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 (RES divided by
|
|
the total RAM you have)
|
|
``VIRT`` Virtual Memory Size
|
|
|
|
The total amount of virtual memory used by the
|
|
process.
|
|
|
|
It includes all code, data and shared
|
|
libraries plus pages that have been swapped out
|
|
and pages that have been mapped but not used.
|
|
|
|
Most of the time, this is not a useful number.
|
|
``RES`` Resident Memory Size
|
|
|
|
The non-swapped physical memory a process is
|
|
using (what's currently in the physical memory).
|
|
``PID`` Process ID
|
|
``USER`` User ID
|
|
``THR`` Threads number of the process
|
|
``TIME+`` Cumulative CPU time used by the process
|
|
``NI`` Nice level of the process
|
|
``S`` Process status
|
|
|
|
The status of the process:
|
|
|
|
- ``R``: running or runnable (on run queue)
|
|
- ``S``: interruptible sleep (waiting for an event)
|
|
- ``D``: uninterruptible sleep (usually I/O)
|
|
- ``Z``: defunct ("zombie") process
|
|
- ``T``: traced by job control signal
|
|
- ``t``: stopped by debugger during the tracing
|
|
- ``X``: dead (should never be seen)
|
|
|
|
``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
|

Process filtering
|
|
-----------------
|
|
|
|
It's possible to filter the processes list using the ``ENTER`` key.
|
|
|
|
Filter syntax is the following (examples):
|
|
|
|
- ``python``: Filter processes name or command line starting with
|
|
*python* (regexp)
|
|
- ``.*python.*``: Filter processes name or command line containing
|
|
*python* (regexp)
|
|
- ``username:nicolargo``: Processes of nicolargo user (key:regexp)
|
|
- ``cmdline:\/usr\/bin.*``: Processes starting by */usr/bin*
|
|
|
|
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 for CPU and MEM percent values can be overwritten in the
|
|
configuration file under the ``[processlist]`` section. It is also
|
|
possible to define limit for Nice values (comma separated list).
|
|
For example: nice_warning=-20,-19,-18
