[Ganglia-developers] how to graph multiple data point in one graph when sending data to gmetric

[Craig S. <kg...@gm...>]

Trying to figure out how to graph multiple data point in one graph when
sending data to gmetric?

Below is what I am doing.... and this work but I have endless graphs. How
can I consolidate this into one with multiple data points? Can I do this?

#!/usr/bin/perl


my $Mapping="/root/Ganglia_Distro/mapping.txt";

$Mapping Looks like this: START
asm01      dm-6
asm02      dm-7
asm03      dm-8
asm04      dm-9
END

open( FILE, "< $Mapping" ) or die "Can't open $Mapping : $!";
    while (<FILE>) {
        my ($alias, $dm) = split(' ');

        my $io_out=`/usr/bin/iostat -x -k -d $dm | grep $dm`;
        my
($dev,$rrqm,$wrqm,$rs,$ws,$rkB,$wkB,$avgrq,$avgqu,$await,$svctm,$util)=split('
',$io_out);

        system("/usr/bin/gmetric -t int16 -n $alias.await -v$await");
        system("/usr/bin/gmetric -t int16 -n $alias.svctm -v$svctm");
        system("/usr/bin/gmetric -t int16 -n $alias.rkB -v$rkB");
        system("/usr/bin/gmetric -t int16 -n $alias.wkB -v$wkB");

    }


This is to get iostat info for my multipathed devices.

THANKS!!!!!

Craig
