Class MetricsListener

java.lang.Object

org.springframework.batch.core.listener.StepExecutionListenerSupport

de.codecentric.batch.metrics.MetricsListener

All Implemented Interfaces:

org.springframework.batch.core.JobExecutionListener, org.springframework.batch.core.StepExecutionListener, org.springframework.batch.core.StepListener, org.springframework.core.Ordered

public class MetricsListener
extends org.springframework.batch.core.listener.StepExecutionListenerSupport
implements org.springframework.core.Ordered, org.springframework.batch.core.JobExecutionListener

This listener exports all metrics with the prefix 'counter.batch.{jobName}.{jobExecutionId}.{stepName} and all gauges with the prefix 'gauge.batch.{jobName}.{stepName}' to the Step- ExecutionContext without the prefix. All metrics and gauges are logged as well. For overriding the default format of the logging a component implementing MetricsOutputFormatter may be added to the ApplicationContext. Counters are cumulated over several StepExecutions belonging to one Step in one JobInstance, important for restarted jobs.
