Cadvisor / prometheus logging stops at night

[Str1atum]

Hi,

I got a strange issue with a pretty basic cadvisor/node-exporter/prometheus/grafana docker setup.
My stats for the cadvisor part stop from 0 to 6 am and show a complete flatline. Stats from node-exporter continue during that period. Neither my server nor my network is offline during that time. Docker setup is basic just setting volumes and ports.

Is there some kind of sleep setting that I don't see or any other ideas?

Thanks!
