Cheshire Cat Computing

Hello

I'm trying to implement the NRPE Plugins for Windows (downloaded from first post in this thread).

If I execute check_vmem.exe or check_vcpu.exe, I get "UNKNOWN: Failed to load vmware-tools library. Are you sure that this is host is an ESX3 Guest and vmware-tools is installed?"

OS: Windows 2003 R2 English, all current patches and sp's installed
ESX is Version 3.5 Build 113339
VMware Tools is Version 3.5.0 Build 110268, installed with default settings (so GuestSDK API is enabled per default according documentation)

The linux version of the plugin works on virtual machine with centos 5.2 with same VMware Tools Build as above.

Do I need an additional software component for windows or do I overlook a fault?

Regards
Patrick

This message means that the VI API has told us that it does not have the required statistics available.
You should check your VirtualCentre config, and make sure that the logging is set to at least level 2 for the 300s interval, with retention of at least a day. This should solve the problem.

The plugin attempts to access the VMware Tools DLL, and this message appears if it fails to load.
In this case, I would guess it is because it can't find the appropriate DLLs for some reason - maybe they are not in the windows/system directory?
I have tested this, but only against a couple of the Windows guests here (hence the 'beta' label at the top of the page). It is possible that it no longer works with slightly different versions of Windows or VMware tools; I will check it again and compare the exact versions and locations of the required DLLs.

Thanks. The problem is that this is a standalone ESX host, no Virtual Center is being used.

I'm using this ESX server as a test environment to evaluate nagios for production use on a cluster of 2 ESX hosts. If we are actually going to use it we will have VC availbla in the production environment. I'm not that much of an expert in VMWare (and especially ESX), these are my first steps in this direction. I'm doing this whole thing as a project during my job training...

This plugin really needs a virtualcentre to work, as the virtualcentre provides the full range of API stats functions. A standalone ESX host only gives a limited API and so the plugin is not able to retrieve all the data it is looking for.

Some things may work, but I've not really tested it without a virtualcentre so I cant say exactly what is supported without one.

Hi Steve

I recompiled the nrpe plugins with current GuestSDK header files from vmware (version 3.5) and they are running under Windows 2003 now.

I tested check_vmem, but the output is looking strange.

My test vm has 512MB Ram assigned, no reservartion, "normal" shares, no limit ("unlimited" checked). Mem Active is 25MB, Mem Overhead is 91 (values from VirtualCenter).

PluginOutput is:
OK: Memory size is: 2080768Mb pvt/shr/bal/swp=[0.02%/0.00%/0.00%/0.00%], 0.00% active|active=25;0;;; private=469;0;;; sh
ared=21;0;;; balloon=0;0;;; swap=0;0;;; size=2080768;0;;;

I checked your source code and have some questions about it:

memLimitMB has the value 2080768MB in my output. Is this the value that I should expect for this variable? A few calculations take this value as 100%.

What do you mean with memPrivateMB?

Thanks for your support.

Well, it looks like it only needed a weekend to relax. At least for me, monitoring CPU and memory on the single ESX host started working just fine on Saturday afternoon and has been ever since...

Thanks a lot for some beatiful software!

Can you please send me the newly compiled binaries for these plugins for testing here?

You won't be able to email them (our system blocks executables) but you can drop them off for me at http://webdropoff.auckland.ac.nz/ if you go through the email verification stage.

I'm not sure why it had the initial hiccup, could just be something weird in the VC API.

Sent you both plugins by web upload.

Is there any chance that future versions of check_vmware will be able to output performance data? This would be quite interesting to me in order to create graphes of CPU & memory usage with PNP...
