mp.metrics.appName

Passes the value of the _app tag from the application server to the application. This property is used to avoid metric name collisions when multiple applications are deployed to the runtime. It is defined through a microprofile-config.properties file in the META-INF directory of the application. The value of this tag is appended to the output of each metric that originates from that application.

In MicroProfile Metrics 5.0 and later, the _app tag that is defined in prior releases by the mp.metrics.appName MicroProfile Config property is designated as mp_app. In a MicroProfile Metrics 5.x environment, if the mp.metrics.appName property is defined, you must also define the mp.metrics.defaultAppName property. See the mp.metrics.defaultAppName property description for more information.

This value is read and evaluated during run time.

mp.metrics.appName=myApp

mp.metrics.defaultAppName

The value for this property is defined at the server level and is used along with the mp.metrics.appName property when you run in a MicroProfile Metrics 5.x environment. The value of the mp.metrics.defaultAppName property passes the value of the mp_app tag to metrics that are created on the server level.

This property is necessary to use with the mp.metrics.appName property due to the restriction introduced in MicroProfile Metrics 5.0 that metrics of the same name must contain the same set of tag names. Certain vendor metrics, such as servlet metrics, can create metrics in both the application and server context. The mp.metrics.appName property creates the mp_app tag for the servlet metrics that are created in the application context. However, without a similar tag value that is provided for servlet metrics that are created in the server context, a registration exception is thrown. The mp.metrics.defaultAppName property that is defined at the server level provides the necessary mp_app tag for metrics that are created at the server level.
