Atop - System- and process-level monitor

Atop is an ASCII full-screen performance monitor similar to the 'top' command. For a given interval, it shows system-level activity related to the CPU, memory, swap, disks and network layers, and for every active process it shows the CPU utilization in system and user mode, the virtual and resident memory growth, priority, username, state, and exit code. It also shows process level activity for processes which finished during the last interval.

Atop shows only the active system-resources and processes, and only the deviations since the previous interval. Unfortunately, the standard kernel does not maintain counters about the number of disk and network accesses issued per process. Kernel patches will be made available to add these counters; the current version of atop can already display them.
