[c-nsp] Netflow analysis tools?

[Rick Coloccia, Jr.]

+1 Plixer/Scrutinizer.  Very affordable, powerful, easy to use, very 
responsive to service requests.  Been happy for years with them.

The SW pricing model is such that the NTA license must follow the NPM license, so if you have an SLX (unlimited) license (like we have), you need an SLX NTA license ($15K list).  The alternative is that you can purchase another small 25-node license of Orion *and* NTA.  Scrutinizer 25-node license was less expensive (with appropriate end-of-quarter discounts) and supports unlimited number of interfaces per exporter.  Yearly software maintenance is less expensive, too.

Solarwinds has no plans on supporting IPv6 or MPLS - IPv6 has been a feature request for more at least 3 years on their support forum and unless one of their Fortune 500 enterprise customers absolutely demands MPLS support, forget about that getting added.

He gave me the end-of-quarter parameters and checked in with me once every week or two weeks or whenever I had a question.  The Solarwinds sales person kept calling and emailing, and just plain being a damned pest about it.  He pissed me off, and to be honest, this was one of the biggest reasons I went with Plixer.  Note to sales people - I don't give a s**t how tenacious you are - when I tell you not to bug me and flat out tell you that you are being a pest, you can be sure I won't purchase your product.

Solarwinds has a more "polished" interface and is definitely a lot more "pretty" to look at, but when it came right down to it, we felt that Scrutinizer was the better choice, given the above points.  That said, SW NTA is a great product and might be a good choice if you have executives or non-technical people that like great-looking reports and/or if you are lonely and feel like talking to a sales droid whose only motivation is to sell you NTA with the ingrained tenacity of a T-1000 looking for John Connor.
