Systemometer

Systemometer is a freeware monitoring tool that shows system performance and resources in a spider chart. Different shapes of monitoring polygon draw visual patterns associated with normal or critical system states. This snapshot view helps to read the overall system status at a glance. Systemometer records the history of counter values to the log file in either HTML or CSV format. It can be also configured to run as a screen saver.
