Enabling the Use of Coherence MP Health

To use Coherence MP Health, you should first declare it as a dependency in the project’s pom.xml file.

You can declare Coherence MP Health as follows:

<dependency>
    <groupId>${coherence.groupId}</groupId>
    <artifactId>coherence-mp-health</artifactId>
    <version>${coherence.version}</version>
</dependency>

Where:

• ${coherence.groupId} is the Maven group ID for the Coherence edition being used: com.oracle.coherence for the commercial edition or com.oracle.coherence.ce for the community edition.
• ${coherence.version} is the version of Coherence you are using.

After the module becomes available in the class path, the Coherence HealthCheck producer CDI bean is automatically discovered and registered as a MicroProfile health check provider. The Coherence health checks then become available through any health endpoints served by the application and is included in started, readiness, and liveness checks.
