This is part of the link:{links_observability_metrics-for-troubleshooting_url}[{links_observability_metrics-for-troubleshooting_name}] {section}.

== Prerequisites

* Metrics need to be enabled for {project_name}. Follow the link:{links_observability_configuration-metrics_url}[{links_observability_configuration-metrics_name}] {section} for more details.
* A monitoring system collecting the metrics.

== Metrics

:jgrp_application: {project_name}
:clustered_caches: true

Deploying multiple {project_name} nodes allows the load to be distributed amongst them, but this requires communication between the nodes.
This section describes metrics that are useful for monitoring the communication between {project_name} in order to identify possible faults.

NOTE: This is relevant only for single-cluster deployments.
When multiple clusters are used, as described in link:{links_high-availability_multi-cluster-introduction_url}[{links_high-availability_multi-cluster-introduction_name}], {project_name} nodes are not clustered together and therefore there is no communication between them directly.
