nTOP banged dah !

Apaan tuh nTOP kk ?

Nah waktu pertama kali saya juga bertanya yg sama... eh rupanya aplikasi Linux yg kaya di tepe tepe itu eh kayak mrtg yg udah melegenda dan sering dipake. Ya gitu deh...

ntop is a network traffic probe that shows the network usage, similar to what the popular top Unix command does. ntop is based on libpcap and it has been written in a portable way in order to virtually run on every Unix platform and on Win32 as well.

ntop users can use a a web browser (e.g. netscape) to navigate through ntop (that acts as a web server) traffic information and get a dump of the network status. In the latter case, ntop can be seen as a simple RMON-like agent with an embedded web interface. The use of:

• a web interface
• limited configuration and administration via the web interface
• reduced CPU and memory usage (they vary according to network size and traffic)

• Sort network traffic according to many protocols
• Show network traffic sorted according to various criteria
• Display traffic statistics
• Store on disk persistent traffic statistics in RRD format
• Identify the indentity (e.g. email address) of computer users
• Passively (i.e. withou sending probe packets) identify the host OS
• Show IP traffic distribution among the various protocols
• Analyse IP traffic and sort it according to the source/destination
• Display IP Traffic Subnet matrix (who's talking to who?)
• Report IP protocol usage sorted by protocol type
• Act as a NetFlow/sFlow collector for flows generated by routers (e.g. Cisco and Juniper) or switches (e.g. Foundry Networks)
• Produce RMON-like network traffic statistics
