Package io.opentelemetry.instrumentation.runtimemetrics.java8

Class Threads

java.lang.Object

io.opentelemetry.instrumentation.runtimemetrics.java8.Threads

public final class Threads
extends Object

Registers measurements that generate metrics about JVM threads.

Example usage:

 Threads.registerObservers(GlobalOpenTelemetry.get());
 

Example metrics being exported:

   process.runtime.jvm.threads.count{daemon=true} 2
   process.runtime.jvm.threads.count{daemon=false} 5
 

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.thread.count{jvm.thread.daemon=true,jvm.thread.state="waiting"} 1
   jvm.thread.count{jvm.thread.daemon=true,jvm.thread.state="runnable"} 2
   jvm.thread.count{jvm.thread.daemon=false,jvm.thread.state="waiting"} 2
   jvm.thread.count{jvm.thread.daemon=false,jvm.thread.state="runnable"} 3
