Introduction to the web interface¶
Centreon web interface is made up of several menus, each menu has a specific function:
- The Home menu enables access to the first home screen after logging in. It summarises the general status of the supervision.
- The Monitoring menu contains the status of all the supervised elements in real and delayed time via the viewing of logs and performance graphics.
- The Reporting menu serves to view, intuitively (via diagrams), the evolution of the supervision on a given period.
- The Configuration menu serves to configure all monitored objects and the supervision infrastructure.
- The Administration menu serves to configure the Centreon web interface and to view the general status of the servers.
Before going further¶
it is necessary update the server. To do this:
- Log in as a ‘root’ on the central server
- Enter this command
yum -y update
Allow the update to run fully and then restart the server in case of a kernel update.
Easy monitoring configuration¶
Centreon is great in itself, highly versatile and can be configured to fit the very specifics of your monitored infrastructure. However you might find useful to use Centreon IMP to get you started in minutes. Centreon IMP provides you Plugin Packs which are bundled configuration templates that highly reduce the time needed to properly monitor the most common services of your network.
Centreon IMP needs the technical components Centreon License Manager and Centreon Plugin Pack Manager to work.
When using Centreon ISO, installation of Centreon Plugin Pack Manager is very easy. You’ll see that Centreon License Manager will be installed too as a dependency.
$ yum install centreon-pp-manager
Once the packages installed, you need to enable the module in Centreon. So get to the Administration -> Extensions -> Modules page.
Install Centreon License Manager (dependency of Centreon Plugin Pack Manager) first.
Then install Centreon Plugin Pack Manager itself.
You’re now ready to got to Administration -> Extensions -> Plugin packs -> Setup. You’ll find there 6 free Plugin Packs to get you started. 5 more are available after free registration and 150+ if you subscribe to the IMP offer (more information on our website).
You can continue to configure your monitoring with Centreon IMP by following this guide.
