Unix&Linux

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

选件

-e time	最多选择数据的时间。默认值为18:00。
-f file	将文件用作sar的数据源。默认为当前的每日数据文件/ usr / adm / sa / sadd。
-i sec	选择间隔尽可能接近秒秒的数据。
-s time	请以hh [ ：mm ]的形式选择晚于时间的数据。默认值为08:00。
-T term	产生适合期末输出的输出。有关已知端子，请参见tplot。term的默认值为环境变量 $ TERM的值。
-x spec	x轴规格，规格形式为： name[ op name ] ... [ lo hi ] name是将与sar报告中的列标题匹配的字符串，并在方括号中带有可选的设备名称，例如r + w / s [dsk-1]或整数值。该运算是+，- ，，或/，由空格包围。最多可以指定五个名称。不识别括号。与自定义相反，+和-优先于和/。评估从左到右。因此，*将A / A + B 100评估为（A /（A + B））* 100，而A + B / C + D为（A + B）/（C + D）*。lo和hi是可选的数字刻度限制。如果未指定，则从数据中推导出。如果spec*包含空格，则将其括在双引号（“”）中。x轴允许使用单一规格。如果未指定，则使用时间。
-y spec	y轴规格，其规格与-x相同。最多可以为-y给出5个用分号（;）分隔的规范参数。该-y默认为： -y“％usr0100;％usr +％sys0100;％usr +％sys +％wio0100”

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

Options

-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. The 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+B100 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"

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]"

依次执行以上四个命令后，将显示所有磁盘驱动器在15分钟内的所有活动。

sag -f /tmp/tempfile -s $TS -e $TE -y "r+w/s[dsk]"

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