Camel Example Flight Recorder

Introduction

This example demonstrates how to integrate Camel with Java Flight Recorder which can be used to diagnose your JVM applications.

In JDK Mission Control (visualisation tool for flight recorder), you can browse Camel events which for example can help diagnose problems with slow startup of Camel routes.

How to run

You can run this example using

$ mvn camel:run

And then after Camel has been started up, a recording is saved to disk (current directory), where you can see from the logs the location of the file, such as:

Flight recorder recording saved: ./camel-recording13093057117733087947.jfr

You can then open this jfr file in JDK Mission Control and browse the information. In the Event Browser you can find the Camel Startup events, which can help pin-point to where Camel is slow to startup.

Note	The recording is started when Camel is bootstrapped, and therefore not from the very beginning of the JVM. To capture from the JVM beginning you can run java with -XX:StartFlightRecording.

Using logger instead of flight recorder

Instead of capturing a recording you can configure Camel to log the startup steps instead by setting

camel.main.startup-recorder = logging

In the application.properties file.
