I have attempted to configure Netflow on a Cisco ASA 5555. I have done this numerous times without an issue but I seem to have an odd issue this time
I can see from the ASA that the netflow data is exporting properly and I can see the data within the opsview dashboard as well. I am nicely graphing the data and can see top host transmitters and top host recivers perfectly. The issue is that the 'top transmitters' widget is not working and just shows 'no data available'. you can also normally get to this view from clicking a point on the graph, but although I can see the graph and the peaks and valleys fine, when i click a spot on the graph it pops up with the top transmitters window but again just presents the 'no data available' message
i have never seen this behavior. I have seen where netflow as a whole just doesnt work due to various configuraiton issues but never where it mostly works but a single widget or view does not.
Has anyone experianced this before? Anyone have any idea what is causing this?
Thanks for any help you can provide
