Hi,

This are to people who have cisco netflow enabled on their router. Il like to know what netflow analyzers people are currently using.

I am currently looking into NetQos report analyzer. Is there anyone currently using this? If they are what do they think of the product?

Anyone please just list what product or open source tool they are currently using to analyze netflow data and why?

thanks

regards,
gab

MRTG isn't applicable here, although I suppose if you use a flow collector to write data to a file you could massage the data into MRTG or RRDTool format...

CAIDA has a whole page of tools that includes a bunch of netflow tools ... but I can't seem to find it at the moment. :-( Here's one they're directly involved in, NeTraMet:

Haven't yet had time to try it myself.

Hello,
I'm using nice netflow implementation: Caligare Flow Inspector - http://www.caligare.com/ We are fully satisfied, because they have implemented some our ideas in to this linux software.
They have monthly updates, witj many new features, so I'm like that we bought CFI.
And want we like:
- customized flow fields
- pretty web interface
- customized user rights and restrictions
- many trend statistics
- heuristic application recognizer
- LDAP authentication
- perfect search condition specification

I think that there is many others, so
these are important for me. I heard that
network anomalies detection will be implemented this year.

Bye, Peter

My customers just fall in love with www.netflowanalyzer.com This is one of the fanciest Netflow software I have seen. The price is also amazing low. Free for 1 router (2 interfaces)
Other one http://www.paessler.com/prtg came to market as friendly MRTG clone. I found now that they are supported NetFlow (personally I'm only tested SMTP counters some time ago). Free for 3 sensors (i guess routers).
Both products are single click install and very user friendly.

Personally I'm looking for a product to graph NBAR statistics. A lot of modern apps use dynamic ports (P2P, Skype, etc) and can be accounted only with NBAR.

Just for you info. Here is the tool to poll and graph NBAR MIB - http://www.somix.com/products/denika_nbar.php This product use MRTG but wrapped to a user friendly setup and config wizard.

What are peoples thoughts on good sflow analyzers? The built in PCM graphs aren't great. Ideally I'd want something like Netflow Manager for sflow.

We've tried Inmons free sflowTrend - nice but can't afford the full product.

Hi,

NetFlow Analyzer from ManageEngine is a solution that has been in the market for sometime. Has very good features and is priced much lesser than those with much lesser features.Try NetFlow Analyzer from ManageEngine at www.netflowanalyzer.com

Hi,

I think one of the best Netflow Analyzers out there is the WANGuard software from www.andrisoft.com. It allows you to monitor traffic through NetFlow or Port Mirroring, and also protect your network from DoS & DDoS attacks.

Try SolarWinds Orion NetFlow Traffic Analyzer (NTA).
It Identifies which users, applications, and protocols are consuming the most network bandwidth and highlights the IP addresses of the top talkers on the network and Maps the traffic arriving from designated ports, source IPs, destination IPs, and even protocols, to application names you can easily recognize.
