Can scopeSpans fields be automatically configured?

[huangtao730]

“ScopeSpans” does not have some fields I need such as local ip. Can I get these field information through parameter configuration?Or do I need to modify the source code to get it?The structure of “ScopeSpans” is not what I want. Can I modify this structure to suit my needs?If so, what do I need to do?Tks

Can you get them from span in ScopeSpans? If current design can't meet your demand.
The definition of ScopeSpans comes from https://github.com/open-telemetry/opentelemetry-proto/blob/2bd940b2b77c1ab57c27166af21384906da7bb2b/opentelemetry/proto/trace/v1/trace.proto#L68-L83
If you have any suggestion or modification, you need to file an issue in related repo.

We are currently using skywalking and now want to change to opentelementry。So there are many compatibility issues that need to be considered。
I also can't get the fields I want from the "spans" in "ScopeSpans", such as the remote IP and port of the httpclient component.
Secondly, our traceId is generated according to a certain strategy. Can the generation logic of traceId here be modified?For example, this is our current traceId:"5a0a0a651df8d17351813345470620"。Bits 1 to 4 represent the process ID, bits 5 to 13 represent the machine IP code, bits 14 represent the environment code, bits 15 to 28 represent the timestamp, and the last 4 bits are an auto-increment number used for modulus sampling calculations.
Therefore, we need to modify the traceId generation specification to be compatible with our current old version of APM。
Any good solution? Tks！

Can you elaborate where you want to get attributes like remote IP and port in span? In your application or elsewhere?

You can do it by using a custom IdGenerator, refer to https://github.com/open-telemetry/opentelemetry-java-instrumentation/tree/main/examples/extension#extensions-examples
