[mrtg] RRDTOOL error

[Gayan S. Amarasiri]

Hi,

 

I am using the following script to draw a graph using rrdtool. But it is
not displaying any value. When I check with "rrdtool fetch" command it
displayed as "nan". Please help on this.

 

 

use lib qw(/lib/perl/5.8.0/i386-linux-thread-multi/);

use RRDs;

#$dt= print localtime();

$ipadd="192.168.3.1" ;

sub trim($)

{

 my $string = shift;

 $string =~ s/^\s+//;

 $string =~ s/\s+$//;

 return $string;

}

 

sub gettrap{

$getval= join (" ", "snmpget -v2c -c admin" ,$ipadd,$_[0],"|");

open (SNMPGET,"$getval");

$val=<SNMPGET>;

chop($val);

return split (/:/ , $val);

}

 

sub castStrInt {

            my $t;

      foreach my $d (split(//, shift())) {

      $t = $t * 10 + $d;

      }

      return $t;

}

 

@in =gettrap("1.3.6.1.2.1.2.2.1.10.14");

@out= gettrap("1.3.6.1.2.1.2.2.1.16.14");

$kin=trim($in[3]);

$kout=trim($out[3]);

$intin=castStrInt($kin);

$intout=castStrInt($kout);

#system("rrdtool update /var/www/html/testrrd/myrouter.rrd
N:$intin:$intout");

#system("rrdtool update /var/www/html/testrrd/myrouter1.rrd
N:$intin:$intout");

RRDs::update ("myrouter.rrd", "N:$intin:$intout");

RRDs::graph ("myrouter-day.png","--start=-86400",
"DEF:inoctets=myrouter.rrd:input:AVERAGE",
"DEF:outoctets=myrouter.rrd:output:AVERAGE", "AREA:inoctets#FF00ff:In
traffic", "LINE1:outoctets#FF00FF:Out traffic");

 

Thanks & BR,
