Insight data is blank - either shows a flat line, or only LAN traffic

[drivera]

Hi!

I've noticed recently that my Insight graph screen never has any significant data. I tried resetting the RRD and Netflow Data, but to no avail.  I tried manually running the flowd_aggregate service, but it didn't fix anything.

I've been looking through the logs but I'm not sure what to look for. I don't even know if the Insight data is populated from the netflow data or somewhere/thing else entirely.

Importantly: I've tried doing a data reset and immediate reboot and sometimes it would work and everything starts to show as expected, but it's since stopped working.

To clarify: the "Traffic" section does show real-time traffic. It's the historical stuff that is borked, and I'd like to fix.

Can you guys help me figure this out? Is there any way to fully, cleanly, atomically reset the graphing data so the engine starts gathering stuff correctly again as if from a fresh install?

Thanks!
