- If you are only monitoring a few resources, you will only need a central server.
- If you are monitoring a large number of resources, spread the load across a distributed architecture.
In Centreon, the central server is the main console where you monitor resources. The central server allows you to:
- configure the monitoring of your whole infrastructure,
- monitor resources
- see what all your Centreon servers monitor (central server, remote servers and pollers), using its web interface.
A remote server is attached to a central server. Pollers can be attached to a remote server.
- A remote server monitors resources. It has a monitoring engine.
- It has a graphical interface, but no configuration menus.
- The resources it monitors are displayed in its interface, and in the interface of the central server it is attached to.
- A Centreon poller monitors resources. It has a monitoring engine.
- A poller has no graphical interface: the resources it monitors are displayed in the interface of the central server and of the remote server it is attached to.
