Use yum's "provides" feature. Something like `yum provides "perl::version"`

This should list all the pkgs that satisfy this requirement. We have constructed a system for doing this in our installer scripts, here is an example that installs "SNMP" and "Config::IniFiles".

I just went through the EPEL, Dag, and Core repositories ... looks like the packages that you're using are the highest available versions for a standard Nagios system install. That being said, I just tried the VMware check scripts using the standard URI and version packages, and the VMware wizard and checks worked just fine. So you should be good to go with what you've got.

When you say you're having problems with the vmware-nagios.zip, have you attempted to import the wizard using the "Admin" page, under "Manage Config Wizards"?

Right - I used to be able to see in the config wizard of the several options available - one for VMware - now that is gone. I had removed the wizard thinking it needed all of the backend working before uploading the wizard - .zip file. Now that I think I'm about there - I can't seem to cross the finish line.

I have the wizard there now - stopped for a second before posting to make sure what I was seeing....and now when I run the wizard - select the radio button and hit next - this is the error message

"Error: It appears as though you have not installed the VMware SDK or ESX plugins on your Nagios XI server. You must have these components properly installed on your system before using this wizard. "

Ideas?

This message is as indicated.

It attempts to load the component and if that fails displays this message.

I don't think we're running the same VMware wizard (I'm using this one). But you should still have a /usr/local/nagios/libexec/check_esx3.pl check script from op5, so I'd try running that script on the command line and seeing what your output is.

Thing is - I have installed it - I've installed the SDK version4 and then the newer 4.1 that was released. I've installed it 4-5 times. Now within the NAGIOS gui via Firefox - trying to run the wizard and it tells me the SDK isn't there. This shouldn't be this hard.

No luck. I checked that directory and I don't have that perl script present.

And your link is exactly where I got the VMware links for NAGIOS for my vSphere 4.0 update 2 install. If there is an easier way to do this via another wizard - I'm game for it. I noticed there are 2 within the Nagios Exchange. Is one better for VMware than the other? Has anyone compared what they do differently?

That's a bit over my head I think.

I ran the command - here is the output.

I'm sorry, that was the wrong syntax, this is exactly what you should type: Just so it's clear for future the term "Something like" means I know this is not the correct syntax, but it's what I get off the top of my head. The referance here used: I'm sorry for not making this clearer in the first place.
