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 proportion 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 ap- pear 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 systems. The list of systems is obtained from one of the following: 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. FILES terminal program remote monitoring program responder for remote monitoring vismon pictures menu of machines SEE ALSO face(9.7), faced(9.5) DIAGNOSTICS `Can't open comm window' means a shell layer cannot be created. To re- ceive any further communications, delete some layer. BUGS There's more to system performance than meets the eye. VISMON(9.1)
