Network monitoring refers to the monitoring of an entire network environment. Its goal is to allow sysadmins to work in a better, quicker, and more efficient manner. Network monitoring focuses on parameters such as bandwidth consumption and the availability of network devices.
Some of the monitored devices include the local and Internet-based systems in an IT environment, such as databases, applications, clouds, servers, and network infrastructures. Network monitoring allows admins to ensure their networks run smoothly, effectively, and free of errors.
The mere implementation of a network monitor is not enough. The key to effective network monitoring in real time is to ensure that your tool has been configured to monitor your network's “vital signs”: availability, speed, and usage.
Downtime and malfunctions can cause the performance of the entire company to suffer. At the same time, IT managers are under more and more pressure. They’re forced to act quickly but often don’t know where the problem lies. Here’s how PRTG helps IT managers get a handle on their network:

In PRTG, “sensors” are the basic monitoring elements. One sensor usually monitors one measured value in your network, for example the traffic of a switch port, the CPU load of a server, or the free space on a disk drive. On average, you need about 5-10 sensors per device or one sensor per switch port.
