RE: [hobbit] How to graph RRD data from DEVMON

["Eric Meddaugh" <etmsys (at) rit.edu>]

I made the perl script to handle multiple inputs from other "data"
providers.  It'd flexible enough that should be able to handle most data
sent to it.   There is a certain "format" you'd need to follow to use
it, but it can be modified to fit most everything.  

I wrote it since only one data reader is allowed to be defined and must
be able to handle all the different data types sent to it.

Thank's to all for your help. 

Galen, you are right, Eric has some simaler scripts at the shire. 

I wil try to setup the rrd graphs with this script and inform you on my
progress.

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.

# 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
