Mechanism

This exporter accesses to redis to aggregate queue status.

1. Collect name of queues via <namespace>:queues entry (by using SMEMBERS)
2. Get number of remained jobs for each queue via <namespace>:queue:<queue_name> entry (by using LLEN)

Note

This exporter also supports resque compatible job-queue engine (e.g. jesque).
