A new version (20180329) of the monitoring plugin check_esxi_hardware is available.
This version contains an improvement and is based on issue #26 in which Github user storm49152 suggested another method of determining the version of the pywbem python module.
The idea to use the pywbem's internal __version__ function is great but some tests revealed that the "original" 0.7 version of pywbem didn't include such a function. To not break compatibility, a try clause was added. The added code tries to determine pywbem's version using the internal __version__ function. If it fails, it uses the external module pkg_resources.
