NAME

xmeter - rstat display for X

SYNOPSIS

xmeter [-toolkitoption ...] [-option ...] [-stat] hosts ...

DESCRIPTION

Xmeter displays a periodically updating histogram of the system statistics gathered by rstat(3) for the specified hosts. Meters can be displayed in a vertical, horizontal or rectangular arrangement. As statistics range between 4 user defineable levels (OK, WARN, ERROR or FATAL), the background, foreground, highlight, border and internal border colors, and the background bitmap of each meter can be changed.

Xmeter uses the StripChart widget of the Athena Widget Set to graph each statistic. StripCharts automatically scale the graph as the value varies, by drawing a number of horizontal lines across the StripChart. Each line represents an increment of a user settable value. For example, if the statistic being graphed is number of pages paged in per second, and the scale is set to 10, then each horizontal line would represent 10 pages per second. Each time a graph is updated, xmeter will examine the current value of the statistic and the current scale. As the number of scale lines increases above wlevel and elevel the background colors and bitmaps of each meter are modified as specified. The current scale value can be examined by clicking any mouse button while the mouse pointer is in the StripChart. If the host is down the time it's been down will also be displayed.

Each meter has its own label displaying the host name and statistics name. The statistic being graphed may be modified while xmeter is running by moving the mouse pointer into the label part of a meter, clicking any mouse button, and sliding down to the desired stat. This menu also contains a quit option to exit xmeter.

BUGS

When a host doesn't respond it can sometimes take a while for the labels in the menubuttons to update.

The width and height of the stripchart widgets need to be initialized to a non zero value or the error "Widget has zero width and/or height" will be printed by the X toolkit. This can be done by the user or in the application defaults file. The supplied application defaults file initializes width and height to 80.
