This application will monitor, notify, and log the performance of NT/2000 computers. It groups each computer into the four major subsystems (CPU, memory, disk, and network) in an easy-to-use interface. It doesn't require any agents to be installed or run on the remote computers. Its unique feature is that it notifies only when the average value remains above a Threshold for a certain period of time, not just when it exceeds the threshold. Runs as a service without needing manual monitoring. An unlimited amount of servers can be viewed from the user interface. The product is divided into Versions that allow the computer running Performance Sentinel to monitor up to 1, 5, 10, or an unlimited amount of NT/2000 computers.
