Unable to add ESXi host

Posted: Thu Mar 15, 2018 7:54 am

Hi,

I was able to add few ESXi host in Nagios after which it throws an error that VMWare SDK Perl is not installed.
The exact error message is "It appears as though you have not installed VMware SDK or ESXi plugins on your Nagios XI Server. You must have these components properly installed on your system before using the wizard".

This is weird. VMware SDK was installed and I was able to add few hosts.

Request someone to assist in this.

Thank You

What is the version of the ESXi server, that you are trying to monitor, and the SDK, installed on the Nagios XI machine? Did you follow our official documentation?

https://assets.nagios.com/downloads/nag ... ios-XI.pdf

When do you see this error - when selecting "Monitor the VMware host" or "Monitor a guest VM on the VMWare host" in Step 1 of the VMware wizard?

Did you get any error messages after you installed SDK, e.g. some of the perl modules being too old?

Run the following commands from the command line and show the output:

Code: Select all

uname -a
cat /etc/*release
grep full /usr/local/nagiosxi/var/xiversion
ls -la /usr/local/nagios/libexec/check_esx3.pl
/usr/local/nagios/libexec/check_esx3.pl -h | head -10
/usr/local/nagios/libexec/check_esx3.pl -H <cliend ip> -u 'username' -p 'password' -l "CPU" -v

Hi

When I tried reinstalling the perl sdk, it did display that the cli module is too old however at the end i got a message Enjoy, --the vmware team.
Looking at the documentation, "https://assets.nagios.com/downloads/nag ... ios-XI.pdf" Pg no. 9 mentions to check if check_esx3.pl is in /usr/local/nagios/ibexec directory and it is.

Please find the output of the commands

Hi

The version of ESXi server is 6.5 U1. SDK is installed in the Nagios server becoz of which i was able to add 9 ESXi hosts which are running the same version.
I followed the documentation - >https://assets.nagios.com/downloads/nag ... ios-XI.pdf
I have tried uninstalling and reinstalling the perl sdk. The outcome of the installation is
The installation of vSphere CLI 6.5.0 build-4566394 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.

The following Perl modules were found on the system but may be too old to work
with vSphere CLI:

MIME::Base64 3.14 or newer
Try::Tiny 0.22 or newer
LWP 6.15 or newer
LWP::Protocol::https 6.04 or newer
Socket6 0.23 or newer
IO::Socket::INET6 2.71 or newer
Net::HTTP 6.09 or newer

Enjoy,

i have not run the last command...

based on the error, i checked where the functions.pm file is located
[root@sadc3nagiost1 ~]# find / -iname functions.pm

When i tried to copy the functions.pm file to /usr/local/nagios/libexec/check_esx3.pl it prompted if i wish to overwrite it, which I didnot want to and havent proceeded further.

Request you to assist in this further.

Thank You.

Based on the output below:
[root@sadc3nagiost1 ~]# /usr/local/nagios/libexec/check_esx3.pl -h | head -10
Can't locate Nagios/Plugin/Functions.pm in @INC (@INC contains: /usr/local/lib64/perl5 /usr/local/share/perl5 /usr/lib64/perl5/vendor_perl /usr/share/perl5/vendor_perl /usr/lib64/perl5 /usr/share/perl5 .) at /usr/local/nagios/libexec/check_esx3.pl line 40.

I tend to believe that you are missing the Nagios::Plugin::Functions module. You verify if the module is installed, and check it's version by running:

Code: Select all

perl -MNagios::Plugin::Functions -le 'print $Nagios::Plugin::Functions::VERSION'
If the module is not installed, you could try installing it by running:

Code: Select all

cpan -i Nagios::Plugin::Functions
As far as the outdated perl modules below:
The following Perl modules were found on the system but may be too old to work
with vSphere CLI:

MIME::Base64 3.14 or newer
Try::Tiny 0.22 or newer
LWP 6.15 or newer
LWP::Protocol::https 6.04 or newer
Socket6 0.23 or newer
IO::Socket::INET6 2.71 or newer
Net::HTTP 6.09 or newer
you could try installing cpanm:

Code: Select all

curl -L http://cpanmin.us | perl - App::cpanminus
then updating the modules one-by-one:

Code: Select all

cpanm <name of the module>
or with one go:

Code: Select all

cpanm MIME::Base64 Try::Tiny LWP LWP::Protocol::https Socket6 IO::Socket::INET6 Net::HTTP
If installing of a particular module fails, you could try forcing it by running:

Code: Select all

cpanm -f <name of the module>
Also, check the version of the VMware wizard that you have on your system - Admin > System Extensions > Manage Config Wizards. Check for updates by clicking on "Check for Updates" button under the "Manage Configuration Wizards" page. If there is a newer version of the VMware wizard to the one that you are currently using, install it.

Let us know if this helped.

Pls advice.

OK, can you try running the command below?

Code: Select all

cpan -i Nagios::Monitoring::Plugin
This should install the Nagios::Monitoring::Plugin module via cpan.
Which one do you think is the better option...Going with vMA or with VMWare SDK Perl?
Both have pros and cons. SDK is a pain to install sometimes, but once this is done, configuration is easier. VMware checks a CPU intensive, so running these checks locally on the Nagios XI server increases the load. When using the box293_check_vmware.pl plugin, you don't have this problem but configuration is more involved.

Keep in mind that vMA is being deprecated though:

Hi,

I went thru the documentation for vMA which has been deprecated. When we had a meeting with Shammas, he suggested to use vMA.

I have run the command suggested by you and here is the output
[root@sadc3nagiost1 ~]# cpan -i Nagios::Monitoring::Plugin
Reading '/root/.cpan/Metadata'
Database was generated on Sun, 18 Mar 2018 19:29:02 GMT
Nagios::Monitoring::Plugin is up to date (0.51).

I rebooted the server and tried to add vmware host and I still get an error that VMware SDK or ESX Plugins is not installed.

What version of the wizard are you using? This can be found under Admin > System Extensions > Manage Components. You may have a newer version that expects Nagios/Plugin/Functions.pm when in fact it is found under Nagios/Monitoring/Plugin/Functions.pm. Try editing /usr/local/nagios/libexec/check_esx3.pl and adding "use Nagios::Monitoring::Plugin;":

Code: Select all

$ENV{PERL_LWP_SSL_VERIFY_HOSTNAME} = 0;
package CheckVMwareAPI;
use strict;
use warnings;
use vars qw($PROGNAME $VERSION $output $values $result $defperfargs);
use Nagios::Plugin::Functions qw(%STATUS_TEXT);
use Nagios::Plugin;
use Nagios::Monitoring::Plugin;  <-------------------- ADD THIS LINE
use File::Basename;
use HTTP::Date;
use Data::Dumper qw(Dumper);
...

Hi,

Thank you for the response.

I am not sure which component version you are looking for as I can see many components and their versions.

I added the line as suggested by you. use Nagios::Monitoring::Plugin;

As we cant keep living with this issue, i reverted the Nagios instance to a working snapshot and was able to add hosts.

However when I try to add vcenter server instead of individual hosts, Nagios considers it as any other OS and doesnot pull out hosts, datastores, networks or other components of vCenter Server. And for ESXi hosts, the memory utilization is not showing up. Is this a bug that memory utilization will not show up for ESXi hosts. The version we are using is 6.5 U1 Patch 2.
