Package io.opentelemetry.instrumentation.runtimemetrics.java8

Class Cpu

java.lang.Object

io.opentelemetry.instrumentation.runtimemetrics.java8.Cpu

public final class Cpu
extends Object

Registers measurements that generate metrics about CPU.

Example usage:

 Cpu.registerObservers(GlobalOpenTelemetry.get());
 

Example metrics being exported:

   process.runtime.jvm.system.cpu.load_1m 2.2
   process.runtime.jvm.system.cpu.utilization 0.15
   process.runtime.jvm.cpu.utilization 0.1
 

In case you enable the preview of stable JVM semantic conventions (e.g. by setting the otel.semconv-stability.opt-in system property to jvm), the metrics being exported will follow the most recent JVM semantic conventions. This is how the example above looks when stable JVM semconv is enabled:

   jvm.cpu.time 20.42
   jvm.cpu.count 8
   jvm.cpu.recent_utilization 0.1
