Nagios

Nagios (nagios.org) is a long-running open-source infrastructure monitoring and alerting platform. Checks hosts/services against defined states and fires alerts when thresholds are crossed.

Used at Uber as the alerting layer at scale alongside M3 for metrics observability during the 2013+ microservice build-out. (Source: sources/2024-03-14-highscalability-brief-history-of-scaling-uber)
