Sorry if it is a stupid idea, but cannot you log all messages to a separate file for each test (or attach test id to the messages)? Then if the test fails, you can see where the error occured.

Where I work there are 1,500 microservices. How do I get a log of all of those services -- only related to my test's requests in a file?

I know there are solutions for this, but in the real world I have not seen it properly implemented.

As you said, OpenTelemetry and friends can help. I had great success with these.

I am curious, what were implementation issues you have encountered?

This works easily enough in the major cloud environments, since logging tends to be automatic and centralized. The only thing you need to do is make sure that a common request id or similar propagates to all the services, which is not that difficult.
