Sites are at the core of Vigilant. While many of the monitors can be configured separately from sites they can all be linked to a site.
A site is a place to group all the different monitors for a website and to quickly setup the monitors.
You can add a site by clicking on Sites in the menu and clicking the Add Site button in the top right.
Once you have added your site you can click edit and use the available monitor tabs to quickly enable monitors for this site.
Enabling the monitors will create the underlying monitor and link them to the site.
