Overview of @Scheduled methods (spring-boot-actuator)

We use @Scheduled annotation to schedule some tasks. But they are hidden at runtime and can be forgotten easily. It would be very nice to have an overview of all scheduled jobs and their cron values.

If spring-boot-actuator can provide an endpoint listing all scheduled methods we can monitor them via tools like spring-boot-admin (https://github.com/codecentric/spring-boot-admin/issues/432)

Thanks.

Here’s an example of the response from the new scheduledtasks endpoint:

}

Thanks. That worked. @Scheduled shows the method name in the /actuator/scheduledtasks. It would be great if ScheduledTaskRegistrar provided a way to specify the name of the scheduled task. When I used lambda with ScheduledTaskRegistrar, /actuator/scheduledtasks shows name of the lambda which is kinda not useful.
