Hi Team,

After adding Esxi host, I am getting the below error in service status.

Error code: Return code of 127 is out of bounds. Check if plugin exists)

Please help on this.

Hi,
What is the command used for this service check?

To find out:
Nagios XI GUI > Configure > Core Config Manger > Services
Now, select the "CPU Usage for VMHost" > click "Run Check Command" > "Run Check Command"
Now, please copy the whole command as showed and post its here, to this post/ticket.

Could you please run the below ONE line command on your XI command prompt?
Please replace "x.x.x.x" with the IP of your VM Host:

Please post output of the above command to this post/ticket.

Hi,

Please confirm, before executing these commands any backup we need to take.

Venkata Reddy

Hi Venkata,
The first two commands are used to find where "Parser.so" is located.

The next command is to install missing "perl-HTML-Parser" perl module.

No need to do any backup.

Hi Venkata,
Please NOTE that this plugin is not from Nagios. I checked and the owner of this plugin is "op5", so I will try my best to help you with this ...

Please follow the KB URL below and re-install the followings:
• SDK Prerequisites
• VMware Perl SDK on the Nagios XI server
Important Note: You must download and install VMware SDK version 7.0 if you are installing on a RHEL/CentOS 8 system. For all other supported OS distributions, we recommend downloading and installing WMware SDK version 6.5.
https://assets.nagios.com/downloads/nag ... ios-XI.pdf


I googled and found that most people were able to solved the issue by re-installed "VMware-Perl-SDK 6.5".
https://support.nagios.com/forum/viewto ... =7&t=41915

So, please following the KB at the top to re-install both the prerequisites and WMware SDK 6.5
NOTE: If you are on RHEL/CentOS 8, then please use VMware SDK 7.0

Please work with your sys-admin on this as he/she will knows more about their system settings.


Best Regards,
Vinh
