THIS VERSION OF THE REPORTER HAS BEEN DEPRECATED

Please use the official reporter located here, as a part of the main kamon project: https://github.com/kamon-io/kamon

Note: New Relic still supports that official reporter; we have just moved it to the kamon-io organization to improve visibility for kamon users.

New Relic Kamon Reporter

Reports data generated by the Kamon Java agent to New Relic via the Telemetry SDK.

Release Process

Publish to Staging Repo

The staging release job is managed by CircleCI.

To stage the release simply submit and merge a PR to update the build.sbt file with the version to be released (e.g. version := "0.0.4").

Results of the job can be viewed here: https://app.circleci.com/github/newrelic/kamon-newrelic-reporter/pipelines

After the staging release job has run successfully it will publish the new artifact to a staging repository on Sonatype at: https://oss.sonatype.org/#stagingRepositories.

Manually Release Staging Repo

1. Find the staging repo on Sonatype, which should be named similar to comnewrelic-nnnn, and validate that the contents and version look correct.
2. If the contents look correct, select the staging repo and choose close, leaving a comment such as releasing 0.0.4.
3. When the staging repo is finished closing, select the staging repo and choose release, keeping the Automatically Drop checkbox checked, and leave a comment such as releasing 0.0.4.
4. Verify that the artifact was published on Maven Central at: https://repo1.maven.org/maven2/com/newrelic/telemetry/kamon-newrelic-reporter_2.13/

Post Release

Submit and merge a PR with the following:

• Update the build.sbt file with a snapshot of the next version to be released (e.g. version := "0.0.5-SNAPSHOT").
• Update the CHANGELOG with details of the new release:

  ## [0.0.4]
  - Miscellaneous bug fixes and tweaks

• Update the Usage example in the README with the newly released version (e.g. "com.newrelic.telemetry" %% "kamon-newrelic-reporter" % "0.0.4").
