JFR Datasource for Grafana

jfr-datasource

This demonstrates how a simple json data source can be used in Grafana to read the events of a JFR file

Usage

Build

This project uses Quarkus, which can produce a JAR to run in a JVM, or an executable native image.

To build a JAR:

mvn clean verify

To build a native image instead:

mvn -Pnative clean verify

Run the server, targeting a jfr file

If you built a JAR:

java -DjfrFile=<path-to-jfr> -jar ./server/target/server-1.0.0-SNAPSHOT-runner.jar

If you built a native image:

./server/target/server-1.0.0-SNAPSHOT-runner -DjfrFile=<path-to-jfr>

Run Grafana

• Add a SimpleJson data source
• Set the URL to: http://localhost:8080
• Create a panel that pulls from the data source and plots a timeseries
