Nagios Support Forum

We are getting the error below and everything is fine with our ESX host:

Critical
ESX3 CRITICAL - Illegal division by zero at /usr/local/nagios/libexec/check_esx3.pl line 1065.

We tried forcing an immediate check and we just upgraded Nagios to version 2014R2.0 in order to resolve this issue, but it didn't. Could someone please assist?

Is this a shared volume check? If so and if the mountpoint does not exist, you will get this error.

No this is not a shared volume check. This is a check for Datastore usage for a virtual host. We only have 5-6 virtual host that use this check and those are reporting fine.

How large is the size? I have seen this when the volume does not exist (thus returning 0 size and failing the division), or when the size of the datasource is larger than the plugin can handle, causing overflow and a return of 0 which again fails division.

You should check out box293_check_vmware:

There is also a wizard for it:

Thank you for your help. This can be closed.
