Description of problem:
performance collection in the customer environment stops abruptly
Version-Release number of selected component (if applicable):
5.5.2
How reproducible:
customer environment only
Steps to Reproduce:
1. set up one appliance to do performance capture for one zone
2. let collection run
3. access the utilization data of multiple vms
Actual results:
not all vms have performance data available
Expected results:
all performance data is being collected
Additional info:
collections are missing and it seems the holes they form cause the graphs not to be computed
I see one culprit:
[hourly] Rollup for VmVmware name: [T1KDB1], id: [12000000000715] for time: [2016-02-06T05:00:00Z]
Looks like that one failed

I agree that this is odd.

If a vm is no longer available, it will show up as nil. Possibly this VM went away?
I believe this is due to either cap&u timer running too long/timing out, or cap&u running too long/timing out.
We are aware of cap&u timer running too long and have a number of fixes in 5.6/5.7 to speed it up.
We have cap&u performance tweaks, but unsure the speed difference
