Class RegistryFactory

java.lang.Object
io.helidon.microprofile.metrics.RegistryFactory
public class RegistryFactory extends Object
Micrometer-specific implementation of a registry factory, created automatically whenever a new MeterRegistry is created by a metrics provider.

Note: Formerly, an instance of this class could be updated with new configuration information after it had been initialized as described in Github issue #360. This version, though, is instantiated once per new meter registry, with the intent that only one meter registry will every be created in a production server.

The getInstance(io.helidon.metrics.api.MeterRegistry) method creates a new instance and saves it for retrieval via getInstance(). The create(io.helidon.metrics.api.MeterRegistry) method creates a new instance but does not record it internally.
