lookoutstall
Lookoutstall is a term used in discussions of software reliability to describe a combined monitoring-and-throttle mechanism intended to curb cascading failures during periods of high load. The word blends look out, meaning continuous surveillance and anomaly detection, with stall, meaning deliberate pausing or throttling of workstreams. There is no formal standards body for the term, and definitions vary between organizations.
In practice, a lookoutstall system aggregates metrics such as request latency, error rates, queue depth, and
Use cases for lookoutstall include surge control in microservices, protection of downstream systems from overload, and
Design considerations include ensuring non-disruptive behavior under normal conditions, avoiding cascading stalls due to monitoring failures,
