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.

Check some aspects of VMWare ESX guests (cpu, memorry, netio, kernel and status)
These plugins were developed by Altinity as part of Opsview software ( Plugin development was sponsored by GotVMail (

These checks are written in perl and use snmp (via perl Net::SNMP module) to query the VMWare ESX server for different aspects of the guest OS's.

This script is buggy. I have 9 virtual machines on my hosts and the 9th as the SNMP index 416 in the table.
The code to get the id of a machine makes the assumption that there are a 1:1 relation between the number of machines and the SNMP index.
This is the same bug present in check_snmp_cisco_ifstatus.

As stated above try this script instead:

Beware that with ESX 4.0 you have to explicitly activate the OID and if you have already Net-SNMP running your task is to make the two SNMP agents coexist.

I found these plugins very easy to use thank you. Some reliability problems with a couple of them though. I have found more recent versions are available at which so far seem to be better.
