io.opentelemetry.instrumentation.runtimemetrics.java8.Classes

public final class Classes
extends Object

Registers measurements that generate metrics about JVM classes.

Example usage:

 Classes.registerObservers(GlobalOpenTelemetry.get());
 

Example metrics being exported:

   process.runtime.jvm.classes.loaded 100
   process.runtime.jvm.classes.unloaded 2
   process.runtime.jvm.classes.current_loaded 98
 

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.class.loaded 100
   jvm.class.unloaded 2
   jvm.class.count 98
