  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.
