rrdtool

Witam,
Mam problem z wykresami generowanymi przy pomocy rrdtool'a. Pod tym adresem jest przykładowy wykres --> http://marduk.rootnode.pl/p2p_d.png .Nie wiem skąd biorą się takie skoki na tych grafikach. Wykresy generuję w następujący sposób:

tworzenie bazy danych:

Kod:

rrdtool create -s 300 /etc/rrd/databases/p2p_d.rrd DS:marduk:COUNTER:600:0:U DS:lukasz:COUNTER:600:0:U DS:serek:COUNTER:600:0:U DS:sandman:COUNTER:600:0:U DS:maciek:COUNTER:600:0:U DS:yojin:COUNTER:600:0:U DS:leon:COUNTER:600:0:U DS:chaos:COUNTER:600:0:U DS:chaos_l:COUNTER:600:0:U DS:eman:COUNTER:600:0:U DS:w00x:COUNTER:600:0:U DS:w00x_l:COUNTER:600:0:U RRA:AVERAGE:0.5:1:1200 RRA:AVERAGE:0.5:12:2400

pobieranie danych do bazy:


#!/bin/bash

marduk=`iptables -t mangle -L MARK_P2P_D -x -v | grep marduk | awk '{print $2;}'`
lukasz=`iptables -t mangle -L MARK_P2P_D -x -v | grep lukasz | awk '{print $2;}'`

Re: rrdtool

rozwiązałem ten problem w następujący sposób (może komuś się przyda):
zmieniłem typ z COUNTER na ABSOLUTE a w skryptach zliczających dane z iptables dodałem wpis zerujący liczniki iptables po każdym wywołaniu skryptu:

iptables -t mangle -L MARK_P2P_D -Z > /dev/null

i działa ;]
