Get logs outside lora app server


When one is doing an joinRequest, with an device and the lora server, one could see the errors in the lora app server logs.
Like this:

Blockquotetime=“2019-03-19T11:08:40Z” level=info msg=“finished unary call with code NotFound” error=“rpc error: code = NotFound desc = object does not exist” grpc.code=NotFound grpc.method=Get grpc.service=api.DeviceService grpc.start_time=“2019-03-19T11:08:40Z” grpc.time_ms=4.115 peer.address=“” span.kind=server system=grpc

My question is if there is any other posibilities to get that information elsewhere?
