ISAG(1) System Activity Grapher ISAG(1)NAME
isag - Interactive System Activity Grapher
SYNOPSIS
isag [-p datafiles_path] [-c config_file] [-ght gr_height] [-gwd gr_width]
DESCRIPTION
The isag command graphically displays the system activity data stored in a binary data file by a previous sar run. The isag command invokes
sar to extract the data to be plotted.
The data are processed using sar command and slightly transformed to tabular format, and then this format is visualized using gnuplot pro-
gram.
OPTIONS -p datafiles_path
Specify the pathname where are located the daily data files. Default path is: /var/log/sysstat
-c config_file
Specify the configuration file used by the isag command. The contents of this file may depend on isag version number. Default config
file is: $HOME/.isag.cfg.
-ght gr_height
Specify the height of the chart area. Default value is: 400.
-gwd gr_width
Specify the width of the chart area. Default value is: 720.
CONFIG FILE
As mentioned above there is a config file. There are stored following values:
last showed graph
y limits for each kind of graph
It seems useful, because new run doesn't need new settings to obtain same scale.
PREREQUSITIES
Here is list of prerequsities including versioning and built-in features.
Tcl/Tk Version 8.0 or newer.
gnuplot
Gnuplot must have a tkcanvas display.

sag - system activity graph
SYNOPSIS
sag [-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 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(1) for known terminals. Default for term is $TERM.
-x spec x axis specification with spec in the form:
name[op name]...[lo hi]
name is either a string that will match a column header in the sar report, with an optional device name in square brackets, for
example, r+w/s[dsk-1], or an integer value. op is + - * or / surrounded by blank spaces. Up to five names may be specified.
Parentheses are not recognized. Contrary to custom, + and - have precedence over * and /. Evaluation is left to right. Thus,
A/A+B*100 is evaluated as (A/(A+B))*100, and A+B/C+D is (A+B)/(C+D). lo and hi are optional numeric scale limits. If unspecified,
they are deduced from the data.
Enclose spec in double-quotes ("") if it includes white space.
A single spec is permitted for the x axis. If unspecified, time is used.
-y spec y axis specification with spec in the same form as for -x. Up to 5 spec arguments separated by a semi-colon (;) may be given for
-y. The -y default is:
-y"%usr0100;%usr+%sys0100;%usr+%sys+%wio0100"
EXAMPLES
Example 1: Examples of the sag command.
To see today's CPU utilization:
example$ 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]"
