Method Details

from

public BUILDER from(MetricsObserverConfig prototype)

Update this builder from an existing prototype instance. This method disables automatic service discovery.

Parameters:

prototype - existing prototype to update this builder from

Returns:

updated builder instance

from

public BUILDER from(MetricsObserverConfig.BuilderBase<?,?> builder)

Update this builder from an existing prototype builder instance.

Parameters:

builder - existing builder prototype to update this builder from

Returns:

updated builder instance

config

public BUILDER config(Config config)

Update builder from configuration (node of this type). If a value is present in configuration, it would override currently configured values.

Specified by:

config in interface Prototype.ConfiguredBuilder<BUILDER extends MetricsObserverConfig.BuilderBase<BUILDER,PROTOTYPE>,PROTOTYPE extends MetricsObserverConfig>

Overrides:

config in class ObserverConfigBase.BuilderBase<BUILDER extends MetricsObserverConfig.BuilderBase<BUILDER,PROTOTYPE>,PROTOTYPE extends MetricsObserverConfig>

Parameters:

config - configuration instance used to obtain values to update this builder

Returns:

updated builder instance

endpoint

public BUILDER endpoint(String endpoint)

Parameters:

endpoint -

Returns:

updated builder instance

See Also:

• endpoint()

metricsConfig

public BUILDER metricsConfig(MetricsConfig metricsConfig)

Assigns MetricsSettings which will be used in creating the MetricsSupport instance at build-time.

Parameters:

metricsConfig - the metrics settings to assign for use in building the MetricsSupport instance

Returns:

updated builder instance

See Also:

• metricsConfig()

metricsConfig

public BUILDER metricsConfig(Consumer<MetricsConfig.Builder> consumer)

Assigns MetricsSettings which will be used in creating the MetricsSupport instance at build-time.

Parameters:

consumer - consumer of builder for the metrics settings to assign for use in building the MetricsSupport instance

Returns:

updated builder instance

See Also:

• metricsConfig()

metricsConfig

public BUILDER metricsConfig(Supplier<? extends MetricsConfig> supplier)

Assigns MetricsSettings which will be used in creating the MetricsSupport instance at build-time.

Parameters:

supplier - supplier of the metrics settings to assign for use in building the MetricsSupport instance

Returns:

updated builder instance

See Also:

• metricsConfig()

clearMeterRegistry

public BUILDER clearMeterRegistry()

Clear existing value of this property.

Returns:

updated builder instance

See Also:

• meterRegistry()

meterRegistry

public BUILDER meterRegistry(MeterRegistry meterRegistry)

If you want to have multiple meter registries with different endpoints, you may create them using

     MeterRegistry meterRegistry = MetricsFactory.getInstance()
             .createMeterRegistry(metricsConfig);
     MetricsFeature.builder()
             .meterRegistry(meterRegistry) // further settings on the feature builder, etc.

where metricsConfig in each case has different settings.

If this method is not called, MetricsFeature would use the shared instance as provided by MetricsFactory.globalRegistry().

Parameters:

meterRegistry - meterRegistry to use in this metric support

Returns:

updated builder instance

See Also:

• meterRegistry()

endpoint

public String endpoint()

Returns:

the endpoint

metricsConfig

public MetricsConfig metricsConfig()

Assigns MetricsSettings which will be used in creating the MetricsSupport instance at build-time.

Returns:

the metrics config

meterRegistry

public Optional<MeterRegistry> meterRegistry()

If you want to have multiple meter registries with different endpoints, you may create them using

     MeterRegistry meterRegistry = MetricsFactory.getInstance()
             .createMeterRegistry(metricsConfig);
     MetricsFeature.builder()
             .meterRegistry(meterRegistry) // further settings on the feature builder, etc.

where metricsConfig in each case has different settings.

If this method is not called, MetricsFeature would use the shared instance as provided by MetricsFactory.globalRegistry().

Returns:

the meter registry

config

public Optional<Config> config()

If this instance was configured, this would be the config instance used.

Overrides:

config in class ObserverConfigBase.BuilderBase<BUILDER extends MetricsObserverConfig.BuilderBase<BUILDER,PROTOTYPE>,PROTOTYPE extends MetricsObserverConfig>

Returns:

config node used to configure this builder, or empty if not configured

toString

public String toString()

Overrides:

toString in class ObserverConfigBase.BuilderBase<BUILDER extends MetricsObserverConfig.BuilderBase<BUILDER,PROTOTYPE>,PROTOTYPE extends MetricsObserverConfig>

preBuildPrototype

protected void preBuildPrototype()

Handles providers and decorators.

Overrides:

preBuildPrototype in class ObserverConfigBase.BuilderBase<BUILDER extends MetricsObserverConfig.BuilderBase<BUILDER,PROTOTYPE>,PROTOTYPE extends MetricsObserverConfig>

validatePrototype

protected void validatePrototype()

Validates required properties.

Overrides:

validatePrototype in class ObserverConfigBase.BuilderBase<BUILDER extends MetricsObserverConfig.BuilderBase<BUILDER,PROTOTYPE>,PROTOTYPE extends MetricsObserverConfig>
