Package com.vaadin.copilot

Class CopilotTimingLog

java.lang.Object

com.vaadin.copilot.CopilotTimingLog

public final class CopilotTimingLog
extends Object

In-memory ring buffer for Copilot startup/connection timing markers.

This is diagnostic scaffolding for investigating rare, intermittent slow loads that cannot be reproduced on demand. Markers are collected only when Copilot is running in development mode (Copilot.isDevelopmentMode()), so a slow load that already happened can be inspected afterwards without having to flip any per-logger flags first.

The frontend counterpart lives in shared/copilot-timing-log.ts; the collected server-side entries are exposed to the browser via TimingLogsHandler and can be read from the console with window.Vaadin.copilot.dumpTimingLogs().
