When the number of widgets in a service in Ambari is large (more than about 10), all widgets show “No Data Available”. I looked Chrome’s Inspector and found the warning messages like ““Metrics with name "regionserver.Server.ScanNext_95th_percentile._max" not found to compute expression”. Those messages do not appear when widgets are shown as I expected.
I increased Ambari Metrics’ parameter “Metrics service default result limit” (timeline.metrics.service.default.result.limit) from 15840 to 35840, but it did not solve that problem.
How can I solve this problem?
