For instance, the network monitoring tool determines how much bandwidth is consumed by specific devices and applications and identifies the bottleneck sources.

A server monitoring tool measures the performance of your web, database, mail, and file servers and issues instant alerts if something is off. The cloud management service helps you access your devices from anywhere. You can also track the performance of your operating systems, be it Linux, Windows, or Mac OS X.
