     151Nagios servers can be used in a hierarchy, where there is 1 master server and 2 or more slave servers. The master server runs the web interface, handles notifications, performance data etc. The slave servers schedule and execute checks and submit the check results (via NSCA) to the master server. Each slave server runs (a subset of the) checks against (a subset of the) nodes. The master server receives the results for all services and all hosts.
