Class MetricsHandler

java.lang.Object

kanela.agent.bootstrap.metrics.MetricsHandler

public final class MetricsHandler
extends java.lang.Object

MetricsHandler provides methods for creating and manipulating metrics from instrumented bytecode.

MetricsHandler avoids tight coupling with the concrete trace API through the MetricsHandler interface.

Both MetricsHandler and MetricsProvider are loaded by the bootstrap classloader so that they can be used from classes loaded by the bootstrap classloader. A concrete implementation of MetricsProvider will be loaded by the system classloader. This allows for using the same metrics API as the instrumented application.

MetricsHandler is implemented as a static class to allow for easy and fast use from instrumented bytecode.
