     NAME
          sag - system activity graph

     SYNOPSIS
          sag [-e time] [-f file] [-i sec] [-s time] [-T term]
          [-x spec] [-y spec]

     DESCRIPTION
          sag graphically displays the system activity data stored in
          a binary data file by a previous sar(1) 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's available).  These flag options are passed
          through to sar:

          -e time  Select data up to time in the form hh[:mm], where
                   hh is the time in hours (military time) and mm is
                   the time in minutes.  Default is 18:00.

          -f file  Use file as the data source for sar.  Default is
                   the current daily data file /usr/adm/sa/sadd.

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

          -s time  Select data later than time.  Default is 08:00.

          Other flag options:

          -Tterm   Produce output suitable for terminal term.  See
                   tplot(1G) for known terminals.  If term is vpr,
                   output is processed by vpr -p and queued to a Ver-
                   satec printer.  Default for term is $TERM.

          -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, e.g., r+w/s[dsk-1], or an integer value.  op is +,
          -, *, or / surrounded by blanks.  Up to five names may be
          specified.  Parentheses are not recognized.  Contrary to
          custom, + and - have precedence over * and /.  Evaluation is
          left to right.  Thus

     sag(1G)                                                   sag(1G)



               A / A + B * 100

          is evaluated as

               (A/(A+B))*100

          and

               A + B / C + D

          is

               (A+B)/(C+D)

          lo and hi are optional numeric scale limits.  If unspeci-
          fied, they are deduced from the data.

          A single spec is permitted for the x axis.  If unspecified,
          time is used.  Up to 5 spec's separated by ; may be given
          for -y.  Enclose the -x and -y arguments in "" if blanks or
          \RETURN are included.  The -y default is:

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