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.

NetFlow Analyzer shows only last 24-hr data
I just installed NetFlow Analyzer Free Edition a few days ago. I notice that the charts show the data ONLY for last 24-hrs, even if I select longer time period, like last 7-days, 30-days or Custom. I am on build 12200 and was told to apply the latest fixes and I did. Issue still remains that I cannot see data older than 24-hours. Any help will be appreciated.

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). I made a separation in the widget (clicking one of the values of input and output) and this would work for me but when it refreshes, put it back all the data out or in. The NFA version is 12200 is mounted in win 2008 r2 I attached

Netflow is not populating, corresponding error in Stderr
Trying to get netflow working for some devices, we know that netflow is being recieved by Opmanager, but the Netflow page for the flows never poplates. If you look at the interface, it shows as purple and shows snmp uknown, despite the device SNMP credentials being correct and verified. This started happening around the same time OpManager started throwing an error in its stderr logs: :921]|[03-22-2017]|[SYSERR]|[INFO]|[399]: java.lang.NullPointerException| [10:38:37:921]|[03-22-2017]|[SYSERR]|[INFO]|[399]:
