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

Please check out a new plug I created today (using SNMP) for monitoring specific port switch an alert in case it is going down or up.

down -> up considered as warning (exit code 1)
up-> down considered as critical (exit code 2)
no change made -> considered as OK (exit code 0)
Please check out a new plug I created today (using SNMP) for achieving the following purpose:

Monitoring when specific port on some switch is going down or up.

The plug is only checking for changes in port state (up -> down and down -> up) and generates an appropriate alert.

1. Up-> Down considered as Critical
2. Down->UP considered as Warning.
3. In case there is no change in the state alerts will not arrive/recovery state will be considered as OK.

Tested on the following switches:

Juniper EX4550

However it should work on any other switches..

Please let me know your thoughts
