The software monitors server load and all the major services usually running on a Linux hosting server: apache, mysql, DNS, email, ftp, cPanel and more.
It checks the server status on every 0.5 seconds, which makes it the fastest monitoring solution available. Just to illustrate how much faster it is than other solutions: Nagios checks at least on 1 minute, and the cPanel inbuilt monitoring system on 5 minutes.
Additionally it automatically reacts when a server load is higher than normal or an unresponsive service is detected. Thus most of the common problems affecting the uptime of the web hosts are solved in less than a second without human intervention.
