Great News for all who were looking for monitoring NetFlow data from Cisco ASA devices. ManageEngine NetFlow Analyzer now provides preliminary support for NetFlow data from ASA devices.

For those who have not caught up on this news, a couple of months back, Cisco released a new IOS which brings support for NetFlow capabilities to ASA devices. The NetFlow feature from ASA devices, termed as NetFlow Secure Event Logging (NSEL), is based on NetFlow version 9 flow format and can give real time bandwidth reports.

Ever since this release, we have had a huge demand to start supporting the new flow format. Working with some customers who provided packet captures from their ASA devices, our engineering team has successfully developed a patch which would provide support for these flows. The patch has to be applied on top of the latest version of NetFlow Analyzer.

This patch enables NetFlow Analyzer to report on traffic and bandwidth information using the NetFlow packets from ASA devices when exported in the same format as NetFlow version 5. We will be extending our support to the new fields in our next release.

You can find the recommended configuration for ASA NetFlow from this post in our forum. Please contact our technical support at netflowanalyzer-support@manageengine.com / +1 925 965 9435 to get more information.
