Several users of the Nagios/Monitoring plugin check_esxi_hardware.py have informed me in the past few weeks, that the following error is shown when used against an ESXi server running IBM hardware which uses IBM iso image of the ESXi intallation.
Traceback (most recent call last):
File "./check_esxi_hardware.py", line 625, in
verboseoutput(" Element Name = "+elementName)
TypeError: cannot concatenate 'str' and 'NoneType' objects
This error is also described in the FAQ and only affected IBM servers which use the IBM ESXi image (the regular ESXi intallations from VMware worked fine).
Andreas Gottwald has sent me a patch which fixes that issue. Thanks!
Therefore with todays release, the current version number of check_esxi_hardware.py is now 20150119.
