As per @Remy 's comment [here](https://discuss.daml.com/t/logs-in-canton-nodes-domain/5562/2), I’ve enabled DEBUG at the root level on the command line, and I can see error messages such as:

```haskell
2023-03-16 09:54:37,958 [grpc-nio-worker-ELG-3-5] DEBUG io.grpc.netty.NettyServerHandler 

```

So perhaps It’s just the logger name that is incorrect (i.e. `io.grpc.netty` instead of `io.netty`) [edit: no, that didn’t help]
