Nagios Support Forum

Hi,

I’ve used vmware wizard (http://exchange.nagios.org/directory/Ad ... rd/details) to configure the monitoring for vm-host/guest and it works great. I couldn’t use the same for vCenter monitoring, as there is no option to select vCenter from the wizard. I tried from command line. The help shows I can monitor the following for vCenter

DC specific :
* io - shows disk io info
+ aborted - aborted commands count
+ resets - bus resets count
+ kernel - kernel latency in ms
+ device - device latency in ms
+ queue - queue latency in ms
* vmfs - shows Datastore info
+ (name) - info for datastore with name (name)
^ all datastore info
* runtime - shows runtime info
+ list(vm) - list of VMWare machines and their statuses
+ listhost - list of VMWare esx host servers and their statuses
* recommendations - shows recommendations for cluster
+ (name) - recommendations for cluster with name (name)
^ all clusters recommendations

I’ve got outpuut for "io"
./check_esx3.pl -D <hostname> -f /usr/local/nagiosxi/etc/components/vmware/<host>_auth.txt -l io
ESX3 OK - io commands aborted=0, io bus resets=0, io read latency=0 ms, write latency=0 ms, kernel latency=0 ms, device latency=0 ms, queue latency=0 ms | io_aborted=0;; io_busresets=0;; io_read=0ms;; io_write=0ms;; io_kernel=0ms;; io_device=0ms;; io_queue=0ms;;

I’ve got the following error for "runtime" and "vmfs"
./check_esx3.pl -D <hostname> -f /usr/local/nagiosxi/etc/components/vmware/<host>_auth.txt -l runtime
ESX3 CRITICAL - Can't call method "val" on an undefined value at ./check_esx3.pl line 2462. | vmcount=40units;;

./check_esx3.pl -D <hostname> -f /usr/local/nagiosxi/etc/components/vmware/<host>_auth.txt -l vmfs
ESX3 CRITICAL - Can't use an undefined value as an ARRAY reference at ./check_esx3.pl line 2184.


I want to monitor all the data stores and the status of all vm hosts in the vCentre. May I know the recommended plugin to do this?

Thanks

I was not able to reproduce the issue. I ran all of these commands successfully against our vSphere server. Did you follow the steps outlined in our "Nagios XI - Monitoring VMware" document?

I couldn’t use the same for vCenter monitoring, as there is no option to select vCenter from the wizard.

You can modify the checks via the Core Config Manager by adding the "-D" flag.

You can try running the VMware ESX / vSphere / vCenter Monitoring Wizard, which is a 3rd party software and we cannot guarantee that it will work. There is a "vCenter" option that you can select in the wizard.

Note: If the SDK didn't install properly (or there are some other issues), this particular wizard may not work either, because it essentially uses the same plugin.

Thanks alot for your guidance.

Yes I did follow the steps "Nagios XI - Monitoring VMware" document and successfully installed the wizard. But the wizard itself said that “Monitor a VMware host or guest VM”. And there are only 2 modes available in the monitoring wizard as below. And it worked well for both Host and guest
Monitoring Mode:

Would you like to monitor the VMware host (server) or a guest VM?
- Monitor the VMware host
- Monitor a guest VM on the VMWare host

Then I tried with command line with –D option for vCentre, runtime option worked with only subcommand as below,

./check_esx3.pl -D <hostname> -f /usr/local/nagiosxi/etc/components/vmware/<host>_auth.txt -l runtime
ESX3 CRITICAL - Can't call method "val" on an undefined value at ./check_esx3.pl line 2462. | vmcount=40units;;

./check_esx3.pl -D <hostname> -f /usr/local/nagiosxi/etc/components/vmware/<host>_auth.txt -l runtime -s list
ESX3 OK - 40/41 VMs up: ITS-Tracker-Qat(UP),......., Soy02(UP), Denis(UP), Speedtest(UP) | vmcount=40units;;

I have the same issue executing vmfs info,
./check_esx3.pl -D <hostname> -f /usr/local/nagiosxi/etc/components/vmware/<host>_auth.txt -l vmfs
ESX3 CRITICAL - Can't use an undefined value as an ARRAY reference at ./check_esx3.pl line 2184.

Do I need to provide the data-store name as subcommand? What is the subcommand option to see all the datastore info?

Thanks

What version of vCenter do you have?

Vmware vCenter version 4.1.0

Thanks

Hmm, it appears that the installed API isn't returning all of the fields.

Did you get any errors when installing the SDK?

During the installation, initially it was complained lack of Perl modules. I have installed/upgraded necessary Perl modules from cpan. When I tried again it went smoothly, output as below.
========================================================================================================================
# ./vmware-install.pl
Do you accept? (yes/no) yes
Thank you.
In which directory do you want to install the executable files?
[/usr/bin]
Please wait while copying vSphere CLI files...

The installation of vSphere CLI 5.0.0 build-422456 for Linux completed
successfully. You can decide to remove this software from your system at any
time by invoking the following command:
"/usr/bin/vmware-uninstall-vSphere-CLI.pl".
This installer has successfully installed both vSphere CLI and the vSphere SDK for Perl.
Enjoy,

I am trying to copy over the sdk files with no success, how do I do this?

Are you trying to get them TO the Nagios Server? You can use secure FTP such as filezilla, or WinSCP

Looking at this again, I believe that the API may be different for vCenter and vSphere and using the commands without specifying subcommand.

I have followed the directions and I still get the same results
