sar -d formatting

I have a very large sar output file and from it I have extracted the sar -d info to a text file as follows:

sar -d -f sa07 > sa07-disk.out

Now what I'm trying to figure out is if there's any way to get dates in front of every entry in my output by reformatting it via a script or set of commands.. I'm ultimately trying to import this data into a spreadsheet to sort and look at highest to lowest colums, but I also need to know the times for each of the entries I'm interested in.

Any ideas that can be shared would be greatly appreciated.

Thanks,

Re: sar -d formatting

You have some sample output from sa07-disk.out?

Re: sar -d formatting

Hello,

Several years ago, I did just that. Albeit,
it was for Solaris servers but the logic
is the same.

Here is the Perl script:

#!/usr/bin/perl

# 00:00:00 device %busy avque r+w/s blks/s avwait avserv

#use strict;
use Getopt::Std;
use File::Basename;

use vars qw(@Header $z %Disk %RW @Keyspaces @Onetime $Time
$FF $SAFile $Disk @WholeComplex $RW %WholeComplex @Servdata
$Realmonth $Month $Sec $Min $Hour $DayOfMonth $Month $Year
$Result $FR $DayOfWeek $DayofYear $IsDST);

($Sec, $Min, $Hour, $DayOfMonth, $Month, $Year, $DayOfWeek, $DayofYear, $IsDST) = localtime ;

# localtime returns January..December as 0..11.
$Realmonth = (Jan, Feb, Mar, Apr, May, Jun, Jul, Aug, Sep, Oct, Nov, Dec)[$Month];
$Month++;
$Year = 1900 + $Year;

($::opt_f) = (); #avoid warning message
getopts('f:');
$::SAFile = $::opt_f;

if (! "$SAFile" ) {
$FF = "";
} else {
$FF = "-f $SAFile";
}

$FR = basename($SAFile);

print "Processing SAR file $SAFile ($FR)\n";

$Result1 = "/mydir/mysrv-sar-data/${FR}${Realmonth}${Year}-DISK_RWS.txt";
$Result2 = "/mydir/mysrv-sar-data/${FR}${Realmonth}${Year}-DISK_BUSY.txt";
$Result3 = "/mydir/mysrv-sar-data/${FR}${Realmonth}${Year}-DISK_AVSERV.txt";

open(To1, ">$Result1") or die "ERROR: Can't open $Result: $!";
open(To2, ">$Result2") or die "ERROR: Can't open $Result: $!";
open(To3, ">$Result3") or die "ERROR: Can't open $Result: $!";

open(FROM,"sar -d $FF | awk '! /%/ && ! /,/ {print}'|") || die "Cannot open sar data";
while () {
chomp;
if (/:/ .. /^$/) {
@Keyspaces = split(/\s+/, $_);
if (grep(/:/, $_)) {
$Time = $Keyspaces[0];
printf To1 "\n$Time ";
printf To2 "\n$Time ";
printf To3 "\n$Time ";
if (! grep(/\bTimeStamp/, @Header)) {
push @Header, "\nTimeStamp ";
}
}

$Disk{$Time} = $Keyspaces[1];
$Busy{$Time} = $Keyspaces[2];
$Avserv{$Time} = $Keyspaces[$#{Keyspaces}];
$RW{$Time} = $Keyspaces[4];
printf To1 "$RW{$Time} ";
printf To2 "$Busy{$Time} ";
printf To3 "$Avserv{$Time} ";
if (! grep(/\b$Disk{$Time}/, @Header)) {
push @Header, "$Disk{$Time} ";
}
}
}

printf To1 "@Header\n";
printf To2 "@Header\n";
printf To3 "@Header\n";
exit(0);

In this specific case, I save different
metrics into different files, but it
is quite easy to put them into the same file :)

I also just tested my old script on Fedora 10
server and it worked. Here are parts of
myhost-sa15Jan2009-DISK_RWS.txt:

Re: sar -d formatting

By the way, here is how raw sar files look like
(so that you can compare them with what
gets reported via my Perl script):
