Is the log collecting means Span::add_log?

If yes, it's already done.

[wu-sheng]

No, it isn't. Log collecting mean logs with trace context could be reported through grpc log API. It is less expensive than including in spans. Also, you would be able to search logs without trace ID.

[jmjoy]

For logging, I want to implement it by integrate with the tokio log framework tracing, add the grpc subscriber and some filed in log, such as:

// The GrpcSubscriber implement `tracing::Subscriber`.
let subscriber = skywalking::logging::GrpcSubscriber::new();

tracing::subscriber::set_global_default(subscriber);

let trace_context = create_the_trace_context();

info!("some log", skywalking.ctx = trace_context);

Because tracing is not only a log framework, but also a trace framework, so in the future, I want to integrate skywalking Tracer with tracing, like tracing-opentelemetry.

[wu-sheng]

You could create APIs fot native logging/tracing integration, and provide a shell on the APIs for tokio tracing. This would be helpful to set up APIs boundaries.

I have some doubts about metric, where will the metric data be displayed on the UI?

Nearly all data on the pages? You need to follow MAL to pre-process metrics

You could take a look for k8s, virtual machine(linux), and MySQL server monitoring.
