The widget monitors the task queue and the workers that process tasks in the background. It displays queue statistics, worker (consumer) information, and details of every task in the queue.
Displayed data
The widget has three main sections.
Queue statistics
The top of the widget displays four key metrics:
- Queue size — Total number of tasks in the queue.
- Pending tasks — Number of tasks waiting to be processed.
- Active workers — Number of active workers (consumers) processing tasks.
- Queued tasks — Total number of new and in-progress tasks.
Workers table
The table provides information about each active worker:
- Consumer name — Worker (consumer) identifier.
- Pending tasks — Number of tasks assigned to the worker and waiting to be processed.
- Idle time — Time since the worker’s last activity.
The table displays only active workers. Workers that are not processing tasks and have been inactive for more than five minutes are automatically hidden.
Tasks table
The table provides details about every task in the queue:
- Task UUID — Unique task identifier.
- Type — Task type, for example,
health_check. - Resource UUID — Identifier of the resource or entity associated with the task.
- Consumer — Name of the consumer processing the task.
- Idle time — Time since the task was delivered to the worker.
- Delivery time — Time when the task was delivered to the worker.
- Status — Current task status:
- New — The task has been added to the queue but has not yet been assigned to a worker.
- In progress — The task has been assigned to a worker and is being processed.
Configuration
The widget requires no additional configuration and works immediately after you add it to the dashboard.
