> 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)
