Possible to monitor Power BI on-premise gateways with Solarwinds?

Hi! If so, I think this would be a custom application template. Do you have SAM or Hybrid Cloud Observability? You can build custom application monitoring to monitor through the Platform. If you have one of those products and aren't familiar with building custom templates, we have classes on the customer portal that can assist you. Also, here is a SAM document that discusses building custom application monitoring. I hope that helps!
