JFR Tools

StatsMaker

StatsMaker is a tool that reads a JFR recording file and generates statistics about the amount of metric and event data that is sent by the JFR daemon after processing the recording.

Build the jfr-tools jar

From the project root run:
./gradlew build

The generated jfr-tools jar can be found at:
newrelic-jfr-core/jfr-tools/build/libs/jfr-tools-1.2.0-SNAPSHOT.jar

Usage

  1. First you’ll need to generate a JFR recording file to process with the StatsMaker.
  2. Set your APM license key: export INSIGHTS_INSERT_KEY=123xyz
  3. Run the jfr-tools jar with the JFR recording file: java -jar jfr-tools-1.2.0-SNAPSHOT.jar </absolute/path/to/jfr/recording/file>

Output

StatsMaker will generate output similar to the following indicating the amount of metric and event data sent to New Relic.
