@SergeyKanzhelev You seemed to have a strong opinion on #709, so please take a look at this proposal.

Should we also add OTEL_SERVICE_VERSION or add a note that service.version can be set via OTEL_RESOURCE_ATTRIBUTES?

I usually prefer to keep PR scope small, if possible. This PR solves one specific issue. I am happy to file a follow-up one, if you feel this is needed :)

That's reasonable. If we add it, it would ideally be in the same spec version, however, so SDK maintainers/implementers can tackle this tightly coupled feature at once. The next release is scheduled for early June, so we should be good here, as the follow-up should be as uncontroversial as this PR.

Same as #1677 (comment): I don't think the service version is used often enough to warrant it's own attribute. We did receive user requests for service.name AFAIK, but not for any others.

I am ok with the suggestion, but before merging, let's clarify whether environment variable should take precedence over the value set in code.

Question that is not answer:

Why service name is treated differently than any other resource attribute?

Question that is not answer:

Why service name is treated differently than any other resource attribute?

It is the only de-facto "required" resource attribute
The majority of vendors already have similar variable (Add OTEL_SERVICE_NAME env variable #709 (comment)), so this is what end-users already expect
This PR does not preclude any other PR which adds support for other resource attributes.

Based on #1677 (comment) I will submit the PR about OTEL_SERVICE_VERSION after this one is merged.

iNikem · 2021-05-14T07:58:03Z

@bogdandrutu as discussed during spec SIG meeting, I tried to stress the significance of this specific attribute. Please check my changes in README.md

 ### SDK Configuration

+- Add `OTEL_SERVICE_NAME` environment variable. ([#1677](https://github.com/open-telemetry/opentelemetry-specification/pull/1677))


I have never heard of anyone using namespace (but maybe it just works so well that there are no questions?). instance.id has is currently IMHO too vaguely defined to be useful, as discussed in #1034. So the service name is IMHO definitely the most useful one.

@bogdandrutu ;)

Personally still believe we should not make this special but I would let the majority decide, I would not block but disagree with the change

iNikem · 2021-05-23T07:18:07Z

@open-telemetry/technical-committee Anybody feeling confident enough to merge this?

carlosalberto · 2021-05-24T13:52:23Z

@bogdandrutu Thanks for going on with the compromise, really appreciated. Merging (we will see in the long run how things unfold! ;) )
