Hi Team,

I have tried the ESXi Hardware monitoring with check_esxi_hardware.py plugin.

I am able to run the check command from nagios server side, it's reporting properly.

Code: Select all

[root@INFSGDCNGOS03 libexec]# ./check_esxi_hardware.py -H <IPAddress> -U <username> -P <password> -C 5989 -V auto
OK - Server: Dell Inc. PowerEdge R320 s/n: xxxx System BIOS: 2.6.0 2018-06-11

but I am unable to report on Nagios check command using the plugin along with service check .

Code: Select all

$USER1$/check_esxi_hardware.py -H $HOSTADDRESS$ -U $AGR1$ -P $AGR2$ -C 5989 -V $AGR3$

Code: Select all

check_esxi_hardware_check!/home/root/.root!auto

Attaching the error screenshot from Nagios monitoring tool.

could you please address the issue and help me to sort the issue.

Thanks in advance

Regards,
Simbu

Hello, @rohithroki . If I insert the arguments from here:

/home/root/.root!auto

To this command:

$USER1$/check_esxi_hardware.py -H $HOSTADDRESS$ -U $AGR1$ -P $AGR2$ -C 5989 -V $AGR3$

Then it's going to look like this compiled:

/usr/local/nagios/libexec/check_esxi_hardware.py -H <IPAddress> -U /home/root/.root -P auto -C 5989 -V auto

Doesn't look right. This part

/home/root/.root!auto

Needs to look like this:

username!password!auto

@rohithroki, Can you run this command from the command and show me the output?

/usr/local/nagios/libexec/check_esxi_hardware.py -H <IPAddress> -U nagiosuser -P '$U2FsdGVkX1/6fICGCOTr9LEOrtKAZfGc$' -C 5989 -V auto

Your password contains special characters that are not allowed in Nagios configs. I recommend assigning the whole password to a macro and then using that macro as an argument:

$USER8$="$U2FsdGVkX1/6fICGCOTr9LEOrtKAZfGc$"

check_esxi_hardware_check!nagiosuser!$USER8$!auto

https://assets.nagios.com/downloads/nag ... Macros.pdf

But first, just run the command I gave you from the command line to make sure it's working.

Hi ,

please find the output from the command line

Code: Select all

[root@xxx libexec]# ./check_esxi_hardware.py -H <IPADDRESS> -U nagiosuser -P 'U2FsdGVkX1/6fICGCOTr9LEOrtKAZfGc' -C 5989 -V auto
OK - Server: Dell Inc. PowerEdge R320 s/n: xxxx System BIOS: 2.6.0 2018-06-11

I tried with the Macros by adding "$U2FsdGVkX1/6fICGCOTr9LEOrtKAZfGc$" but still showing null output.

please help me to sort out the issue.

Hi ,
we are using Nagios core 3.5.0 and for defining the service we are using Nconf (graphical tool )

@ rohithroki, Can you navigate to /usr/local/nagios/etc/ folder and upload the .cfg file containing the check esx command, another .cfg file containing the service check definition and finally the resource .cfg file. I haven't had much experience with Nconf but I suspect it may have written the command incorrectly, or used a wrong syntax that broke the command.

While this article is for Nagios XI, the basis is the same. You have special chars in the password you are entering that will need to be escaped, most specifically the $
