Cacti

Cacti is a complete network graphing solution designed to harness the power of RRDTool's data storage and graphing functionality. Cacti provides a fast poller, advanced graph templating, multiple data acquisition methods, and user management features out of the box. All of this is wrapped in an intuitive, easy to use interface that makes sense for LAN-sized installations up to complex networks with hundreds of devices.  http://cacti.net/

iptables

http://forums.cacti.net/about8091.html
download cacti templates. Da iptables als root ausgeführt werden muss, wird das script über sudo aufgerufen: /etc/sudoers

#logging
Defaults syslog = local2
# User privilege specification
www-data    ALL = NOPASSWD: /usr/share/cacti/site/scripts/iptables.pl

Damit der syslog nicht damit unnötig 'beloggt' wird, loggen wir an log-facility local2 und damit in ein eigenes Logfile /etc/syslog.conf:

...
*.*;auth,authpriv.none;mail.!*;daemon.!info;cron.!*;local2.none         -/var/log/syslog
...
local2.* /var/log/sudo.log

#!/usr/bin/perl
###
### This is a quick perl script to
### pull bandwidth usage from iptables chains
###
### If you use/optimize this script, please let me know.
### Brian Stanback : brian [at] stanback [dot] net
##
### Example iptables rule for web bandwidth usage:
### > iptables -N WWW
### > iptables -A WWW -j ACCEPT
### > iptables -A INPUT -p tcp -m tcp --dport 80 -j WWW
### > iptables -A OUTPUT -p tcp -m tcp --sport 80 -j WWW
###
### Run "iptables.pl WWW" as root to test, note that you can
### combine more than one protocol into a single chain.
###
### Sudo Configuration (/etc/sudoers)
### > www-data    ALL = NOPASSWD: /usr/share/cacti/scripts/iptables.pl
###
### The Input String should be set to "sudo <path_cacti>/scripts/iptables.pl <chain>"
### and you will need to setup an input field so that the <chain> argument can be passed.
###
### The data input type should be set to COUNTER
###

## modified by: Paul Campbell <forums@campbell-multimedia.co.uk>
## Now returns a seperate entry for each rule.  Output for a
## 3 rule chain might now be:
## rule1:123 rule2:456 rule3:789

if ($ARGV[0]) {
$chains = `/sbin/iptables --line-number -xnvL $ARGV[0]`;
@chains = split(/\n/, $chains);
