Uses netatop kernel module to monitor TCP & UDP and network bandwidth.Includes disk I/O and network utilization.Will add or remove columns as the size of the display window changes.
Highlights critical resources using colors (red).Accumulates resource usage for all processes and users with the same name.Monitors threads within processes & ignores unused processes.Shows resource usage of ALL processes, even those that are closed/completed.One feature I really like is that atop will stay active in the background for long-term server analysis (up to 28 days by default). Atop is an ASCII full-screen performance monitor which can log and report the activity of all server processes.
