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(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 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(1G)
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 they include whitespace. The -y
default is:

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]"
