Description
SystemStatusListener.java
我们看到cpu usage是support container的,为什么system load average没有support container呢?
多谢!!!
BTW, Google Cadvisor里面可以拿到container的system load average信息: container_cpu_load_average_10s (https://github.com/google/cadvisor/blob/master/docs/storage/prometheus.md)
```
@Override
public void run() {
try {
OperatingSystemMXBean osBean = ManagementFactory.getPlatformMXBean(OperatingSystemMXBean.class);
currentLoad = osBean.getSystemLoadAverage();
/*
* Java Doc copied from {@link OperatingSystemMXBean#getSystemCpuLoad()}:
* Returns the "recent cpu usage" for the whole system. This value is a double in the [0.0,1.0] interval.
* A value of 0.0 means that all CPUs were idle during the recent period of time observed, while a value
* of 1.0 means that all CPUs were actively running 100% of the time during the recent period being
* observed. All values between 0.0 and 1.0 are possible depending of the activities going on in the
* system. If the system recent cpu usage is not available, the method returns a negative value.
*/
double systemCpuUsage = osBean.getSystemCpuLoad();
// calculate process cpu usage to support application running in container environment
RuntimeMXBean runtimeBean = ManagementFactory.getPlatformMXBean(RuntimeMXBean.class);
```
Contributor guide
Research direction
Start with SystemStatusListener.java and inspect how OperatingSystemMXBean#getSystemLoadAverage() is used alongside getSystemCpuLoad() and the runtime bean. Compare the current container-aware CPU handling with cAdvisor's container_cpu_load_average_10s metric. Done means the issue's container system-load support is addressed and its behavior is verified.
