Is there something in the web console I could check or do I need to check this from my server?
So to see the IPs that Solarwinds have reached you do this:
1) login into your server
2) Go to Database manager: Start menu\Solarwinds Orion\Advanced Features\Database Manager
3) Click "Add default server"
4) Expand your default server, expand SolarWinds Orion, double click "NodesData"
5) Click "Execute query"
6) All the IPs with extra info will show up in the table underneath.
