How to list all flows during specified time interval?



Your Vote:



Hi guys, PRTG is a great product that I have been using for years in various implementations.

I have a current need to collect, list and identify all network connections made to/from a specific network in my company for auditing purposes and planning of a future firewall installation. I have enabled NetFlow from our core cisco switch and connected it to PRTG, this works just fine. However I need to be able to list ALL connections to/from the network in question, not just top talkers. Bandwidth use is not of interest for this purpose.

I enabled log stream data to disk and checked the CSV file, this contains all information that I need in a raw format. So it would seem that PRTG has all the information it needs for making a great connection diagram or summarised report. Is PRTG the right tool for this or should I look elsewhere? If so, I would be happy for any suggestions. =)

Best regards Jonas Eriksson

Dear Jonas

The logging serves as a debug option. PRTG has no netflow reporting (despite the bandwidth for pre-defined filters) implemented. PRTG cannot show all flows, or all connections over a time interval. Due to performance constrains, please don't expect such reporting in the foreseeable future.

PRTG 16 has some nice netflow monitoring capabilities including custom filter options and top lists, but it is not a full-blown netflow monitoring suite.
