Enabling the MicroProfile metrics API

To configure the Liberty server to run an application that is enabled for the MicroProfile metrics API, you must set the feature for the server.

Open Liberty Documentation for the MicroProfile Metrics feature versions 2.0 and later is available on the Open Liberty website.

Procedure

  1. Configure the feature. Add the mpMetrics-1.0 to the feature manager in the server.xml file.
    The mpMetrics-1.0 feature requires also that you secure the REST API. The following example illustrates a basic security setup. MicroProfile metrics use the default keystore to secure the endpoint.
    
<featureManager>
  <feature>mpMetrics-1.0</feature>
</featureManager>

<quickStartSecurity userName="theUser" userPassword="thePassword"/>
<keyStore id="defaultKeyStore" password="Liberty"/>

    Liberty can be configured to support the MicroProfile 1.0 features by setting microProfile-1.0 in the server.xml file. However, the MicroProfile metrics API was produced after the MicroProfile 1.0 release and is not made available using that feature.

  2. Use the org.eclipse.microprofile.metrics Java package, included in the mpMetrics-1.0 feature, to instrument your application.
