| /** |
| * Geode uses Micrometer for its metrics. Each Geode cache maintains a registry of all meters that |
| * instrument Geode code. Users can add sub-registries for various purposes. A key purpose for a |
| * sub-registry is to publish a cache's metrics to an external monitoring system. |
| * |
| * <p> |
| * The {@link org.apache.geode.metrics.MetricsSession MetricsSession} provides the ability to add |
| * and remove a meter registry for publishing metrics to external monitoring systems. |
| * |
| * <p> |
| * The {@link org.apache.geode.metrics.MetricsPublishingService MetricsPublishingService} defines |
| * a service that users can implement to be notified when a metrics session starts or stops. When |
| * a session starts, the service can add a meter registry to the session. When the session stops, |
| * the service should clean up any resources and remove its meter registry from the session. |
