Processes List
==============
Compact view:
.. image:: ../_static/processlist.png
Full view:
.. image:: ../_static/processlist-wide.png
Filtered view:
.. image:: ../_static/processlist-filter.png
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
-------------
.. image:: ../_static/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.
