9 Whowatch is an console, interactive users and process monitoring tool.
10 It displays information about the users currently logged on to the
11 machine, in real-time. Besides standard information (login name, tty,
12 host, user's process), the type of the connection (ie. telnet or ssh)
13 is shown. Display of users command line can be switch to tty idle
14 time. Certain user can be selected and his processes tree may be
15 viewed as well as tree of all system processes. Tree may be displayed
16 with additional column that shows owner of each process. In the
17 process tree mode SIGINT, SIGHUP, SIGTERM and SIGKILL signals can be
18 sent to the selected process. Killing processes is just as simple and
19 fun as deleting lines on the screen.
20
21 Whowatch has no command line options or configuration file. All
22 actions are performed in real time by pressing following keys:
23
24 Users list mode:
25
26 'up' 'down'
27 cursor movement
28
29 'i' toggle between user command line and idle time
30
31 'c' full command line on/off. Disabling full command line can save
32 CPU time. It can give you also some additional information
33 about process executable.
34
35 'enter'
36 view selected user's processes tree.
37
38 't' all system processes (init tree)
39
40 Tree mode:
41
42 'up' 'down'
43 cursor movement
44
45 'enter'
46 go back to users list
47
48 'o' show processes owners
49
50 'c' full command line on/off. Disabling full command line can save
51 CPU time. It can give you also some additional information
52 about process executable.
53
54 'Ctrl-I'
55 send INT signal to selected process
56
57 'Ctrl-K'
58 send KILL signal to selected process
59
60 'Ctrl-U'
61 send HUP signal to selected process
62
63 'Ctrl-T'
64 send TERM signal to selected process
65
66
68 Whowatch has ability to load plugin during program run. Plugin prints
69 information inside details window. Plugins gives flexibility: if some
70 specific information about process, user or system is needed then
71 separate program could be written to obtain such information. Since
72 there are three kinds of deatils window (process, user and system)
73 maximum three plugins can be loaded. Whowatch has very simple API to
74 write plugins.

80 Program reads /var/log/wtmp, /var/run/utmp. Under Linux program also
81 reads files from /proc directory. Without read access to these files
82 whowatch funcionality will be limited or program will not even start.
83
84
86 finger(1) ps(1), pstree(1), top(1), w(1), lsof(8), kill(1) killall(1)
87
88
90 Because lack of ut_pid in utmp and wtmp structures in *BSD systems,
91 program tries to obtain pid of a login shell by analyzing processes
92 controlling terminal and processes names. Under some conditions it may
93 lead to incorrect results ie. there will be incorrect processes tree
94 associated with user's session.
