nprobe and PF_RING are by far the most comprehensive tools I've seen to do this under Linux: http://www.ntop.org/nProbe.html We've been trying to work something out with Luca (from ntop/PF_RING/nprobe) to further the SIP/RTP abilities of PF_RING/nprobe. We haven't worked anything out yet but I would be interested to hear how the Asterisk community feels about this. The plugin architecture could also allow for an IAX flow analyzer, for instance... I'm also a bit disappointed by the existing flow collectors out there but that's a whole other rant. I can attest the basic claims of performance, speed, and efficiency are all true based on my experiences with nprobe in AstLinux. I don't think I ever fully integrated PF_RING with AstLinux but I understand it increases the performance and capabilities of nprobe dramatically. One of the best features of nprobe is the ability to not only export UDP flows directly to a flow collector but to also write out that data to ASCII and/or binary logs that can later be parsed. If you could combine some timestamps with this flow data you could easily provide for quality monitoring with history for every SIP/RTP (IAX w/ plugin) flow. You could also analyze other flows (HTTP, evil BitTorrent, etc) over the same connection to correlate potential voice quality issues with other types of traffic on the network/circuit. This ability alone is why I think this solution is so powerful. Of course some of these capabilities could be built directly into Asterisk but Asterisk wouldn't give you data on other flows, would it? Also keep in mind a single instance of nprobe/PF_RING running on a Linux router in a large VoIP/Asterisk network could provide flow data and statistics for the entire network (what people do with NetFlow now). Something to think about... Of course another issue is the license and source availability. You have to pay for the source but it's GPL licensed. Let your mind ponder that for a minute... There are some interesting docs, whitepapers, etc on the site (nProbe/PF_RING) if you are interested. -- Kristian Kielhofner http://blog.krisk.org http://www.submityoursip.com http://www.astlinux.org http://www.star2star.com _______________________________________________ -- Bandwidth and Colocation Provided by http://www.api-digital.com -- asterisk-users mailing list To UNSUBSCRIBE or update options visit: http://lists.digium.com/mailman/listinfo/asterisk-users
