xrload(1) — (X Window System Utilities)

NAME

xrload − X window system remote load average display

SYNOPSIS

xrload[-toolkitoption ...] [-scale integer] [-update seconds] [-ratio integer] [-ignore] [hostname ... ]

DESCRIPTION

xrload displays the system load averages for the hosts specified as arguments. It creates a grid of windows in which the load average for each host is represented as a bar graph with multiple divisions, and updates these windows on a regular basis. Each division represents one unit of load average. (A load of 2 units indicates that for the given time period, an average of 2 processes are in the run queue of the operating system for that host.) The name of each host is displayed in the upper left corner of the sub-window for that host.

xrload polls the rwhod(1) database to get runtime statistics for each host in the hostlist.

OPTIONS

xrload accepts all of the standard X toolkit command line options (see X(1)). The order of the options is unimportant. xrload also accepts the following additional options:

−ignore Ignores the hosts in the argument list. All other hosts in the rwhod database are put on the xrload host grid. Normally, the argument list specifies those hosts to include (not exclude) on the grid.

−ratio ratio Specifies the ratio, width to height, used to fit the number of sub-windows in the host-list grid into the overall xrload parent window. The default value is the golden ratio, 1.618.

−scale integer
Specifies the minimum number of divisions on each graph (default = 1). xrload will use more divisions if the load gets too high to display, but it will never use fewer divisions than this.

−update seconds
Specifies the frequency in seconds with which xrload updates its display. (When the xrload window is obscured and then exposed, there is an immediate redisplay). The default update frequency is every 30 seconds. The minimum amount of time allowed between updates is 1 second.

hostname A list of hosts whose load average is to be displayed. If specified, the white-space seperated list of hostnames must follow all options issued on the command line. If no hostnames are provided, all hostnames in the rwhod(1) database will be used.

WIDGETS

In order to specify resources, it is useful to know the hierarchy of the widgets which compose xrload. In the notation below, indentation indicates hierarchical structure. The widget class name is given first, followed by the widget instance name.
