MetricsApplicationListener

public MetricsApplicationListener(MetricsKey metricsKey)

Method Details

onPostEventBuild

public static AbstractMetricsKeyListener onPostEventBuild(MetricsKey metricsKey,
 CombMetricsCollector<?> collector)

Perform auto-increment on the monitored key, Can use a custom listener instead of this generic operation

Parameters:

metricsKey - Monitor key

collector - Corresponding collector

onFinishEventBuild

public static AbstractMetricsKeyListener onFinishEventBuild(MetricsKey metricsKey,
 MetricsPlaceValue placeType,
 CombMetricsCollector<?> collector)

To end the monitoring normally, in addition to increasing the number of corresponding indicators, use the introspection method to calculate the relevant rt indicators

Parameters:

metricsKey - Monitor key

collector - Corresponding collector

onErrorEventBuild

public static AbstractMetricsKeyListener onErrorEventBuild(MetricsKey metricsKey,
 MetricsPlaceValue placeType,
 CombMetricsCollector<?> collector)

Similar to onFinishEventBuild
