.

It will check and generate alerts on the following items:

  • a warning if the device was recently rebooted;
  • a warning / critical if any found temperature sensors are in a non-normal state;
  • a warning / critical if any found fans are in a non-normal state;
  • a warning / critical if any found PSUs are in a non-normal state (or missing);
  • a warning / critical if the 5 sec CPU utilisation is above set thresholds;
  • a warning / critical if the memory utilisation is above set thresholds.

You’ll find the script in this Github repository: barryo/nagios-plugins.

A some verbose output follows:
