[jira] [Updated] (KYLIN-2724) Introduce metrics collector for
system metrics, like cpu, memory, etc
[ https://issues.apache.org/jira/browse/KYLIN-2724?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]
Zhong Yanghong updated KYLIN-2724:
----------------------------------
Description:
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)
> Introduce metrics collector for system metrics, like cpu, memory, etc
