A good way to get an inventory report?
Hi, I'm struggling to find a good way to generate an inventory report of all devices in NFA. Compared to Opmanager or NCM there are pre-built inventory reports that are very good and informative. In NFA 12.2 there doesn't seem to even be a report for this information. Is it possible to generate this with a DB Query?

Webinar: Why do you need Deep Packet Inspection for bandwidth management.
Hello everyone, Deep packet inspection capabilities rely on packet-level analysis to determine whether the network or the application is at fault and react quickly to the issues before it impacts the end users. In order to maintain a proper balance between user experience and bandwidth management, deep packet inspection is introduced in NetFlow Analyzer. It helps to simplify the task of identifying the exact root cause of faults and to keep control on bandwidth usage. Please join us for the webinar
Inaccurate link useage showing in Netflow Analyzer
Hello All, I am not very well versed in Netflow Analyzer but managed to get our key Nexus switch interfaces sending data to our server. Unfortunately the size of the traffic looks way to small. For instance, a WAN link is showing a peak of only 19.65 kbps. I know this is not accurate. I'm wondering if there is a setting change I need to make in Netflow Analyzer or if I need to make a change to the way netflow is setup on the switches. Any help is appreciated. Thanks. Jim L.

Traffic widget is summarizing data
Hello everyone I need your help to create a view that shows the traffic in and out of a monitored interface. I have generated it through the widgets but it does not show me the real data (apparently this is summarizing the data since the traffic of output is Less than input).

The NFA version is 12200 is mounted in win 2008 r2 I attached

Netflow is not populating, corresponding error in Stderr

NetFlow plugin upgrade
I am upgrading my OpManager and NetFlow Analyzer and I have an issue. My OpManager was 9200 and NetFlow was 9000. I updated the OpManager to 9410 and at the end of the process it said to upgrade NetFlow BEFORE starting OpManager. However, when I tried to update the NetFlow using the 9000 to 9700 ppm file it says that is not compatible with what I have. I've downloaded all the files for each to get me current but I am stuck on my second step. Any help would be appreciated, sooner the better. Thanks
