Hi,

We are trying to monitor hardware health of ESXi server using plugin check_esxi_hardware.py, but we received below error

[root@s930l3301 tmp]# ./check_esxi_hardware.py -H s930e0130.rwe.com -U testusr -P testusr123
Traceback (most recent call last):
File "./check_esxi_hardware.py", line 617, in <module>
wbemclient = pywbem.WBEMConnection(hosturl, (user,password), no_verification=True)
TypeError: __init__() got an unexpected keyword argument 'no_verification'
[root@s930l3301 tmp]#

Kindly advice.

Have you installed the following package?
pywbem.noarch 0.7.0-25.20130827svn625.el7 @base

Hi,

Yes. I have installed pywbem, I am using CentOS 6.8 OS.

[root@s930l3301 tmp]# rpm -qa | grep pywbem
pywbem-0.7.0-4.el6.noarch
[root@s930l3301 tmp]#

what version of the plugin are you using? this was a known issue in the past - https://github.com/Napsty/check_esxi_hardware/issues/7 - may be best to submit a bug report here if you can't get it working since that's the author's github.

We are using the below link and version is 20160531.

https://exchange.nagios.org/directory/P ... py/details

It looks like the plugin uses the CIM port (Port 5989) to gather the information.
If your server setup to allow connections to that port and is the server setup to allow polling it's information remotely?

Yes. Both ports were opened in remote server.

Kindly advice pls ?

It looks like the plugin needs a newer version of the pywbem to run so you can try and install a newer one bu running Also, upgrade the plugin to this version at the link below.
https://github.com/Napsty/check_esxi_ha ... ardware.py

If it still fails after doing the above, verify that the username and password it correct and if they are, you would have to contact the author of the plugin.

Installed pywbem version - 0.8.0-dev

Receiving below error and verified username and password are correct.

UNKNOWN: Authentication Error
[root@s930l3301 tmp]#

Try specifying the vendor code when running the command and see if that helps. It could be that the plugin cannot determine the hardware type and then cannot authenticate.
Or
1. Make sure you are either using the ESXi root user or that you create a user which is member of the root group.
2. The password you are using has some special characters like a question mark and you need to quote them.
3. The password you are using has a Dollar sign ($) which you need to single-quote.
