Hey,
my storagnodes are linked to the storagenode exporter + graphana.
In the last weeks i see strange activities, mostly in the german morning hours.
As you can see in my screenshot the egress transfer rates peaks up to 150 Megabit per second.
Grafana has it’s own calculation in the dashboard table. Have you confirmed it’s the correct calc?
Additionally, maybe other services on the machine are utilizing the upload. Or, it’s capturing garbage collection or other local disk scanning / cleanup.
