2.2 Nagios Overview Nagios is a host and service monitor designed to inform you of network problems before your technologists, radiologists or managers do. The monitoring daemon runs intermittent checks on hosts and services you specify using external "plugins" which return status informa-tion to Nagios .
These documents provide supporting documentation needed to successfully implement multi-tenancy with Nagios XI. Multi-Tenancy Overview Multi-tenancy allows administrators to configure Nagios XI in such a way that the following criteria can be met: A single Nagios XI instance can monitor hosts and services for multiple users (clients)
