@vitorenesduarte mentioned:

It’s possible to filter logs by application. For example, RUST_LOG=hyper=info would only should logs for hyper.
(Nevertheless, the first line “Message CreateClient for…” in the log above doesn’t seem to come from tracing, so this probably won’t help)
...
it’s also possible to say something like RUST_LOG=app1=info,app2=debug

I thought that the RUST_LOG would work but apparently there are some messages (see below) that use status_info! macro from abscissa and that seems that it doesn't use log or tracing. So not sure there's a way to control, seems a custom macro.
