We had a customer approach us the other day with an nprobe issue. Apparently, he could see the NetFlow v9 data in Flow View of Scrutinizer, but he couldn’t report on the data. How come?

He sent us a Wireshark packet capture and brought up Flow View. Flow View is a way to see the raw flows (inclusive of all columns) being exported by a device.

Anyway, in Flow View everything looked normal, but then one of our developers spotted the word ‘post’ in front of a couple of import column names. We (and Scrutinizer) expect to see ‘octetDeltaCount’ and instead, the customer had configured nProbe to kick out ‘postOctetDeltaCount’.

What’s your favorite color? Chances are that your favorite color is not the same as mine. When you use Windows, are you a fan of the old classic view, or do you go for the new Windows look?

We have all been talking about Plixer’s NetFlow analyzer, and how it provides the best in traffic analysis, with its ability to support Flexible NetFlow, NBAR, and Cisco ASA NSEL. But did you know that as a Scrutinizer user, you have different options when it comes to how you want our NetFlow and sFlow Traffic Analysis Tool to look?

Currently there are 5 different skin types available to select from. They are configurable on a per user basis. So if you are in a dark kind of mood, you can change to a dark skin with either green or yellow text.

Thanks to Jimmy D, our renowned International Sales Channel Manager, we have a proven solution for monitoring NetFlow traffic for home users.

A situation arose for Jim where his wife and daughter would be in Florida caring for his parents while he was still here in Maine. The geek that he is, he didn’t want distance to keep them apart.

So he decided to provide voice, video, and network monitoring while they were in Florida. To achieve this, he decided to set up a small embedded server rack in his parents’ Florida home. This would allow for VoIP, Video, network traffic monitoring, and a web server.

Just about all NetFlow Analyzers get the interfaces names of the routers and switches using SNMP. Another reason why SNMP vs. NetFlow is really a no contest. Anyway, we can get the names of interfaces using NetFlow via something called NetFlow option templates.
