= Enabled {jdgserver_name} server metrics

{jdgserver_name} exposes metrics in the endpoint `/metrics`.
By default, they are enabled.

To configure metrics in the {jdgserver_name} server, just enabled as shown in the XML below.

.infinispan.xml
[source,xml]
----
<infinispan>
    <cache-container statistics="true">
        <metrics gauges="true" histograms="false" />
    </cache-container>
</infinispan>
----

Using the {jdgserver_name} Operator in Kubernetes, metrics can be enabled by using a `ConfigMap` with a custom configuration.
It is shown below an example.

.ConfigMap

kind: ConfigMap

  name: cluster-config

        metrics:
          gauges: true
          namesAsTags: true
          histograms: false
          legacy: true
