PRTG Network Monitor Unlimited - maintenance - unlimited sensors

More than 150,000 administrators rely on PRTG Network Monitor every day to monitor their LANs, WANs, servers, websites, appliances, URLs, and more. Network problems create business emergencies. When the network goes down, employees can't read emails.

PRTG Network Monitor runs on a Windows machine within your network, collecting various statistics from the machines, software, and devices which you designate. It also retains the data so you can see historical performance, helping you react to changes. PRTG comes with an easy-to-use web interface with point-and-click configuration. You can easily share data from it with non-technical colleagues and customers, including via live graphs and custom reports. This will let you plan for network expansion, see what applications are using most of your connection, and make sure that no one is hogging the entire network just to torrent videos.
