How do I check on the queue workers?
Helix Swarm uses a custom queue system to process events, provide notifications, and more. The queue system is required to handle the potentially large volume of events from a busy Helix Versioning Engine.
Check the status of the queue by making an HTTP request to
/queue/status. The response is formatted in JSON, and
looks like this:
{"tasks":0,"futureTasks":1,"workers":3,"maxWorkers":3,"workerLifetime":"595s"}
This response indicates that the queue has no current tasks, there is 1 task scheduled for processing later, there are 3 queue workers available, at most 3 workers are created, and queue workers run for at most 10 minutes before self-terminating.
A queue manager ensures that sufficient queue workers are available to
process items. If the queue manager has stopped for some reason, start a new
one by making an HTTP request to /queue/worker. No
response is provided for this request.
Note
A cron job should be setup to ensure that workers are running to process events. See Set up a recurring task to spawn workers.
