Class JvmNativeMemoryMetrics

JvmNativeMemoryMetrics
public class JvmNativeMemoryMetrics extends Object
JVM native memory. JVM native memory tracking is disabled by default. You need to enable it by starting your JVM with this flag: 
-XX:NativeMemoryTracking=summary

When native memory tracking is disabled the metrics are not registered either.

The JvmNativeMemoryMetrics are registered as part of the JvmMetrics like this: 


 JvmMetrics.builder().register();
However, if you want only the JvmNativeMemoryMetrics you can also register them directly: 

 JvmNativeMemoryMetrics.builder().register();
