> This change to display flink application cpu resources used so the user can know and adjust flink resources. This feature is particularly useful if multiple applications share resources in cluster like yarn. ``` metrics.<Double, Gauge<Double>>gauge("Load", mxBean::getProcessCpuLoad); metrics.<Long, Gauge<Long>>gauge("Time", mxBean::getProcessCpuTime); ``` The metrics above is about how much resources flink taskmanager used in machine not cluster.If machine is not same in cluster, it's too hard to know how cores flink used in cluster, the machine cores is different. And by this change, user can calculate the cpu efficiency of flink application. -- This is an automated message from the Apache Git Service.
