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:

Hi,
Looks like you might have issue with missing perl modules.

Please run the below command on your XI command prompt, please post outputs to this post/ticket:

Code: Select all

rpm -qf /usr/lib64/perl5/auto/HTML/Parser/Parser.so

Also run this and please post outputs to this post/ticket:

Code: Select all

find /usr -type f -name "Parser.so"

Now, try to install, using yum:

Code: Select all

yum install perl-HTML-Parser

Try the command again. (NOTE: below is a ONE line command):

Code: Select all

/usr/local/nagios/libexec/check_vmware_api.pl -H "10.105.0.28" -f "/usr/local/nagiosxi/etc/components/vmware/AAM01T05_VH01_auth.txt" -l "CPU"

Hi,

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

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,
Good morning!! ...

Looks like you have two "Parser.so" files.
Please run the below command to rename the "Parser.so" to "Parser.so.notUsed"

As "root", please run the below ONE line command:

Code: Select all

mv -f /usr/lib64/perl5/auto/HTML/Parser/Parser.so /usr/lib64/perl5/auto/HTML/Parser/Parser.so.notUsed

Now, please re-ran the check command again:
NOTE: The below is a ONE line command

Code: Select all

/usr/local/nagios/libexec/check_vmware_api.pl -H "10.105.0.28" -f "/usr/local/nagiosxi/etc/components/vmware/AAM01T05_VH01_auth.txt" -l "CPU"

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
