graph empty

[taytay06]

Hi all!

I want display the packet size distribution (like ntop plugin) AND the average of this packet size distribution in cacti.
I developed 2 perl script, this is the output:

Code: Select all

monito:/usr/local/cacti/scripts# ./snmp_netflow.pl 172.16.255.105
32:0.1 64:28.3 96:42.1 128:2.3 160:0.8 192:0.6 224:13.7 256:1.2 288:0.2 320:0.2 352:0.2 384:0.3 416:0.3 448:0.7 480:0.3 512:0.3 544:0.2 576:0.2 1024:1.4 1536:5.7 2048:0.0 2560:0.0 3072:0.0 3584:0.0 4096:0.0 4608:0.0 

and

Code: Select all

monito:/usr/local/cacti/scripts# ./snmp_average_netflow.pl 172.16.255.105
214.2

After this, I think of I do every thing... (graph template, data source...)
Graphs was created, but they still empty!

The debug in Graph Management:
RRDTool Command:

Code: Select all

/usr/local/rrdtool/bin/rrdtool graph - \
--imgformat=PNG \
--start=-86400 \
--end=-180 \
--title="CPE-Central - snmp netflow average" \
--base=1000 \
--height=120 \
--width=500 \
--alt-autoscale-max \
--lower-limit=0 \
--vertical-label="taillepack" \
DEF:a="/usr/local/cacti/rra/cpecentral_ipaddcpecent_764.rrd":IPADDCPECENT:AVERAGE \
LINE2:a#FF0000:"Moyenne taille paquet"

RRDTool Says:

OK

And I see this in the cacti debug:

Code: Select all

05/21/2008 04:01:58 PM - WEBLOG: Poller[0] CACTI2RRD: /usr/local/rrdtool/bin/rrdtool graph - --imgformat=PNG --start=-86400 --end=-180 --title="CPE-Central - snmp netflow average" --base=1000 --height=120 --width=500 --alt-autoscale-max --lower-limit=0 --vertical-label="taillepack" DEF:a="/usr/local/cacti/rra/cpecentral_ipaddcpecent_764.rrd":IPADDCPECENT:AVERAGE LINE2:a#FF0000:"Moyenne taille paquet"

Someone can help a little?

Thanks in advance![/code]

If someone want my scripts:

Code: Select all

#!/usr/bin/perl

if (!$ARGV[0]){
print "error: Bad argument\n";
print "usage: ./snmp_netflow.pl [IP Address]\n";
exit 1;
}
open(PROCESS, "snmpget -m all -c public -v2c $ARGV[0] cnfPSPacketSizeDistribution.0|");
@snmpget = <PROCESS>;
close(PROCESS);

chomp(@snmpget); # enleve les '\n' a la fin des lignes
my $string = join(" ",@snmpget);
if ($string =~ m/Hex-STRING:(.*)/) {
        my $hex = $1;
        #print "$hex\n";
        my $i = 0;
        # Tant que l'on trouve deux nombres (separés par des blancs)
        while ($hex =~ m/(\w{2})\s+(\w{2})/g) {
                if ($i >= 1024) {
                        $i = $i + 512;
                }
                else {
                        $i += 32;
                        if ($i == 576+32){
                                $i = 1024;
                        }
                }
                print "$i:" . sprintf("%.1f",hex("$1$2") / 10) . " ";
                }
}

and for average:

Code: Select all

#!/usr/bin/perl

if (!$ARGV[0]){
print "error: Bad argument\n";
print "usage: ./snmp_average_netflow.pl [IP Address]\n";
exit 1;
}

open(PROCESS, "snmpget -m all -c public -v2c $ARGV[0] cnfPSPacketSizeDistribution.0|");
@snmpget = <PROCESS>;
close(PROCESS);

chomp(@snmpget); # enleve les '\n' a la fin des lignes
my $string = join(" ",@snmpget);
if ($string =~ m/Hex-STRING:(.*)/) {
        my $hex = $1;
        my $moy = 0;
        my $i = 0;
        my $div = 0;
        my $hextot= 0;
        # Tant que l'on trouve deux nombres (separés par des blancs)
        while ($hex =~ m/(\w{2})\s+(\w{2})/g) {
                if ($i < 576){
                        $i += 32;
                }
                if ($i >= 1024){
                        $i = $i + 512;
                }
                if ($i == 577){
                        $i = 1024;
                }

                $moy = $moy + $i*(hex("$1$2") / 10);

                $hexa = hex("$1$2") / 10;

                $hextot=$hextot + $hexa;

                if ($i == 576){
                        $i += 1;
                }
        }
        $final=$moy/$hextot;
        print sprintf("%.1f",$final);
}

I hope of I didn't make a mistake for the average calcul!

In the data source debug if found:

It's ok???? I don't understand this debug...
I want juste display the value évolution (min 0, max 4608)...

[taytay06]

So, nobody can help me??

Maybe I'm not clear?
or I didn't post in the right place?

Thanks!

And I think of my problem is here:

This can help you?

I see value = NaN, this want say of my script is wrong??

[taytay06]

I try to change my scrip for decimal number and not float.
But it's the same problem my rrd is full of NaN

Code: Select all

nsp-nms:/usr/local/cacti/scripts#./snmp_netflow.pl 172.16.255.105
32:0 64:27nsp-nms:/usr/local/cacti/scripts#

[Tarsinion]

sorry, i do not have a solution but the same problem. just got "nan" in my graphs ...

Just found this, it might be a help:
http://docs.cacti.net/node/283


Edit: The solution for me was the wrong path to the script. i've installed the php file to /var/www/site/cacti/scripts/ but he was always looking for
/usr/share/cacti/site/scripts/


Thanks for the FAQ to the developer . Sometimes reading helps hehe

[taytay06]

Thank for this link,
I read it...
But I have already the same issue...


And the path for my script is the good path.
Thanks

Maybe my outpout is bad??

What do you think about (without /n at the end):
32:0 64:27

this want said 0% of 32 bytes packet and 27% of 64 bytes packet?
