> flink process add cpu usage metric, user can determine that their job is
> io bound /cpu bound ,so that they can increase/decrese cpu core in the
> container (k8s,yarn). If it's nessary
> . you can assign it to me ，I come up with a idea calculating cpu usage
> ratio using ManagementFactory.getRuntimeMXBean().getUptime() and
> ManagementFactory.getOperatingSystemMXBean().getProcessCpuTime over a period
> of time . it can get a value in single cpu core environment. and user can
> use the value to calculate cpu usage ratio by dividing num of container's
> cpu core.
