Nagios Architecture
The following points are worth notable about Nagios architecture −
Nagios has server-agent architecture.
Nagios server is installed on the host and plugins are installed on the remote hosts/servers which are to be monitored.
Nagios sends a signal through a process scheduler to run the plugins on the local/remote hosts/servers.
Plugins collect the data (CPU usage, memory usage etc.) and sends it back to the scheduler.
Then the process schedules send the notifications to the admin/s and updates Nagios GUI.
