     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.
