Alerts are good at catching conditions someone knew to define. But many production problems begin as weak, scattered signals: intermittent retries, recurring warnings, partial failures, configuration drift, capacity pressure, and fallback paths quietly doing more work.
Each signal may be too small to page on. Retries hide the immediate failure. Dashboards stay green. No threshold fires. Meanwhile, customers are already experiencing slower requests, occasional errors, or degraded behavior.
Eventually the problem becomes loud enough for the existing stack to notice. By then, the routine fix has become an incident.
Tero continuously reads the signals nobody has time to watch, connects the evidence over time, and raises the issue while it is still small. The goal is not another alert. It is to fix production problems before they become fire drills.
