SAG(ADM)                             UNIX System V



     Name
          sag - system activity graph


     Syntax
          sag [ options ]


     Description
          The sag command graphically  displays  the  system  activity
          data  stored  in  a  binary data file by a previous sar(ADM)
          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.   The  sag
          command  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].
                   Default is 08:00.

          -e time  Select data up to time.  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.   Default  is
                   the current daily data file /usr/adm/sa/sadd.

          Other options:

          -T term  Produce output suitable  for  terminal  term.   See
                   tplot(ADM)  for  known terminals.  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  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.   Up to 5 spec's separated by ; may be given
          for -y.  Enclose the -x and -y arguments in "" if blanks  or
          \<CR> are included.  The -y default is:

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


     Examples
          To see today's CPU utilization:
               sag

          To see activity over 15 minutes of all disk drives:
          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.
