---------------------------------------
Hi [~yimingliu], I'll move this jira out of the sub-tasks of [KYLIN-2721 |
https://issues.apache.org/jira/browse/KYLIN-2721], since there's some concern.
> Introduce metrics collector for system metrics with different frequencies
> -------------------------------------------------------------------------
>
> Key: KYLIN-2724
> URL: https://issues.apache.org/jira/browse/KYLIN-2724
> Project: Kylin
> Issue Type: Sub-task
> Reporter: Zhong Yanghong
> Assignee: Zhong Yanghong
> Priority: Major
>
> For system metrics, we made an extension by introducing collecting frequency.
> Since collecting all of system metrics too frequently may bring heavy
> workload to servers, and different kind of metrics owns different priority,
> we divide system metrics into three groups with different collecting
> frequencies as follows:
> * high frequency metrics(cpuUsage, jvmCpuUsage, jvmMemAvail, javaFDs, sysFDs)
> * medium frequency metrics(jvmMemTotal, jvmVirtualBytes)
> * low frequency metrics(avgSystemLoad, serverUpTimeInHrs, physMemAvail,
> physMemTotal, jvmMemUsed, jvmPrivateBytes, maxJavaFDs, maxSysFDs)
