Class MicrometerSupport

  • All Implemented Interfaces:
    RestServiceSupport, Service

    public class MicrometerSupport
    extends HelidonRestServiceSupport
    Implements simple Micrometer support.

    Developers create Micrometer MeterRegistry objects and enroll them with MicrometerSupport.Builder, providing with each enrollment a Helidon Handler for expressing the registry's data in an HTTP response.

    Alternatively, developers can enroll any of the built-in registries represented by the MeterRegistryFactory.BuiltInRegistryType enum.

    Having enrolled Micrometer meter registries with MicrometerSupport.Builder and built the MicrometerSupport object, developers can invoke the registry() method and use the returned MeterRegistry to create or locate meters.
