How to detect:

Tasks fail without triggering alerts or appearing in logs, creating detection lag of 5-30 minutes via traditional log-based monitoring. Silent failures can affect 3-5% of tasks that vanish from broker without reporting status (orphaned tasks).

Recommended action:

Implement real-time WebSocket-based monitoring with sub-100ms latency. Enable orphan detection to catch tasks that disappear from broker. Configure alerts for >10 failures in 1 minute (critical) and >5 failures in 1 minute for payment tasks. Set up retry tracking to identify tasks that fail silently during retry attempts.
