类 SystemResourcesCounter

java.lang.Object

java.lang.Thread

org.apache.flink.runtime.metrics.util.SystemResourcesCounter

所有已实现的接口:

Runnable

@ThreadSafe
public class SystemResourcesCounter
extends Thread

Daemon thread probing system resources.

To accurately and consistently report CPU and network usage we have to periodically probe CPU ticks and network sent/received bytes and then convert those values to CPU usage and send/receive byte rates.
