If you are talking about the column

Operation

in trace filter page, I don't think SigNoz plays around with it. We analyse different span attributes to create a sensible value for the columns

Method

and

Status Code

keeping in mind http and grpc calls. Are you talking about differences in latencies? Latency usually has nothing to do with what the attribute values are and how are they stored. Can you please be more detailed here? cc: @Vishal Sharma

Sorry to be clear I am focused on the method column. It seems that the go and python instrumentation do not set the attributes the same and therefore the go dynomo db calls do not fill in the methods column. The go sets the method in aws.operation even though the instrumentation should be same between languages. Since it’s not is it reasonable for SigNoz to consider aws.operation attribute as a method as well or should I manually inject our spans with the rpc.method?

The instrumentation libraries are not mature yet, so they will have differences. It is indeed an rpc call under the hood. You may want to open an issue here and get that fixed https://github.com/open-telemetry/opentelemetry-go-contrib/tree/main/instrumentation

Thank you
