XPERFMON(1)

NAME
xperfmon - X window system Unix performance monitoring tool

SYNOPSIS
xperfmon option [ option ] [ host:display ]

DESCRIPTION
This program allows you to monitor the performance of Unix on a machine. The information will be plotted graphically on a window. The possible options are user cpu time (user), system cpu time (system), idle cpu time (idle), free memory (free), disk transfers (disk), interrupts (interrupts), input packets (input), output packets (output), collision packets (collision). Any or all of these options can be specified at once. By default, xperfmon displays all of these statistics.

-bd color
    Specify the border color. On monochrome displays, should be ``white'', ``black'', or ``gray''; gray is the default.

-bg color
    Specify the background color. On monochrome displays, should be ``white'' or ``black''; black is the default.

-bw pixels
    Specify the width in pixels of the border around the xperfmon window. The default value is 3 pixels.

-fg color
    Specify the graph color. On monochrome displays, should be ``white'' or ``black''; white is the default.

-fn fontname
    The hostname will be displayed in the specified font (if none is specified, this defaults to 6x10).

-hl color
    Specify the hostname and scale line color; the default is to make it the same as the graph color.

-rv Cause xperfmon to produce all output in black-on-white instead of white-on-black.

-fw Cause xperfmon to produce all output in white-on-black instead of black-on-white.

-scale integer
    Specify the minimum number of divisions on the graph (default 1). xperfmon is free to use more divisions if the load gets too high to display, but it will never use fewer divisions than this.

-u seconds
    Set the update rate.

=geometry
    Allows you to position the window on the screen. See X(1) for a full description of geometry specifications.

[host]:[display]
    Normally, xperfmon gets the host and display number to use from the environment variable ``DISPLAY''. Either or both can be specified with this option. host specifies which machine to create the xperfmon window on, and display specifies the display number. For example, ``mit-grape-nehi:0'' creates an xperfmon on display 0 on machine mit-grape-nehi. Either value can be defaulted by omission but `:' is necessary to specify one or both.
