Class ObservabilityDevToolsHandler

java.lang.Object

com.vaadin.observability.micrometer.devtools.ObservabilityDevToolsHandler

All Implemented Interfaces:

com.vaadin.base.devserver.DevToolsMessageHandler

public class ObservabilityDevToolsHandler
extends Object
implements com.vaadin.base.devserver.DevToolsMessageHandler

Dev-mode bridge between the live Micrometer MeterRegistry and the Vaadin Copilot metrics panel.

Discovered via the Java ServiceLoader by Flow's dev-tools server (see META-INF/services). On request from the panel it snapshots every vaadin.* meter and sends it to the browser over the shared dev-tools websocket. This is a developer-only convenience view; it has no effect in production where the dev-tools connection does not exist.
