Follow these steps to determine if the problem is on the VMWare side or on the VMWare SDL compnent that Chnage Auditor uses?
1. Download and install VMWare vSphere PowerCLI:
2. Restart the server to complete the PowerCLI installation
3. Launch the vSphere PowerCLI prompt
4. Execute this command:
Connect-VI Server -Server <servername> - specify the name of the server hosting the virtual machine
5. Specify credentials when prompted
6. Execute the following command to obtain event list:
Get-VIEvent -Entity (Get-VM -Name virtual machine) -Start 10/19/2015 -Finish 10/20/2015 | out-file c:\temp\vmevents.txt
7. Send the output file, i.e. vmevents.txt, to the case for review by R & D.
If the test results confirm that PowerCLI behaves exactly the same way as the VMWare SDK, then the problem is on the VMWare side.
Optionally, try a newer version of the PowerCLI (5.1) to see if the issue is version-specific (chances are it is not):
Consider contacting VMWare support to investigfate why PowerCLI does not return Event.FullFormattedMessage field correctly.
