Looking for a reliable bandwidth utilization NetFlow billing system?  If you are already using Cisco NetFlow technology for network monitoring and management, then it’s just one more simple step to extending that to bandwidth billing.

Using the Service Provider Module for Scrutinizer NetFlow & sFlow Analyzer and a customized Billing Module, you can monitor the bandwidth usage of your customers and also provide  a data export to your current billing application.

The Service Provider Module allows you to restrict your customers to view specific devices and/or interfaces in Scrutinizer. The “Scrutinizer v7 NetFlow and sFlow Analyzer: Using the Service Provider Module” blog has more information on this module’s features.

The Billing Module is a customized solution using the enhanced features of the Service Provider Module ad importing that data into your billing application.

A custom data file (i.e. saved report filter) is created and exported every hour, giving the most granular data (1 minute intervals) available. The data file can include but is not limited to:

  • Time Stamp
  • Rate: bytes / second
  • Peak: same as above when reporting at 1 minute intervals
  • Totals: total bytes per minute


Any NetFlow or sFlow exported field can be included (bits, packets, percent, IP/MAC addresses, VLAN ID, applications, ToS, Autonomous System, etc.) if required.  The billing application or script can then read in the files exported by Scrutinizer at a definable interval.

You should also know that Flexible NetFlow using a Permanent Cache can also be used for importing data into your billing application.

If your billing application is based on 95th percentile measurements, this information is also available in the Traffic Volume report displayed below.

95th percentile billing allows for the top 5% of spikes in a given period to be dropped from the utilization reported.  In the example above, 95th percentile for Inbound is 99.78% and Outbound is 24.81%.  This report is based on a one hour timeframe, providing both Inbound and Outbound traffic for the T1 interface.

Interested in using Scrutinizer to get the data for your bandwidth billing?  Contact Plixer Sales at 207-324-8805 x3 for more information on this custom solution.

Apply Names to NetFlow Templates

Posted in NetFlow on March 13th, 2010 by mike@plixer.com
apply-names-to-netflow-templates

Scrutinizer v7.6 has been released.  One of my favorite features is the ability to rename NetFlow v9 templates, IPFIX templates and Flexible NetFlow Templates. We had to provide this feature since Cisco NetFlow does not export the template name.  Do you know why this is such a cool feature? Read more »

upgrade-your-network-maps

Thinking outside of the box can produce some innovative ideas.

While the network maps in Scrutinizer can make the traffic flow on your network easier to visualize and congested links quicker to spot, adding more visual definition to your maps will make them more user friendly and understandable by more members of your organization.

So how do you spice up your NetFlow data and breathe some life into your network utilization maps? Try combining a tool created for home design with a network monitoring tool to create incredible network maps.

Upgrading to Scrutinizer v7.2 NetFlow & sFlow Analyzer

Posted in NetFlow, NetFlow Analyzer, Network Traffic Analysis, Network Traffic Monitor, Scrutinizer, sFlow on November 3rd, 2009 by Jo-G
upgrading-to-scrutinizer-v7-2-netflow-sflow-analyzer

Late last week, we announced the version 7.2 release of Scrutinizer NetFlow & sFlow Analyzer, which includes data migration from Scrutinizer v6.

If you’re currently running version 7 of Plixer’s NetFlow analysis tool, then moving to v7.2 is a simple incremental upgrade.

However, for those customers who have been waiting anxiously to upgrade from version 6.x to v7, this is a major release and we want to make sure that using this network monitoring tool remains as pleasant an experience as ever.

For that reason, among others, we are assisting with the upgrades from Scrutinizer v6.x to v7.2 in these first few weeks of this release. And so far, it has been a relatively seamless process with delighted customers as a result.

Cisco ASA NetFlow supports bidirectional flows

Posted in ASA, NetFlow, NetFlow Analyzer, Network Health Report, Scrutinizer on October 14th, 2009 by jimmyd
cisco-asa-netflow-supports-bidirectional-flows

If you are running Scrutinizer v7.01, the Cisco ASA interfaces don’t show up in the Status tab yet. It was a philosophical decision. Here’s why:

The ASA running v8.2.1 exports bidirectional NetFlow!  This is unlike anything else we’ve seen.  In nearly all NetFlow exports v5, v9, IPFIX etc. flows are exported in one direction (i.e. A -> B and then a separate flow for B -> A).   This is true for ingress or egress NetFlow. For Example: lets say A -> B creates a flow of 200KB.  Then in return:  B -> A causes a 2nd flow of 40KB. Well, the developers of the ASA decided to be unique and add the two flows together and export A -> B 240KB!!!!  The two added to each other is called a bidirectional flow.

Because of this, when we calculate the percent utilization using NetFlow (i.e. not SNMP) by adding the total flows together we overstate InBound/OutBound utilization in the Status tab. We are talking with Cisco about this unconventional export method. We have no definitive news yet.

NOTE: The ASA also doesn’t support an Active Timeout causing huge spikes in the graphs and thus making network traffic analysis kind of tricky when traffic that occurred over several minutes shows up in a single minute!

If you are seeing some screwy results with ASA and NSEL, the above is why. Anyway, everyone can blame Mike for not sticking the data in the Status tab!

Here is a pic of our  ASA:

Need help configuring NetFlow export from the ASA?  You can also setup NetFlow exports up using Cisco ASDM. Make sure you have watched the Cisco ASA and NetFlow training video.
