Resources monitored: CPU, memory, file cache, hard and soft page faults, disk IO, network IO. Shows topmost processes fitting within the window size. Optionally select only processes matching a given user, PID, or program name. Select and kill an errant process. 

  • Overall system and top process resources are shown on one page.
  • CPU, memory, disk I/O, network I/O, and page faults are monitored.
  • The highest ranked processes fitting in the window are shown.
  • Minimal jumping around between samples (easy to follow a process).
  • Process rank is a weighted sum of recent CPU, hard page faults, and disk I/O.
  • Filter processes by user, PID, or program name.
  • Run as root via toolbar button (after password entry).
