[ManishRoy]

Hi,

I am new bee  in RRD. i am trying to create a graph. 
my code is:

Create RRD File

#!usr\bin\perl

use RRDs;

#
# Create Database
#

$db = "/tmp/RRDDemo/RRDData.rrd";

print "--------------- DB Created Start \n ";

RRDs::create
(
	$db,
	"--step=300",
	"DS:in:COUNTER:320:U:U",
	"DS:out:COUNTER:320:0:U:U",
	"RRA:AVERAGE:0.5:1:288",
	"RRA:AVERAGE:0.5:12:168",
	"RRA:MIN:0.5:12:168",
	"RRA:MAX:0.5:12:168",
);

print RRDs::error();

print "\n--------------- DB Ends Start ";


Update RRD


#!usr\bin\perl

use RRDs;

#
# Update Database
#

$db = "/tmp/RRDDemo/RRDData.rrd";

print "--------- DB UpdationStarts-------\n";

$currtime=time();
$time=time()+100;
$value=100;
$value1= $value + 10;
RRDs::update($db,"$time:$currtime:$value1");
#RRDs::update($db,"$time:$value1");

print RRDs::error(),"\n";

print "--------- DB UpdationStarts-------";


Create Graph

#!usr\bin\perl
use RRDs;

#
# Graph Creation
#

$time =  1213621589-100;
$time1=  time();
RRDs::graph
(
	"/tmp/RRDDemo/INOUTGraph.png",
	"--title=In-Out Data",
	"--vertical-label=Value",   
	"--lower-limit=0",          
	"DEF:a=/tmp/RRDDemo/RRDData.rrd:in:AVERAGE",  
    "DEF:b=/tmp/RRDDemo/RRDData.rrd:in:MAX",
	"AREA:a#00ff00:Incoming",
	"LINE1:b#ff0000:Max Incoming",
);
	
print RRDs::error();
