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:
- -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.
Other
options:
- -T term
- Produce output suitable for terminal term. Default for
term is $TERM
.
- -x spec
- x axis specification with spec in the form:
name[op
name]...[lo hi]
- name
- is either a string that will match a column header in
the sar report, with an optional device name in square brackets, for example,
r+w/s[dsk-1], or an integer value. op is + - * or / surrounded by blank
spaces. Up to five names may be specified. Parentheses are not recognized.
Contrary to custom, + and - have precedence over * and /. Evaluation
is left to right. Thus, A / A + B * 100 is evaluated as (A/(A+B))*100, and
A + B / C + D is (A+B)/(C+D). lo and hi are optional numeric scale limits.
If unspecified, they are deduced from the data.
- Enclose
- spec in double-quotes
("") if it includes white space.
- A single
- spec is permitted for the x axis.
If unspecified, time is used.
- -y spec
- y axis specification with spec in the
same form as for -x. Up to 5 spec’s separated by a semi-colon (;) may be given
for -y. The -y default is:
-y "%usr 0 100; %usr + %sys 0 100; %usr + %sys +
%wio 0 100"
To see today’s CPU
utilization:
example$ 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]"
- /usr/adm/sa/sadd
- daily data file for day dd
