ESX3 CRITICAL - HOST-VM IO Unknown error

[crewnocdb]

We just installed Nagios XI and added our vcenter server and all of our guests are showing "Service State" as Critical. The status information shows "ESX3 CRITICAL - HOST-VM IO Unknown error".

vCenter isn't showing any issues with the hosts or the guests. Where do I start to troubleshoot this issue?

Thanks,

Try and upgrade the check_esx3.pl plugin to version 0.7.1 and see if that fixes the error.

First, login to the XI server as root and make a backup of the existing one by running the following.

Code: Select all

cp /usr/local/nagios/libexec/check_esx3.pl /usr/local/nagios/libexec/check_esx3.pl.old

Then run the following to install a required Perl Module for the new plugin.

Code: Select all

yum install perl-Nagios-Plugin

Then download this updated plugin to your PC.

Code: Select all

https://github.com/shinken-monitoring/pack-vmware/blob/master/libexec/check_esx3.pl

After it is downloaded, login to the XI GUI and go to the Admin > Manage Plugins menu
Browse to the new plugin and then click on the Upload Button.
Wait for the next check to happen and see if the unknown error is gone.

Thank-you will give that a shot and see how it goes.
