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 > note : what would be the impact here of the null values in the > metric_rollups.intervals_in_rollup value, I agree that this is odd. > and why do we have rows that show no vendor or name? 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
This is part of the fixup to perf_capture_timer. It is part of Darga and later
Keenan, can you add PR link?
