PERFMON(1)

NAME
perfmon - graphical display of general system statistics

SYNOPSIS
perfmon [ statistic ] ...

DESCRIPTION
perfmon provides a graphical display of the system-wide performance statistics and updates them approximately once a second. It should be executed from a graphics tool inside the SunView system. The time interval between updates can be adjusted by typing one of the following characters while the mouse is in the graphics subwindow:

s   Increase the interval by 0.05 seconds (slower by a little).

S   Increase the interval by one second (slower by a lot).

f   Decrease the interval by 0.05 seconds (faster by a little).

F   Decrease the interval by one second (faster by a lot).

R   Reset the interval to the standard 1.05 seconds.

In addition, typing:

H, h or ?
    List the characters that perfmon is listening for.

Q or q
    Cease executing perfmon.

If no statistic argument is given, perfmon displays all statistics. A tick is placed on the lines separating the graphs once every fifteen seconds (due to scheduling vagaries, these ticks may not be evenly spaced).
