Time for action – creating a new device in Cacti
Login as an admin user to your new Cacti installation.
Click on the Devices link under the Management menu. This will open a table with all devices added so far. For a new installation there should only be the localhost device showing its status as Up.
On the top right of the new page click on Add. This is the default position for this Add link.
You will now be presented with the Devices [new] screen. Have a look at this screen and make yourself comfortable with the different fields.
Enter a Description and Hostname (or IP address).
If you add an SNMP-enabled device, select SNMP as the Downed Device Detection method. Otherwise select Ping. When selecting Ping you can choose the protocol type and port to use.
Enter the SNMP community and select the correct version (some additional fields will show up when you choose SNMP Version 3). If the device is not SNMP compatible, you can select Not used.
You can also add some notes. Click on the Create button...
