Gatling 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 Gatling extended by the plugin Gatling-gRPC would be perfect for this. Among other things Gatling provides a 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 Gatling Recorder for recording the communication through the gRPC protocol?

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

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

Solution

  • No, it's not possible to record gRPC with Gatling's recorder atm:

    • it doesn't support HTTP/2
    • it doesn't support gatling-grpc which is a third-party plugin work (there's some ongoing work to contribute it upstream)
