Bandwidth monitoring

The best way is to use pcap library and write small programm (look at http://www.tcpdump.org/pcap.htm) that monitors all packets which have HTTP header with url of the target site (you can skip parsing all protocols, just look into packet's header for url of the site). But this will not work for SSL 
Also try tc (traffic control from iproute2 package). I dont know whether this is appropriate for you but with tc you can create different filters (e.g. according to IP adresses, TCP ports, etc.) and get statistics for that filters, i.e. something similar to
$ tc -s qdisc
qdisc htb 1: dev eth0 r2q 10 default 1 direct_packets_stat 0
Sent 21655 bytes 62 pkt (dropped 0, overlimits 0 requeues 0)
rate 0bit 0pps backlog 0b 0p requeues 0
A realize that all approaches above are very 'low-level', then just search on sf.net

Hello,
I was wondering how one would go about regulating bandwidth of a server running RH Linux 8.0 and Apache. I am running a webserver, and want only one person to be able to download one file at a time. So, they can't click about 10 files and soak up lots of bandwidth. Plus, I would like to cap... (2 Replies)

Nagios - network/systems status monitoring daemon SYNOPSIS
nagios [-h] [-v] [-s] [-d] <main_config_file> DESCRIPTION
nagios is a daemon program that monitors the status of various network accessible systems, devices, and more. For more information, please consult the online documentation available at http://www.nagios.org, or on your nagios server's web page. OPTIONS
main_config_file The main configuration file. On openSUSE systems this defaults to /etc/nagios/nagios.cfg -h A helpful usage message -v Reads all data in the configuration files and performs a basic verification/sanity check. Always make sure you verify your config data before (re)starting Nagios. You can also use the Nagios init script to verify your configuration - try: rcnagios check_verbose -s Shows projected/recommended check scheduling information based on the current data in the configuration files. -d Starts Nagios in daemon mode (instead of as a foreground process). FILES
/etc/nagios Default configuration directory for nagios AUTHOR
