SAR

[Sean McGlynn]

Thank you.  I think I will try to make use of your script, and the tutorial looks good as well.

Sean,

I don't bother saving the sysstat data longer than the default, but I 
create a series of data files of my own, from the sa database.  Here's a 
very brief and unsophisticated Perl script that will create a report 
each day.  I run it from cron just before midnight each day.  You can do 
with it what you will.  Also have a look at the sysstat web page for 
some good ideas.  http://perso.orange.fr/sebastien.godard/tutorial.html

daily-sar.pl
-----------------------------------
#!/usr/bin/perl -w

use strict;
use warnings;

my $today = `date +%F`;
my $outfile = "/root/sar/sar.$today";

my @u = system("/usr/bin/sar -u >> $outfile");
my @d = system("/usr/bin/sar -d >> $outfile");
my @b = system("/usr/bin/sar -b >> $outfile");
my @q = system("/usr/bin/sar -q >> $outfile");
my @r = system("/usr/bin/sar -r >> $outfile");

exit;

Is there some way to modify the process so the files are stored indefinitely?  I know I could write a script to copy the files to an archive directory, but I'm thinking that something is causing the files to be deleted, and it would be cleaner to change that aspect of it.
