Processes List

Compact view:

Full view:

Filtered view:

The process view consists of 3 parts:

  • Processes summary
  • Monitored processes list (optional)
  • Processes list

The processes summary line displays:

  • Tasks number (total number of processes)
  • Threads number
  • Running tasks number
  • Sleeping tasks number
  • Other tasks number (not running or sleeping)
  • Sort key

By default, or if you hit the a key, the processes list is automatically sorted by:

  • CPU: if there is no alert (default behavior)
  • CPU: if a CPU or LOAD alert is detected
  • MEM: if a memory alert is detected
  • DISK I/O: if a CPU iowait alert is detected

The number of processes in the list is adapted to the screen size.

Columns display

CPU%

% of CPU used by the process

If Irix/Solaris mode is off, the value is divided by logical core number

MEM% % of MEM used by the process
VIRT

Virtual Memory Size

The total amount of virtual memory used by the process

RES

Resident Memory Size

The non-swapped physical memory a process is using

PID Process ID
USER User ID
NI Nice level of the process
S

Process status

The status of the process:

  • R: running
  • S: sleeping (may be interrupted)
  • D: disk sleep (may not be interrupted)
  • T: traced/stopped
  • Z: zombie
TIME+ Cumulative CPU time used by the process
R/s Per process I/O read rate in B/s
W/s Per process I/O write rate in B/s
COMMAND

Process command line or command name

User can switch to the process name by pressing on the '/' key

Extended info

../_images/processlist-top.png

In standalone mode, additional information are provided for the top process:

CPU affinity Number of cores used by the process
Memory info

Extended memory information about the process

For example, on Linux: swap, shared, text, lib, data and dirty

Open The number of threads, files and network sessions (TCP and UDP) used by the process
IO nice The process I/O niceness (priority)

The extended stats feature can be enabled using the --enable-process-extended option (command line) or the e key (curses interface).

Note

Limit values can be overwritten in the configuration file under the [process] section.
