WHOWATCH(1)                          General Commands Manual                          WHOWATCH(1)

NAME
       whowatch - console, interactive, process and users monitoring tool.

DESCRIPTION
       Whowatch is an console, interactive users and process monitoring tool.  It displays infor-
       mation about the users currently logged on to the machine, in real-time.  Besides standard
       information  (login name, tty, host, user's process), the type of the connection (ie. tel-
       net or ssh) is shown.  Display of users command line can be switch to tty idle time.  Cer-
       tain user can be selected and his processes tree may be viewed as well as tree of all sys-
       tem processes. Tree may be displayed with additional  column  that  shows  owner  of  each
       process.  In the process tree mode SIGINT, SIGHUP, SIGTERM and SIGKILL signals can be sent
       to the selected process. Killing processes is just as simple and fun as deleting lines  on
       the screen.

       Whowatch  has no command line options or configuration file.  All actions are performed in
       real time by pressing following keys:

       Users list mode:

       'up' 'down'
              cursor movement

       'i'    toggle between user command line and idle time

       'c'    full command line on/off. Disabling full command line can save CPU  time.   It  can
              give you also some additional information about process executable.

       'enter'
              view selected user's processes tree.

       't'    all system processes (init tree)

       Tree mode:

       'up' 'down'
              cursor movement

       'enter'
              go back to users list

       'o'    show processes owners

       'c'    full  command  line  on/off. Disabling full command line can save CPU time.  It can
              give you also some additional information about process executable.

       'Ctrl-I'
              send INT signal to selected process

       'Ctrl-K'
              send KILL signal to selected process

       'Ctrl-U'
              send HUP signal to selected process

       'Ctrl-T'
              send TERM signal to selected process

PLUGINS
       Whowatch has ability to load plugin during program run.  Plugin prints information  inside
       details  window.   Plugins  gives flexibility: if some specific information about process,
       user or  system  is  needed  then  separate  program  could  be  written  to  obtain  such
       information.   Since  there  are  three kinds of deatils window (process, user and system)
       maximum three plugins can be loaded.  Whowatch has very simple API to write plugins.

FILES
       Program reads /var/log/wtmp, /var/run/utmp. Under Linux  program  also  reads  files  from
       /proc  directory. Without read access to these files whowatch funcionality will be limited
       or program will not even start.

SEE ALSO
       finger(1) ps(1), pstree(1), top(1), w(1), lsof(8), kill(1) killall(1)

BUGS
       Because lack of ut_pid in utmp and wtmp structures  in  *BSD  systems,  program  tries  to
       obtain  pid  of  a  login  shell by analyzing processes controlling terminal and processes
       names. Under some conditions it may lead to incorrect results ie. there will be  incorrect
       processes tree associated with user's session.
