It supports Java, Clojure, Scala, JRuby, and anything else that runs on the JVM.
If you use Maven, you can simply reference the following assets:
- Original Client
- The Client
- groupId: io.prometheus
- artifactId: client
- version: 0.0.5
- Hotspot 'jvmstat/perfdata' Metrics
- groupId: io.prometheus.client.utility
- artifactId: jvmstat
- version: 0.0.5
- Hotspot VM Metrics
- groupId: io.prometheus.client.utility
- artifactId: hotspot
- version: 0.0.5
- Exposition Servlet - Transferring Metrics to Prometheus Servers
- groupId: io.prometheus.client.utility
- artifactId: servlet

- artifactId: simpleclient_servlet

- PushGateway support
- groupId: io.prometheus
- artifactId: simpleclient_pushgateway
- version: 0.0.5
- The Client
There are canonical examples defined in the class definition Javadoc of the client packages.
See the wiki for more information.
The client is canonically documented with Javadoc. Running the following will produce output local documentation in apidocs directories for you to read.
$ mvn package
If you use the Mavenized version of the Prometheus client, you can also instruct Maven to download the Javadoc and source artifacts.
Alternatively, you can also look at the generated Java Client Github Project Page, but the raw Javadoc in Java source in version control should be treated as the canonical form of documentation.
This suite is built and managed by Maven, and the artifacts are hosted on the Sonatype OSS Asset Repository.
All contributions to this library must follow, as far as practical, the prevalent patterns in the library for consistency and the following style guide: Google Java Style. Depending upon your development environment, you may be able to find an automatic formatter and adherence checker that follows these rules.
$ mvn compile
$ mvn test
Please note that tests on Travis may be unreliable due to the absence of installed Maven artifacts. Ensure that the current snapshot version is deployed to Sonatype OSS Repository.
These steps below are only useful if you are in a release engineering capacity and want to publicize these changes for external users. You will also need to have your local Maven setup correctly along with valid and public GPG key and adequate authorization on the Sonatype OSS Repository to submit new artifacts, be they staging or release ones.
You should read the Sonatype OSS Maven Repository Usage Guide before performing any of the following:
$ mvn clean deploy -DperformRelease=true
$ mvn release:clean -DperformRelease=true
$ mvn release:prepare -DperformRelease=true
$ mvn release:perform -DperformRelease=true
Documentation can also be released to the public via the Github Pages subproduct through the magic gh-pages branch for a Github project. Documentation is generated via the following command:
$ mvn javadoc:aggregate
It will need to be automatically merged into the gh-pages branch, but that is as simple as this:
$ git checkout master
$ mvn javadoc:aggregate
$ git checkout gh-pages
$ mv target/site/apidocs/ ./
$ git status
$ # Amend the branch as necessary.
$ git commit
$ git push
There is a Maven plugin to perform this work, but it is broken. The javadoc:aggregate step will emit documentation into target/site/apidocs. The reason that we use this aggregate step instead of bare javadoc is that we want one comprehensive Javadoc emission that includes all Maven submodules versus trying to manually concatenate this together.
Output documentation lives in the Java Client Github Project Page.
- All of the core developers are accessible via the Prometheus Developers Mailinglist.
