Check Esxi Hardware not Working on CentOS 7

[ep7network]

Hi there. I'm glad to be back!

I'm running CentOS 7 and Nagios web interface is monitoring my other servers with no problem. I would like to monitor my disk RAID on my HP DL360 G5 server that's running OS ESXi 5.5.

On my Nagios host, I've installed "pywben" and "m2crypto" by running "yum install pywben". I've also downloaded "check_esxi_hardware.py" and moved it to /usr/lib64/nagios/plugins, I've opened ports 5989 and 443.

When I try to monitor server ESXi 5.5 from Nagios host, I go to "/usr/lib64/nagios/plugins" and run #./check_esxi_hardware.py -H 192.168.x.x -U root and receive "bash:./check_esxi_hardware.py:Permission denied" Permission denied? I've open appropriate ports. I need to make sure check_esxi_hardware.py is configured correctly! Is there a way to check?

I'm unsure what to do next! I can't find a decent online source explaining how to configure check_esxi_hardware.py on CentOS 7 correctly. Online sources I do find do not pertain to my situation. Any advice in making this work?

What are the file permissions on ./check_esxi_hardware.py ?

Code: Select all

ls -al ./check_esxi_hardware.py

Is it executable?

[ep7network]

When I ran "ls -al ./check_esxi_hardware.py" I noticed file wasn't executable. So I typed chmod a+x check_esxi_hardware.py to make file executable. I then typed ./check_esxi_hardware.py -H 192.x.x.x -U root -P [-V -i -v -p -I xx] I receive "UNKNOWN: Authentication Error". I do know I have no password set on ESXi server, which is why after -P it's blank.

What can be causing the "UNKNOWN: Authentication Error"?

[dwhitfield]

Try specifying the vendor code when running the command and see if that helps.

Code: Select all

    --vendor dell, hp, ibm, intel

It could be that the plugin cannot determine the hardware type and then cannot authenticate.

Also, what happens if you drop the -P?

[ep7network]

If I drop the -P I still receive "UNKNOWN: Authentication Error". Considering that my ESXi server doesn't have a password, I thought maybe its causing an issue. I logged into ESXi server configured a password. So now ESXi server has a password.

I logged back into Nagios server, and in CLI I entered "./check_esxi_hardware.py -H 192.x.x.x -U root -P myPasswd -V hp" and nothing happens. The curser stop blinking and nothing happens. When I Ctrl c I receive this output :

Code: Select all

KeyboardInterrupt

I've tried various combinations, regarding "./check_esxi_hardware.py -H 192.x.x.x -U root -P myPasswd -V hp -p -I de" and receive same error message.

Any advice regarding error message and how to fix it? Or do you think its a different issue?

When you ran the plugin and the cursor stopped blinking, how long did you wait before cancelling out?

Can you run the following and post the output? (Replace x.x.x.x with the VMWare host IP address)

Code: Select all

./check_esxi_hardware.py -H x.x.x.x -U root -P myPasswd -V hp -v
./check_esxi_hardware.py --version
nmap x.x.x.x -p 5989

That plugin was updated a month ago, are you running this version?

This time when I ran the plugin ./check_esxi_hardware.py -H x.x.x.x -U root -P myPasswd -V hp -v I didn't interrupt its service, in fact I left it running the entire night and this morning when I logged into Nagios server I noticed a different output. I think its working but not sure. My output is below-

Code: Select all

I think output above is a positive sign.

When I run the command ./check_esxi_hardware.py --version, I receive output below-

Code: Select all

[root@nagios plugins]# ./check_esxi_hardware.py --version
check_esxi_hardware.py 20170905

When i run nmap x.x.x.x -p 5989, I get this output-

Code: Select all

[root@nagios plugins]# nmap x.x.x.x -p 5989

Starting Nmap 6.40 ( http://nmap.org ) at 2017-10-03 11:30 PDT

To answer your question regarding if I'm running the version from
https://www.claudiokuenzler.com/nagios- ... p#Download
Yes, that is where I downloaded plugin from.

Is this working now?

[scottwilkerson]

This time when I ran the plugin ./check_esxi_hardware.py -H x.x.x.x -U root -P myPasswd -V hp -v I didn't interrupt its service, in fact I left it running the entire night and this morning when I logged into Nagios server I noticed a different output. I think its working but not sure. My output is below-

I think output above is a positive sign.

This output sure looks like the plugin is working. I guess the biggest question is how long does the plugin take to run as if it takes all night, that's going to be a problem.

Might want to try timing it with this command

Code: Select all

time ./check_esxi_hardware.py -H x.x.x.x -U root -P myPasswd -V hp -v

[ep7network]

Plugin command time ./check_esxi_hardware.py -H x.x.x.x -U root -P myPasswd -V hp -v I ran it four times. My first run took 13 minutes, 2nd run took fifteen minutes, 3rd run took twenty-four minutes, and last run took twenty-five minutes.

Is there a way to fix this?

From reading the FAQ's on the website.

It depends on how long it takes to check it from your ESXi server?
Open the Hardware Status tab of the affected ESXi server then click on 'Update' and you will see that it takes a very long time until the hardware information is collected.

Although this was from ESXi version 5 where they saw this issue.

Is your ESXi 5.5 up to date? Or what release date do you have installed?
