Sorry for the html email - I was trying to show my config and page view.. Im playing around with ntop and sflow for the first time and could do with some help... I am willing to propose a deal for those that are interested? I have to document the setup and config for our internal systems, so will be willing to share this documentation to be published to a wiki if anyone fancies it? Im quite new to Linux and network monitoring in general, but can share my experience from a newbies point of view and hopefully save someone else the pain.
We are a HP network and our core and distribution layer switches support sfow in hardware :-) I have installed ntop onto an Ubuntu server and have configured one switch on a trial basis to send sflow data to the ntop server at a sampling rate of 1 in every 250 packets. Eventually I am hoping to have about 50 switches monitored by sflow.. I have used apt-get to install ntop and then through the web interface I have configured an sflow device and set the interface address to the IP of the switch. White and black lists have been left blank. I can see that there is data being received as I have unicasts, multicasts, and broadcast figures in the sflow interface statistics as well as a packet count in the flow statistics chart (49 so far) If I then switch NIC's and look at the Summary - Traffic page it is reporting Total Received (ntop) 1 which doesn't tie up with the figures on the sflow interface config page? All graphs although enabled are not showing any data, though I am guessing that there is additional config to do. If someone can help with the basic sflow config and things to check and what config files to edit, I can knock up a checklist and then get started on the graph config!
