VISMON(9.1) VISMON(9.1) NAME vismon, sysmon, vwhois - system statistics and mail notification SYNOPSIS vismon [ -n ] [ -m ] [ system ... ] sysmon [ -n ] [ -m ] [ system ... ] vwhois person DESCRIPTION Vismon monitors use of one or more Unix systems. It displays time of day, announcements, and CPU usage statistics. CPU usage is reported as a numerical load average (average number of runnable processes) and its change in the last minute, and a bar graph showing, left-to-right, the propor- tion of CPU time spent in: default-priority user processes, low priority (nice) processes, system kernel, stream I/O, and idle time. Arrival of mail or communications via wall(8) or write(1) is announced. Mail announcements include an icon of the sender. Communications appear in a shell (sh(1)) layer superimposed on vismon's layer. This layer may be used for reply. The options are: -n Update the bar graph every n seconds. (n=5 by default.) -m Do not monitor CPU usage on other systems. Button 2 selectively toggles the monitoring of other sys- tems. The list of systems is obtained from one of the fol- lowing: a file named in the VISMON enviroment variable, or Sysmon is the same as vismon without icons. Vwhois causes a dummy mail announcement from person to appear in vismon layers.
