What are the system requirements?

How is NetFlow different from traffic analyzers like MRTG?

MRTG and other such equivalent tools provide information that is largely limited to SNMP statistics. NetFlow is more geared toward application-level details such as hosts, protocols, and conversations, which are an inherent part of IP traffic.

Is Cisco the only vendor supporting NetFlow?

NetFlow technology was invented by Cisco, and Cisco IOS devices offer NetFlow compatibility. There may be other vendors offering NetFlow support on their devices. Scrutinizer has been tested on over a dozen different vendors.

Is a trial version of Scrutinizer available for evaluation?

Yes. A free version of Scrutinizer can be downloaded and you can get an evaluation license to try the full version.

What are the differences between the free and commercial version?

The commercial version of Scrutinizer NetFlow & sFlow Analyzer includes the Flow Analytics add-on module, which adds historical data retention and network behavior analysis.

Scrutinizer's system requirements are detailed here: System Requirements

How do I find out if my Cisco equipment supports NetFlow?

Review the NetFlow Services Solutions Guide to find out if you have a NetFlow compatible Cisco router or switch.

What if I need features that Scrutinizer does not support?

We understand that our software needs to be flexible. If you want a feature added, we may be able to work with you.

Does it support other Languages?

Scrutinizer currently supports the following languages; Chinese (Simplified and Traditional), English, French, German, Japanese, Korean, Portuguese, Russian, and Spanish.

How will enabling NetFlow affect the performance of the router/switch?

For detailed information on exactly how enabling NetFlow will affect the performance of your Cisco router or switch, review the NetFlow Performance Analysis whitepaper [PDF]: http://www.cisco.com/en/US/technologies/tk543/tk812/technologies_white_paper0900aecd802a0eb9.html.

How long do I have to wait before the graphs are populated?

Less than 5 minutes. Make sure you have the NetFlow configured correctly on the router or switch.

Why are some interfaces labeled as IfIndex2, IfIndex3 or just 1, 2, 3, etc.?

This happens if the interfaces did not respond to the SNMP requests sent by Scrutinizer. Bring up the SNMP view that lists all the interfaces and click the Update button. Please review SNMP Device View in the Scrutinizer manual.

Also, this will occur if flow option templates to identify the interfaces have not been received.
