- =======================
- List of Worker Events
- =======================
- This is the list of events sent by the worker.
- The monitor uses these to visualize the state of the cluster.
- .. contents::
- :local:
- Task Events
- ===========
- * task-received(uuid, name, args, kwargs, retries, eta, hostname, timestamp)
- Sent when the worker receives a task.
- * task-started(uuid, hostname, timestamp)
- Sent just before the worker executes the task.
- * task-succeeded(uuid, result, runtime, hostname, timestamp)
- Sent if the task executed successfully.
- Runtime is the time it took to execute the task using the pool.
- (Time starting from the task is sent to the pool, and ending when the
- pool result handlers callback is called).
- * task-failed(uuid, exception, traceback, hostname, timestamp)
- Sent if the execution of the task failed.
- * task-revoked(uuid)
- Sent if the task has been revoked (Note that this is likely
- to be sent by more than one worker)
- * task-retried(uuid, exception, traceback, hostname, delay, timestamp)
- Sent if the task failed, but will be retried in the future.
- (**NOT IMPLEMENTED**)
- Worker Events
- =============
- * worker-online(hostname, timestamp)
- The worker has connected to the broker and is online.
- * worker-heartbeat(hostname, timestamp)
- Sent every minute, if the worker has not sent a heartbeat in 2 minutes,
- it's considered to be offline.
- * worker-offline(hostname, timestamp)
- The worker has disconnected from the broker.
