Nagios XI and VMware

[azubarev]

Hi guys! We have esxi 6.0 platforms at our environment, I've installed prerequisitions for monitoring according to manual, but when I try to add host via configuration wizard and choose host metrics (CPU, Memory, Networking and Memorys status, for example), I've got an error "Configuration verification failed."

I've deploy Nagios XI at esxi platform by downloaded VMware template.

Here is some information

uname -a

Linux vnagiosxi 3.10.0-957.5.1.el7.x86_64 #1 SMP Fri Feb 1 14:54:57 UTC 2019 x86_64 x86_64 x86_64 GNU/Linux

I will appreciate any help. Thank you!

Did you have any config errors/issues (that you know of) prior to running the wizard?

It's possible that you have a file that is "stuck" in the "/usr/local/nagios/etc/import" directory. To check, run the following command:

Code: Select all

ls -l /usr/local/nagios/etc/import

Try the following:

1. Run the Config File Management Tool - CCM > Tools > Config File Management Tool > Delete Files > Write Configs > Verify Files > Apply Configuration (apply configuration if there are no config errors that is)
2. Rerun the wizard
3. Check to see if you have any new issues

Hello! Thanks for the quick reply!

I haven't problems with other wizards, so I can succesfully add Cisco router for example. But I've tried all that you advised with same result.
Here is output of ls -l

[root@vnagiosxi]# ls -l /usr/local/nagios/etc/import
total 0

Hello and many thanks for the quick reply!

Here is outut of ls -l

[root@vnagiosxi tmp]# ls -l /usr/local/nagios/etc/import

So I've tried your recommendations with same result... Other wizards working with no problems, I can succesfully use Router wizard for example, but not VMware.

Can you show us a screenshot of the error that you are seeing in the GUI, and PM me your profile?

Admin > System Config > System Profile > Download Profile

I believe I found what the issue was, while reviewing the logs in the profile. I found this error:

Error: Service check command 'check_vmware_api_host!xxx' specified in service 'CPU Usage for VMHost' for host 'xxx' not defined anywhere!

For some reason, you are missing both commands that are used in the new version of the vmware wizard - check_vmware_api_host and check_vmware_api_guest. I am not sure why this happened, but here's how you can fix it.

1. Go to the Admin > System Extensions > Manage Config Wizards and delete the VMware wizard by clicking on the "x" button.

2. Open a SSH (putty) terminal to your Nagios XI server, and run the following commands as root:

Code: Select all

cd /tmp/nagiosxi
./upgrade -f

Running the upgrade script with the "-f" flag will force reinstalling all of the addons, including the VMware wizard you just deleted. It will also add the missing "check_vmware_api" commands. If for some reason you deleted the original install directory (/tmp/nagiosxi), you could re-download the tarball.

Code: Select all

cd /tmp
rm -rf xi* nagiosxi
wget https://assets.nagios.com/downloads/nagiosxi/5/xi-5.5.11.tar.gz
tar xvf xi-5.5.11.tar.gz
cd nagiosxi
./upgrade -f

After running the upgrade script, check to see if the VMware wizard and both "check_vmware_api" commands were installed. If everything is in place, try rerunning the wizard.

Hope this helps.

Thank you for the advice, you're rock! Wizard is started, trying to add our hosts. Many thanks to you from cold Mother Russia!
