Performance Manager is a real-time performance monitor that allows users

hundreds of different system values, including CPU performance, memory
usage, disk transfers, file-system capacity, and network efficiency.
Thresholds can be set to alert you to correct a problem when it occurs,
commands can be run on multiple nodes from the graphical user interface,
and archives of data can be kept for high-speed playback or long-term
trend analysis.
