We've completed a major overhaul of the SimpleWorker interface and it is now live. The new interface is reorganized and redesigned for a much better user experience allowing you to manage and monitor your workers/jobs more effectively. Here are some sample screens:
Analytics showing real-time activity (jobs in queue and jobs running) as well as jobs, duration, and errors over time
See high level activity across all your worker classes
View status of each job along with the log and this view also you to cancel queued/running jobs and retry failed jobs
There's a lot more, but this should give you a little taste. There is simply no better way to manage your background jobs than with SimpleWorker.
