NAME
      sag - system activity graph

SYNOPSIS
      sag [options]

DESCRIPTION
      sag graphically displays the system activity data stored in a binary data
      file by a previous sar(1M) run.  Any of the sar data items may be plotted
      singly, or in combination; as cross plots, or versus time.  Simple
      arithmetic combinations of data may be specified.  sag invokes sar and
      finds the desired data by string-matching the data column header (run sar
      to see what is available).  These options are passed through to sar:

      -s time  Select data later than time in the form hh[:mm].  The default is
               08:00.

      -e time  Select data up to time.  The default is 18:00.

      -i sec   Select data at intervals as close as possible to sec seconds.

      -f file  Use file as the data source for sar.  The default value is the
               current daily data file (/usr/adm/sa/sadd).

      Other options:

      -T term  Produce output suitable for terminal term.  The default value is
               $TERM.  The following known terminals are available:

                  300   DASI 300.
                  300S  DASI 300s.
                  450   DASI 450.
                  4014  Tektronix 4014.

      -x spec  x axis specification with spec in the form:
               "name[op name] . . . [lo hi]"

      -y spec  y axis specification with spec in the same form as above.

      Name is either a string that will match a column header in the sar
      report, with an optional device name in square brackets, (such as
      r+w/s[dsk-1], or an integer value.  Op is one of four characters (``+'',
      ``-'', ``*'', or ``/''), surrounded by blanks.  (Parentheses are not
      recognized.)  Up to five names may be specified.  Contrary to custom,  +
      and  -  have precedence over  *  and  /".  Evaluation is done from left
      to right.  Thus A / A + B * 100 is evaluated (A/(A+B))*100, and
      A + B / C + D is (A+B)/(C+D).  Lo and hi are optional numeric scale
      limits.  If unspecified, they are deduced from the data.

      A single spec is permitted for the x axis; if unspecified, time is used.
      For the y axis, specify up to five specs, separated by semi-colons (;).
      If you specify more than one argument to -x or -y, and leave one or more

      blank spaces between list items, enclose the list in double quotes ("").
      The default value for the -y option is

      -y "%usr 0 100; %usr + %sys 0 100; %usr + %sys + %wio 0 100"

EXAMPLES
      For a report on today's CPU utilization:

            sag

      For a report on the activity of all disk drives over a 15-minute period:

            TS=date +%H:%M
            sar -o tempfile 60 15
            TE=date +%H:%M
            sag -f tempfile -s $TS -e $TE -y "r+w/s[dsk]"

FILES
      /usr/adm/sa/sadd      daily data file for day dd
