By selecting a host template for the device, you have added a predefined package of graph templates and data queries to the host. This is a convenient way of reducing the administrative tasks of adding these manually through the provided drop-down lists. You will come back to templates later in the book, so you do not have to fully understand these right now.

Cacti displays performance data as graphs, therefore we are now going to add some basic graphs to the device which we have just added. The first graph which you are going to add is a simple ping graph. Let's go ahead and add the ping template to the host and later add the associated graph to the device.
