Yabeda::DelayedJob

Built-in metrics for DelayedJob background workers monitoring out of the box! Part of the yabeda suite.

Metrics

Works as the DelayedJjob plugin and provides following metrics:

• jobs_enqueued_total - the counter of enqueued jobs (segmented by queue/worker)
• jobs_failed_total/jobs_errored_total - the counter of failed/errored jobs (segmented by queue/worker/error)
• jobs_waiting_count - the number of jobs are waited for execution, queue size (segmented by queue).
• queue_latency - the queue latency - difference in seconds since the oldest job was enqueued (segmented by queue)
• job_runtime - the histogram of job running time (in seconds, segmented by queue, worker)
• running_job_runtime - the running time of currently executed job (segmented by queue, worker). Helps to determine long running jobs.
