check_vmware_api (former check_esx3) is a Nagios plugin made by op5 AB to monitor vmware's products.

The plugin uses the VMWare API (via HTTPS) to do a wide variety of checks. You can check out the latest version with GIT at git://git.op5.org/nagios/op5plugins.git Requires the Nagios::Plugin CPAN module as well as the "VMware Infrastructure (VI) Perl Toolkit Packages" available from http://www.vmware.com/download/sdk/ See http://www.op5.com/support/documentation/how-to/400-monitoring-vmware-esx-3x-and-vmware-esxi for Nagios Command definitions, although the latest version of the script supports additional checks which aren't listed on that webpage yet, so you'll probably need to make a few more up.

Hi,

this works fine on our infrastructure, but we get some issue donc vcenter database growing.

every check create a Login event and a logout event in the event table of the vcenter.
We get a lot of check (2 check per VM every 5min). That is generating millions of lines in the vcenter database which became very slow. We already reduce the event&task conservation time but not enough.

Does anyone know a way to limite the number of login to vcenter done by the check ?

Good check here.
Work like a charm when I launch this by command line (ie. ./check_vmware_api -H 192.168.2.25 -u supervision -p **** -l runtime -s status )

But when I launch this in NAGIOS I get : (Service Check Timed Out)

I already tried to install older Net-Http perl module (v 6.3)
perl -MCPAN -e shell
install GAAS/Net-HTTP-6.03.tar.gz

But nothing change.

Any help here ?

Hi all,
for timeout issues with this plugin like:
/check_vmware_api -H xxxx -u root -p xxxx -l cpu
CHECK_VMWARE_API UNKNOWN - plugin timed out (timeout 30s)

the solution is to install older Net-Http perl module (v 6.3)

perl -MCPAN -e shell
install GAAS/Net-HTTP-6.03.tar.gz

There is a way to add a total datastorage usage and free space of the DC?
BTW excelent check!
Thanks a Lot

Javier
Hello,
is it possible to use it to monitor a NFS datastore latency ?
which would be the syntax?
thanks

Hi guys,

I use this script on two of my nagios (different site)

one is now in use and with a very good reply.
another one has a big issue that after i installed basic component and vmware tool kit.this script can run with out error but only a time out output.

./check_vmware_api -H xxxx -u root -p xxxx -l cpu
CHECK_VMWARE_API UNKNOWN - plugin timed out (timeout 30s)

could anyone give some suggestion on this?

You're writing - h 10.2.2.1 but -h is for showing the script help
In order to check that address you should type -H (in capital letters) host_address
I have one complaint, in that the script defines a DataCenter as the vcenter, where a DataCenter should be a data center in vcenter. I have multiple sites with multiple machines at each site, organized into DataCenters at each site and clusters inside each DataCenter.

This brings me to my only request. It would be great to be able to get the stats on the clusters themselves. Stats on the vcenter cpu as a whole For example), doesn't help me when I have machines in multiple locations that can't interact with each other. Stats for Clusters would help me tremendously to see if I am running low on resources at a particular site, and if I need to add another ESXi machine or just increase the phyical memory on an ESXi machine.

Otherwise, after installing the VMware-vSphere-Perl-SDK modules, the script runs great and works very well. It could just be a bit better with my recommendations.

does anyone have an example of this script as a nagios service. I keep getting a config error. They dont seem to log the config errors in nagios.
I can run from command line. I tried combining ars named pair separate and together but still get error.
command line from libexec dir
check_esx -h 10.2.2.1 -l CPU -u ss -p wer
in config file
define service{
use local-service ; Name of service template to use
host_name frhg-vcenter
service_description CPU
check_command check_esx!- h 10.2.2.1!-u ss!-p wer!-l CPU
notifications_enabled 0
}

Any ideas or examples?
