How i can map this information to Charts. i..e. Hive canary chart. How i can map if the charts are associated with an issue. Any detailed information related to charts is required by me. How to corelate an issue with charts.
If you don't mind, could you please share us which charts you would like to understand and also the errors which you would like to correlate with charts so that we will get a chance to help you in understanding ClouderaManager-->charts
i.e. If i receive the alert with Activity Monitor.
Pause Duration Bad
Average time spent paused was 2 minute(s), 54 second(s) (290.37%) per minute over the previous 5 minute(s). Critical threshold: 60.00%.
There are various charts like disk latency,Disk throughput,networkthroughput. Garbage collection time.
How I can understand due to which this problem occurs in system. Will any of the specific charts help me there.
This is a garbage collection (GC) pause.
Check how much JVM Heap had been used for the service (HS2 etc..) for which you received this Alert.
From the alert, you can see that JVM pause takes 2+min and you have configured to alert if GC pause takes 60% of 1min. You should see the JVM Heap Memory Usage and GC pause charts in the Service(for which you see this alert) and check If the heap is constantly high then that is the likely reason. In that case, the solution could be a simple as increasing the heap size.
