SUNY Geneseo Network Manager Rick Coloccia found that analyzing Cisco NetFlow packets was the key to network traffic management and monitoring internet use and abuse.

Using Scrutinizer NetFlow Analyzer, he was able to respond to the RIAA’s (Recording Industry Association of America) allegations of students illegally downloading or sharing of music.

The following article, “Scrutinizer Brings Flow Analytics to SMBs“, written by David Diaz, was recently featured on TechCrunchIT.

David points out that with the low initial cost for Scrutinizer NetFlow & sFlow Analyzer, it is a very affordable Flow Analytics solution for small and medium-sized businesses.

This flow analysis tool can also be deployed centrally and accessed globally via the web interface.  What this means is that one install of Scrutinizer can provide network management information for your entire network and accessible by everyone on the network management team, regardless of geographical location.

The holiday’s are nearly upon us, and in the spirit of giving, Mix Master Mitch has graced us with his latest rap video. This time around, Mitch decided to focus on setting up NetFlow on a Cisco Catalyst 6509 switch. Take a look.

Mix Master Mitch was also kind enough to give Systrax an exclusive interview. It was hard to pull him away from his legion of screaming fans, but he managed to sneak off for a few minutes to give us his insight on his latest creation.

Happy Friday everyone!

The other day I was working with a new customer getting NetFlow export enabled on his Cisco 3800 routers. When I was explaining the concept of using the ip flow ingress command in enabling NetFlow per interface, he said:

“I have to do that on all my interfaces?!? I have like ten sub-interfaces to do.”

In reality, ten interfaces isn’t really hard to configure, but it can be… cumbersome.

So if you are enabling NetFlow on a device with LOTS of vlans, a nice quick way to get things up and running is to use the int range command.

You can do this by typing the following:

Last week I blogged on Upgrading to Scrutinizer v7.2 NetFlow & sFlow Analyzer.

We have had such an overwhelming response from both existing and potential customers for this version of our network monitoring application that we are now sending the upgrade instructions to customers to allow them to upgrade at their leisure.

It has been very well received, as it now allows customers to schedule their upgrade to non-business hours if necessary. Also, for customers with secure servers without Internet access and unable to allow us to use remote access software (we use GoToMeeting), they can now perform the upgrade on their own and enjoy the new features of Scrutinizer.

Hi there guys! Great news this week. We’ve decided to start beta for the first phase of our NetFlow migration tool.
With this simple tool, we’ll be able to take all your NetFlow v5 records you collected from Scrutinizer v6 and be able to migrate them over to the new Scrutinizer v7 format.

We’re going to start this migration test one bite at a time, since your archived NetFlow and sFlow database integrity is important to us.

I’ve seen some really incredible Network Topology maps out there and I’m sure there was significant time invested to make them that way. So lets start out by making life easier and let our network traffic map migration tool move them over for you!

If you’d like to volunteer and help me beta test the migration, I would love to help.
Call our customer support desk at (207) 324-8805 ext. 4 and we can schedule a time to get things going.

PS: The migration BETA is for the Flash maps only. The google map integration needs a few more tweeks. We will be announcing the release of the full database migration tool at a later date once internal testing has come to a completion.

We released another free utility yesterday called Flowalyzer. The Flowalyzer NetFlow & sFlow Tester is a free NetFlow and sFlow Tool Kit for testing and configuring hardware and software.

Flowalyzer can help you troubleshoot hardware from vendors like Cisco and Enterasys, as well as testing the NetFlow collector software, to ensure that both the hardware and software are configured correctly.

OK, let’s say you’ve decided to live a healthier life. You’re exercising regularly, stopped getting drunk every night, and you’re eating healthy. You’ve been eating more salads, almost cut out red meat, and even eating annoyingly healthy desserts, if any. Read more »

This is Brighton. He is currently 3 1/2 years-old and he’s my son. He’s very much like his mother, with a strong will and a fierce determination that will make him successful in about anything he does.

However, that same determination also sometimes makes his parents want to carve their brains out with a spoon.

He’s at that stage where he will repeat the same thing over and over and over and over until everyone immediately stops what they are doing to address his needs.

I had a customer ask me how HP Procurve’s Class of Service (CoS) for VLANs could be monitored in Scrutinizer with QoS (Quality of Service).

HP Procurves export sFlow (sampled flows). Scrutinizer v6.05 listens to sFlow counters and samples. If specific VLAN tag information is sent out, Scrutinizer ignores it in the current release.

What the sFlow collector (e.g. Scrutinizer), does see is the ToS (Type of Service) byte included in the sFlow packet. The values for this 8-bit field can be defined in Scrutinizer in the QoS Definitions option in Settings. The QoS Definitions feature allows network administrators to customize their QoS settings, with the ability to run reports based on the 8 bit ToS values or 6 bit DSCP values.
