Method Detail

setupBackend

public static BackendRegistry setupBackend(MicrometerMetricsOptions options,
                                           io.micrometer.core.instrument.MeterRegistry meterRegistry)

Create a new backend registry, containing a micrometer registry, initialized with the provided options. If a registry already exists with the associated name, it is just returned without any effect.

Parameters:

options - micrometer options, including configuration related to the backend. Should be a subclass of MicrometerMetricsOptions (ex: VertxInfluxDbOptions, VertxPrometheusOptions). If the class is not recognized, a NoopBackendRegistry will be returned.

Returns:

the created (or existing) BackendRegistry

getDefaultNow

public static io.micrometer.core.instrument.MeterRegistry getDefaultNow()

Get the default micrometer registry. May return null if it hasn't been registered yet or if it has been stopped.

Returns:

the micrometer registry or null

getNow

public static io.micrometer.core.instrument.MeterRegistry getNow(String registryName)

Get the micrometer registry of the given name. May return null if it hasn't been registered yet or if it has been stopped.

Parameters:

registryName - the name associated with this registry in Micrometer options

Returns:

the micrometer registry or null

stop

public static void stop(String registryName)

Stop (unregister) the backend registry of the given name. Any resource started by this backend registry will be released (like running HTTP server)

Parameters:

registryName - the name associated with this registry in Micrometer options

registerMatchers

public static void registerMatchers(io.micrometer.core.instrument.MeterRegistry registry,
                                    Set<Label> enabledLabels,
                                    List<Match> matches)
