PNETPROBE is a series of Perl scripts to catch and manage tcpdump data. It uses MySQL to dump data, and uses GD::Graph for all plotting functions. This tool will be ideal to see what is flowing in how many quantities on your network.

I am pleased to announce the first alpha code for pnetprobe. Included in this package is two Perl scripts to populate and query the MySQL database. ONLY for the brave! Cheers ;)
First release - VERY alpha
Many may wonder: "Why another network monitoring app?". Well, I just couldn't find something I liked, so I decided to write my own little solution. Not that the other products are not cool. NTop is really cool, but as with most similar apps, it lacks database support. Also, I don't really need that fine granuality. I want to plug into a network and within 1 hour get a good idea what's going on. At this stage I don't interface with low level libs. I simply parse the output from tcpdump and write the summaries to a MySQL database. There is a specific reason for this. If you have this "probe" on a laptop, you can analyse previously dumped data from tcpdump, if that was written to a file. The reasoning here is that you might not want a "sniffer" and DB running on your production servers, but you may want to examin some network info from time to time. Eventually you will also be able to get realtime live info. I plan to do this with a Qt interface on Kylix. This can interface directly with the MySQL DB and update every x seconds. There is also the possibility to port the fron-end to Windows. The web interface will be first, though, and will be used as the primary front end to the DB, in order to generate some of the "planned" standard reports, as well as some custom reports. All reports will be in HTML/PS format. Well, you should see some code come in soon. Cheers Nico
