Traefik Pilot shows insane request durations

I recently set up Traefik Pilot because I wanted to use some plugins (which seems like a very complicated way to do this). Looking at the statistics, I'm seeing crazy-looking values for request durations - like, "25.8k ms" and more. I suspect that this is because it's seeing websockets (one of the proxied web apps is Mattermost) as being a really slow-to-complete web request.

Is there any way to make the stats a bit more fine-grained, and disregard certain requests?
