Nagios Support Forum

Also check the permissions on the files under /usr/share/perl5/VMware and edit /usr/local/nagios/libexec/check_esx3.pl, changing the second line from:

# nagios: +epn

to:

# nagios: -epn

This is a permissions issue but for the life of me I haven't been able to reproduce it. Do you have any additional security on the machine like selinux enabled:

sestatus

?

Changed check_esx3.pl:

#!/usr/bin/perl -w
# nagios: -epn


SELinux is enabled, but is in permissive mode:

# sestatus
SELinux status: enabled
SELinuxfs mount: /sys/fs/selinux
SELinux root directory: /etc/selinux
Loaded policy name: targeted
Current mode: permissive
Mode from config file: permissive
Policy MLS status: enabled
Policy deny_unknown status: allowed
Max kernel policy version: 28

Running the check command as the nagios user still errors out: ESX3 CRITICAL - HOST CPU Unknown error

@benjohns, Please try using the updated plugin that I've attached to this post. Don't forget to give it the permissions:

Installed the new plugin:

-rwxr-xr-x. 1 apache nagios 169439 Mar 2 15:54 check_esx3.pl

Then ran chmod:

-rwxrwxrwx. 1 apache nagios 169439 Mar 2 15:54 check_esx3.pl


Now XI is throwing this error when trying to run the check:

(No output on stdout) stderr: 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
BEGIN failed--compilation aborted at /usr/local/nagios/libexec/check_esx3.pl line 40.

@benjohns, Please try the following command to install the missing module:

After installing perl-Nagios-Plugin, the checks are again timing out from within XI:

(Service check timed out after 180.01 seconds)

Running the check command from within CCM yields the following output:

[nagios@HOST ~]$ /usr/local/nagios/libexec/check_esx3.pl -H "ESXi IP" -f "/usr/local/nagiosxi/etc/components/vmware/ESXiFQDN_auth.txt" -l "CPU"

I am testing these checks each time against multiple ESXi hosts; all of our ESXi hosts are on the same VMware build.

First, disable selinux and see if that fixes the issue.
Sometimes permissive mode causes issues.

Second, verify that the username and password in the auth file is correct. Third, verify that the permissions for the auth file is correct.
This is an example of how they should be set. Let us know if any of the above is causing the issue.

1 - $ sestatus
SELinux status: disabled

2 - Credentials are correct

3 - -rw-r--r--. 1 apache nagios 37 Feb 27 15:00 [HOST]_auth.txt

I disabled SELinux, then verified the other two. Service checks are still timing out:

(Service check timed out after 180.01 seconds)

Let's turn on debugging in Nagios so we can see what the issue is when the check is ran.
Edit the /usr/local/nagios/etc/nagios.cfg file and change the following options to the values in the example below. Save the changes and restart nagios by running Then, let the check run notmally in the XI GUI and when it times out, look in the debug file And post any information on how the check was ran and any errors.

FYI, the debug file fills up quickly so if you miss the entries, you may have to try again.
