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.
