I need a Top 10 Conversation report on a single link 24 hour period

Do you have NTA?  If yes, use the explorer to build what you want.

Yup sure do. I've selected Netflow Flow History and picked the ones I want, but then I get that error.

Can you make up what you want with Flow Navigator?

On the NTA Summary page Look for the "Flow Navigator" on the upper left-hand side of the web page.  Click the ">>" to expand it.

Make your query.

When done. At the bottom of the Flow Navigator click [SAVE FILTERED VIEW TO MENU BAR]

I did this the other day to make a top talkers list for a class of WAN circuits.  The duration I used was a day.

I hadn't seen that before, thanks! But I need it just for 1 circuit and to have the report emailed out each day so using Flow Navigator doesn't look like I can achieve that. Or have I missed something?

Thanks!

Does it have a range of IP's as a source or destination?

You could make an IP Address group Converstations...  From 172.16.0.1 - 172.16.255.0.

Maybe someone else can jump in for an emailed report but I know you can make an alert on Flows.

Open Flow Navigator

In "View Type" select "Detail"

Put "Node" in the top box.

Select the node at the endpoint in the second box. 

After you hit Submit see if you can make a report out of that data.

It is getting late here...I hope this helped out some.

When you select ADVANCED for each column, what is the DATABASE COLUMN you see?

It doesn't appear the the NodeID lets you get at the Network Interface ID of the source. At least at first glance. Using the concept Radioteacher​ proposes works ok, but it may give you more than you want. Especially if there are more flow sources providing data about those IP Groups. But it gets you there.
