Apache JMeter Test Script Recorder gRPC HTTP/2 support

I want to load test a web application server which communicates through gRPC (which uses HTTP/2 for transport) with the clients.

It seems that Apache JMeter extended by the plugin JMeter gRPC Plugin and JMeter gRPC Request sampler would be perfect for this.

Among other things JMeter provides a Test Script Recorder which helps quickly generate scenarios by acting as a HTTP proxy between the client and the server.

Question 1: Is it possible to use the JMeter Recorder for recording the communication through the gRPC protocol?

Question 2: Is it possible to use the JMeter Recorder for recording the communication through the underlying HTTP/2 protocol?

I have tried already the JMeter Recorder to record the gRPC communication without success :-( Maybe caused by wrong configuration of the recorder?

Solution
    1. No, at least not with JMeter 5.5
    2. No, as of JMeter 5.5 the HTTP(S) Test Script Recorder doesn't support HTTP/2. Neither it does support .proto files so even if you record the raw packets you won't be able to decode them into anything meaningful

    So I would recommend using a sniffer tool like Wireshark for capturing the packets between client and the system under test and then replicating the same using JMeter's GRPC sampler.
