HI guys I have followed this tutorial : https://signoz.io/docs/install/linux/ Everything seems running but nothing in the dashboard in metrics. Where can I check for data in the DB or to see if the collection work ? I can see the log's colletor saying :

Apr 14 16:30:34 FRPAR3DXSBOX signoz-otel-collector[11717]: {"level":"info","timestamp":"2025-04-14T16:30:34.858+0200","caller":"opamp/server_client.go:171","msg":"Waiting for initial remote config","component":"opamp-server-client"}
