java.lang.Object

de.codecentric.batch.web.JobMonitoringController

@RestController
 @RequestMapping(value="${batch.web.monitoring.base:/batch/monitoring}")
public class JobMonitoringController
extends Object

Controller for delivering monitoring information, like

• which jobs are deployed?
• which jobs are currently running on this machine?
• detailed information on any running or finished job.

The base url can be set via property batch.web.monitoring.base, its default is /batch/monitoring. There are four endpoints available:

1. Retrieving the names of deployed jobs
   {base_url}/jobs / GET
   On success, it returns a JSON array of String containing the names of the deployed jobs.
2. Retrieving the ids of JobExecutions running on this server
   {base_url}/jobs/runningexecutions / GET
   On success, it returns a JSON array containing the ids of the JobExecutions running on this server.
3. Retrieving the ids of JobExecutions running on this server for a certain job name
   {base_url}/jobs/runningexecutions/{jobName} / GET
   On success, it returns a JSON array containing the ids of the JobExecutions running on this server belonging to the specified job.
4. Retrieving the JobExecution
   {base_url}/jobs/executions/{executionId} / GET
   On success, it returns a JSON representation of the JobExecution specified by the id. This representation contains everything you need to know about that job, from job name and BatchStatus to the number of processed items and time used and so on.
   If the JobExecution cannot be found, a HTTP response code 404 is returned.
