After startup of the vmware probe, an alarm was generated:
vmware alarm message:
"<hostname> is not responding (reason: Unexpected fatal error in data collection. Collection will not resume until probe is restarted. See log for details. )"
Not enough memory configured.
Increase java memory for the vmware probe, for example using raw Configure increase the min/max memory values to:
options = -Xms2048m -Xmx4096m -Duser.language=en -Duser.country=US
Then click Ok/Apply
Then 'cold start' the probe (Deactivate-Activate).
