PRTG has been instrumental in allowing us to setup real time active monitoring of all web servers and continually evaluate resource management and usage across boxes. With built in selectable sensors covering a vast array of areas you would be hard pressed to find areas not covered. PRTG was easy to setup and use with documentation online to follow as needed. We are currently using for limited purposes so still fall into the free range of sensors but are looking to expand in the future to more devices.

Upgrading the software is extremely easy. There is no need to do any command line it is all downloaded and installed locally with the PRTG upgrade wizard. You get a good amount of probes for a great price which really sold us above Solar Winds

PRTG Network Monitor is a reporting tool which enables Network administrators to keep a closer look on network devices. Device wise network bandwidth, usage protocol stats, availability, uptime and performances are presented as easily readable graphics in PRTG.
