1.1 deraadt 47: .Sh DESCRIPTION
1.13 aaron 48: .Nm
1.73 jmc 49: displays various system statistics in a screen-oriented fashion
50: using the
51: .Xr curses 3
52: screen display library.
1.1 deraadt 53: .Pp
54: While
1.13 aaron 55: .Nm
1.86 lum 56: is running, the screen is divided into different areas.
57: The top line displays the current number of users, the
58: three system load average figures over the last 1, 5, and
59: 15 minute intervals, and the system time.
1.73 jmc 60: The bottom line of the screen is reserved for
61: user input and error messages.
62: The information displayed in the rest of the screen
63: comprises a
64: .Em view ,
65: and is the main interface for
1.76 jmc 66: displaying different types of system statistics.
1.73 jmc 67: The
68: .Ic vmstat
69: view is the default.
1.77 jmc 70: .Pp
71: Certain information may be discarded when the screen size is
72: insufficient for display.
73: For example, on a machine with 10 drives the
74: .Ic iostat
75: bar graph displays only 3 drives on a 24 line terminal.
1.76 jmc 76: .\".Pp
77: .\"Input is interpreted at two different levels.
78: .\"A
79: .\".Dq global
80: .\"command interpreter processes all keyboard input.
81: .\"If this command interpreter fails to recognize a command, the
82: .\"input line is passed to a per-display command interpreter.
83: .\"This allows each display to have certain display-specific commands.
