Hi Slame, welcome!
The bandwidth chart in the node dashboard doesn’t update instantly, so it will take time to populate (this metric is sent from the satellites to the node). If your node is online and storing data, everything should be fine. The disk space used graph data is populated directly from your node, so seeing space used here is good. You could also check your node logs for successful upload messages.
If you wish, you can check your node’s vetting progress with this community tool made by BrightSilence:
Keep in mind that vetting will take some time, and the progress accelerates as your node stores more data.
