  title: Nagios XI REST Config CPU API
  description: 'Built-in REST API for Nagios XI, the commercial enterprise distribution of

    Nagios. The API is split into three sections: Objects (read-only backend for

    hosts, services, contacts, host groups, etc.), Config (admin-only writes for

    hosts and services), and System (admin-only commands such as apply

    configuration, scheduled downtime, status). Responses are returned as JSON

    when `pretty=1` or by default. Authentication uses a per-user Nagios XI API

    key passed via the `apikey` query parameter.
