Problems with monitoring of VMware guest machines

[Bojikravov]

Hi, I 'm using nagiosxi-2012 R1.2-ovf-64, I've got problems with monitoring a VM guest machine on ESXi 5.1 (799733) host.
My current VMware cofiguration wizard is 1.1 (Nagios said that is up to date),
According "Monitoring_VMware_With_Nagios_XI.pdf" I've made permissions:

Code: Select all

chown nagios.nagcmd /usr/local/nagiosxi/html/includes/configwizards/vmware/scripts/getguests.pl 

Code: Select all

chmod 775 /usr/local/nagiosxi/html/includes/configwizards/vmware/scripts/getguests.pl

After that i followed Mr. Miltchev's post (http://support.nagios.com/forum/viewtop ... sdk#p37953)
and I used these command to make SDK Prerequisites

Code: Select all

yum clean all
	yum erase perl-XML-SAX-Base-1.04-1.el6.rf.noarch
	yum install perl-XML-SAX -y
	yum install perl-Nagios-Plugin libuuid* perl-XML-LibXML –y

After that upload file VMware-vSphere-Perl-SDK-5.1.0-780721.x86_64.gz (last version on vmware site) and successfully install VMware Perl SDK.
So far so good.
I add my ESXi host to Nagios without any problems, and saw his service details (CPU, RAM etc.)
But when I try to add virtual machine that belongs to that ESX host (check Monitor a guest VM on the VMWare host) on Guest Selection I recive
"It appears as though the VMware SDK has not yet been installed on your Nagios XI server. You must install the SDK before you are able to use this wizard"
Do you have any suggestions?
I'll be thankful.

[lmiltchev]

Did all of the prereqs installed fine, or you had some messages about "older" perl modules, etc.?

Also, let me clarify... When you run the VMware Monitoring Wizard, you enter the IP address of the vmware server (host), the credentials, and then if you select:

1. Monitor the VMware host - you can proceed with the wizard and monitor the guest fine

2. Monitor a guest VM on the VMWare host - you don't see guest VMs on this host, and you receive the following message:
"It appears as though the VMware SDK has not yet been installed on your Nagios XI server. You must install the SDK before you are able to use this wizard"

Is this correct?

[Bojikravov]

Hi,
I'm not sure about messages for older perl modules... all installations passed fine. My fault. Tomorrow I'll make a new installation.

In VMware monitoring wizard, when I put my credentials for host I can choose between:
- monitor host or VM on that host.
When I choose to monitor the Host and finish the wizard everything works fine.
But when I choose to monitor virtual machine on that host I receive "It appears as though the VMware SDK has not yet been installed on your Nagios XI server. You must install the SDK before you are able to use this wizard"

I tried to install older version of SDK Tools (5.0) and the result was the same, I can't see a list of VM's of target ESXi host.

Can you run the following commands in terminal and show us the output?

It seems like that you have all of the required packages installed. I am not sure why you cannot see the guests. What is the output of the following command?

Code: Select all

yum list installed libuuid

How many guests do you have on this particular host? I assume you can log in the ESX server using same credentials and see all of the guest VMs.

[Bojikravov]

On ESXi host machine I run 7 VM's.
On Monday I'll run command and send you feedback.

Thankс for your attention.

We did have a couple bugs with the wizard around the time of this release. Can you re-install the wizard through Admin -> Manage Config Wizards
