Help Support Ethan

A Message From The Founder...

As the founder of Nagios, I'm asking for your help in a cause that's dear to my heart.

I'm launching a new project to help better the world by providing the information, ideas, and inspiration that I believe can improve the lives of people everywhere.

I know you're busy managing networks, but I would appreciate it if you would consider liking my Facebook page and showing your support for the content and messages I produce by sharing them with your friends and family.

You can learn more about my project by visiting Thank you for your time. I wish you all the best in your endeavors, whatever they may be.

- Ethan

This script monitors the temperature of a Cisco catalyst via SNMP.
It requests some data of a catalyst via SNMP to analyze them and notifies you via Nagios if the switch is getting to hot.

This script should be called with -s [SWITCHIP], -C [COMMUNITYSTRING], -w [WARNLEVEL] and -c [CRITLEVEL]. For more information just run it with -h.

Tested with different IOS versions and SNMP protocol version 2c. If you want to use a different SNMP protocol version, just modify the Net::SNMP->session(...) call.

Works perfectly on my 4507R-E (11 sensors!) and multiple 3750X stacks. Does not work on 2960G or 2950 - probably no sensor.
tested on cisco catalyst 2960s (stacked) and it works perfectly

./ -s XXXXXX -C public -w 40 -c 50
OK: SW#2, Sensor#1, GREEN : 36 Grad C normal! SW#1, Sensor#1, GREEN : 36 Grad C normal!
