Seiri guides
Background job monitoring
Background job monitoring is about workers that should keep ticking. When the last successful check-in is too old, Seiri alerts you — whether the worker crashed, stalled, or the scheduler forgot the job.

Pattern
Emit a heartbeat at the end of each successful unit of work (or on a fixed interval for long-lived workers). Pair with grace periods so brief jitter doesn’t page you.
FAQ
Does Seiri replace my queue dashboard?
No. It catches silence and missed schedules; your queue UI still shows depth and retries.
