Nagios

Nagios is a family of open-source and commercial IT infrastructure monitoring tools, including Nagios Core (the original open-source monitoring engine), Nagios XI (the commercial enterprise distribution), Nagios Fusion, Nagios Log Server, and Nagios Network Analyzer, used to monitor hosts, services, networks, applications, and metrics with alerting and reporting. Nagios Core itself has no central HTTP API; Nagios XI ships a built-in REST API (typically reached at https://{nagios-xi-host}/nagiosxi/api/v1/) for reading, writing, deleting, and updating monitoring configuration and status. The Nagios XI API is authenticated via a per-user API key passed as a query parameter or header. Passive check results can also be submitted via NRDP (HTTP, JSON/XML) or NSCA (encrypted TCP, port 5667), and the NCPA cross-platform agent exposes a hierarchical REST API on port 5693.
