OK I will rephrase my question. I combined the two together. Sorry about that. First off I would like to know what the list would recommend for network flow. Showing bottlenecks, src and dst of packets. I have used ntop, and was curious what else was out there.
That's what I suspected is you either weren't clear or had two different things. I mostly use flow tools directly, with a handful of custom scripts, reports, etc gluing it together. There are some really slick commercial offerings out there but I haven't really used any of them extensively. flow tools requires your router produce c/j/sflow records and export them to the flow collector for later analysis.
The other question was geared toward system monitoring. Nagios looks promising. I was wondering what others were using, and what would be recommended.
I use nagios pretty much exclusively. Most of the checks require no custom software on the clients which for us is a huge boon. Further it can be setup in a distributed manner (which for checking 1200+ elements you'll quite possibly need to do depending on what sorts of checks you're doing).
HTH!
