uptime
A remote monitoring application using Node.js, MongoDB, and Twitter
...It lets users define checks for websites or endpoints, then tracks whether those targets are available over time. The application includes a web interface built with Twitter Bootstrap for managing checks and visualizing availability. Users can configure polling intervals, slow-response thresholds, alert thresholds, tags, and expected response patterns. It was designed as a self-hosted monitoring utility for teams that wanted visibility into uptime without relying entirely on external services. Since the repository is archived, it is best treated as a historical monitoring project or reference implementation rather than a modern production-ready service.
