Scheduled Tasks (scheduledtasks)

The scheduledtasks endpoint provides information about the application’s scheduled tasks.

Retrieving the Scheduled Tasks

To retrieve the scheduled tasks, make a GET request to /actuator/scheduledtasks, as shown in the following curl-based example:

$ curl 'http://localhost:8080/actuator/scheduledtasks' -i -X GET

The resulting response is similar to the following:

HTTP/1.1 200 OK
Content-Type: application/vnd.spring-boot.actuator.v3+json
Content-Length: 1222
