[hobbit] How to graph RRD data from DEVMON

[Trent Melcher]

Here is the extra-rrd.pl script, give Thanks to KaYa
(xbgmsharp at gmail.com) for sending this to me originally.  I put just the
if_load test in the script however you can add more for other graphs,  I
have about 15 other stats that I graph this way now. Mostly for our
oracle databases.

#!/usr/bin/perl

# Input parameters: Hostname, testname (column), and messagefile
#$HOSTNAME=$ARGV[0]; ;
$TESTNAME=$ARGV[1]; ;
$FNAME=$ARGV[2]; ;
$filename="/tmp/if_log";

# Read the entire files
open (FILEHANDLE,$FNAME) || die ("cant read file\n");
@input = <FILEHANDLE>;
close (FILEHANDLE);

if ( $TESTNAME eq "if_load") {

           # Analyze the message we got
           open(OUT, ">", $filename);
           foreach $line (@input) {
                   if ($line =~ /(^[A-Z].*) (\d+):(\d+)$/ ) {
                           # The RRD dataset definitions
                           print "DS:in:DERIVE:600:0:U\n";
                           print "DS:out:DERIVE:600:0:U\n";

                           # The filename
                           print "if_load_$1.rrd\n";

                           # The data
                           print "$2:$3\n";
                   }
           }
        close (OUT);
}
