Ensuring Consistency between service.instance.id and instanceId in opampextension

Is your feature request related to a problem? Please describe.

While using opampextension, I found that when I wanted to query self-monitoring metrics and only knew the instanceId but not the service.instance.id, due to the inconsistency in their values, I was unable to query using instanceId.

If it were possible for instanceId and service.instance.id to be kept consistent as they are in opampsupervisor, then it would be convenient for me to query using the instanceId.

Describe the solution you'd like

"Considering the OpAMP and OTEL specifications, where instanceId must be a ULID and service.instance.id is recommended to use UUID, I suggest the following:

1. service.instance.id uses ULID by default
2. opampextension directly reuses service.instance.id without setting the instanceId configuration item.

Describe alternatives you've considered

Thanks for the detailed write-up. I will have to think over the solution more, but I think this is valid.

FYI, we may move from ULID to UUID in opamp too: open-telemetry/opamp-spec#186
