I'm having trouble with NTA not showing the proper times, and it appears to default to the last 15 minutes no matter what I do. I've tried changing it from different tabs, showing a relative time period and even a named period of say, 2 hours past. It always ends up showing the last 15 minutes. Is this is a default setting I can override somehow, or a bug? I've also tried checking using our superuser account, so it does not appear to be a permissions issue. The graph data shown only shows the past 15 minutes, I can't adjust the bar, either.
