About sag

On Solaris, the sag utility graphically displays the system activity data stored in a binary data file by a previous sar run.

sag syntax

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


-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 seconds.
-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 for known terminals. Default for term is the value of the environment variable $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:

See today's CPU utilization.

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

The above four commands, when executed in sequence, will display all activity over 15 minutes of all disk drives.
