sag(1) User Commands sag(1)NAMEsag - system activity graph
SYNOPSISsag [-e time] [-f file] [-i sec] [-s time] [-T term]
[-x spec] [-y spec]
DESCRIPTION
The sag utility 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). The sag utility requires a
graphic terminal to draw the graph, and uses tplot(1) to produce its
output. When running Solaris 2.x and OpenWindows, perform the following
steps:
1. Run an xterm as a Tektronics terminal: prompt# xterm -t
2. In the xterm window, run sag specifying a tek terminal:
prompt# sag-T tek options
OPTIONS
The following options are supported and passed through to sar (see
sar(1)):
-e time Select data up to time. 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 sec‐
onds.
-s time Select data later than time in the form hh[:mm]. Default is
08:00.
-T term Produce output suitable for terminal term. See tplot(1) for
known terminals. Default for term is $TERM.
-x spec x axis specification with spec in the form:
name[op name]...[lo hi]
name is either a string that will match a column header in
the sar report, with an optional device name in square
brackets, for example, r+w/s[dsk−1], or an integer value. op
is + − * or / surrounded by blank spaces. Up to five names
may be specified. Parentheses are not recognized. Contrary
to custom, + and - have precedence over * and /. Evaluation
is left to right. Thus, A/A+B*100 is evaluated as
(A/(A+B))*100, and A+B/C+D is (A+B)/(C+D). lo and hi are
optional numeric scale limits. If unspecified, they are
deduced from the data.
Enclose spec in double-quotes ("") if it includes white
space.
A single spec is permitted for the x axis. If unspecified,
time is used.
-y spec y axis specification with spec in the same form as for -x.
Up to 5 spec arguments separated by a semi-colon (;) may be
given for -y. The -y default is:
-y"%usr0100;%usr+%sys0100;%usr+%sys+%wio0100"
EXAMPLES
Example 1 Using the sag Command
To see today's CPU utilization:
example$ sag
To see activity over 15 minutes of all disk drives:
example$ TS=`date +%H:%M`
example$ sar -o /tmp/tempfile 60 15
example$ TE=`date +%H:%M`
example$ sag-f /tmp/tempfile -s $TS -e $TE -y "r+w/s[dsk]"
FILES
/usr/adm/sa/sadd Daily data file for day dd
