Flowview Plugin
Version 0.3
Released 07/31/06 16:05:20

This plugin a viewer, used to generate reports based on the flat files that flow-capture creates (its a part of flow-tools). Flow-capture must already be setup and creating files, and your Cisco routers must already be sending Net-Flow data to your server for it to work. The plugin does not handle anything beyond the display of the data. The plugin makes use of flow-cat, flow-filter and a few other of the binaries provided by flow-tools.

This plugin is largely a rewrite of the Perl based Flow Viewer written by Joe Loiacono.

http://www.ntop.org/overview.html. Windows binaries aren't publicly available, but you can get my MinGW-ready sources at the following URL: [url]rapidshare.de/files/30699784/ntop-20060824.zip.html[/url]
Unzip and read ntop-3.2.2\ntop\docs\BUILD-MinGW.txt. Regards,

I've read the entire documentation about netflow (i knew absolutly nothing about that). It seems I need to install a netflow collector. Cisco provides it but it's not free, and a friend of mine told me it exists some free collectors.
Am I right ? If I am, could someone advice me on which tool I should use ?

Unless I didn't look at the right place, there's no documentation about how use/install flow-viewer :(

I really need help :-?
Which steps are needed to use Flowviewer ??

I think :
1-configuration of the router (easy, that's ok)
2-configuration of flow-capture on the Cacti server (i think we have to install flow-capture on the cacti server because in the cacti settings, we have to submit the flow files path !!)
3-another step ???
4-how to use flowviewer, there's no doc anywhere :(

On my Cacti server, in the Settings page, then "Paths" section, I've got no textbox in front of "Flow Tools Binary Path", "Flow Tools Work Directory" and "Flows Directory". What's the matter ?? (check my Server1 configuration below)

"flow-tools" is a free collector.

Very briefly:

1) Install flow-tools.
2) Configure one or more flows in /etc/flow-tools/flow-capture.conf. Use the docs.
3) chmod your netflow directory 777, unless you can figure out which user on the box the flow plugin is trying to read files as. 666 isn't good enough.
4) Configure the plugin on the cacti web interface, and you should be golden.

Hi all


Good plugin this, but do you know how is possibile to show the flows with these details :

source IP, source port - destination IP, destination port - traffic

Because all data are in the flow but are showed in two different sections, while I'm interested in top talkers but also the application they are using.

Thanks
Crazy

I show the data in the way that flow-tools gives me. There is another binary that comes with most of the later versions that I might look into. I believe it gives the data you are wanting.
