Hello,
I am trying to understand the way that the vSphere QueryPerf API works. Comparing collections between the vCenter and the MOB, for an intervalId of 300 and a startTime of vCenter currentTime - 10 minutes, if I leave out the endTime from the PerfQuerySpec for a given VM/CPU metric, the results in the MOB lag the vCenter performance by about 5 minutes. When I put the vCenter currentTime in the endTime property, the results are more in sync with that of the vCenter.
Judging from the documentation: "When endTime is omitted, the returned result includes up to the most recent metric value. When an endTime is specified, the returned samples include the sample at endTime", I would expect to get the same results in either case. Is there an explanation for what I am seeing?
This is more of a general question, but I can furnish more details.
Thanks in advance,
