Class JvmstatMonitor.NativeCodeCompilerInstrumentation

java.lang.Object

io.prometheus.client.utility.jvmstat.JvmstatMonitor.NativeCodeCompilerInstrumentation

Enclosing class:

JvmstatMonitor

public static class JvmstatMonitor.NativeCodeCompilerInstrumentation
extends Object

Provide visibility about the internals of the JVM's just-in-time (JIT) compiler.

Even if you do not run your Java server with -server mode, these metrics will be beneficial to understand how much is being optimized and whether a deeper analysis to find classes to blacklist from JIT rewriting exist.

Generated Metrics

jvmstat_jit_compilation_time_ms

This metric tracks the amount of time the JIT spends compiling byte code into native code partitioned by JIT thread.

Metric Dimensions

• thread: The thread ID associated with the work.

jvmstat_jit_compilation_count

This metric tracks the number of classes the JIT has compiled and potentially recompiled after determining either the initial byte code definition or re-interpreted machine code representation is suboptimal.

Metric Dimensions

• thread: The thread ID associated with the work.
