Prerequisites:

I ran into a lot of issues trying to get this plugin to work on my Nagios RedHat 4_Update6 host. Such as…. I received errors when using an old version of CPAN to download, build and install Perl modules required by the check_esx3.pl plugin. To resolve this I upgraded Nagios server to Redhat 5_Update 6 and also received a few awesome suggestions from the Nagiosplug-help communities.

Using the advice I was given I then took the following steps:


- Downloaded check_esx3.pl from Nagios Plugin Exchange
- As per check_esx.txt, I downloaded and installed “VMware-vSphere-Perl-SDK-4.1.0-254719.i386.tar.gz “

- I then ran the ./check_esx3.pl script and received the error:

- Using CPAN I installed the requested module: #perl -MCPAN -e 'install Nagios::Plugin'

-Tried ./check_esx3.pl and received error:

- Using CPAN I installed the requested module: # perl -MCPAN -e 'install Math::Calc::Units'
- Ran ./check_esx3.pl and received error:

(Perhaps you need to 'use' the module which defines that package first.)
