Summary

Adds consistent hostname reporting across spans, OTLP trace resources, and OTLP trace-metrics resources.

  • Treats DD_HOSTNAME as a core configuration key. A nonempty value overrides the system hostname.
  • Uses the same resolved hostname for the root span _dd.hostname, OTLP trace resource host.name, and OTLP trace-metrics resource host.name.
  • Gates all hostname emission with DD_TRACE_REPORT_HOSTNAME; child spans do not receive _dd.hostname.
  • Keeps JSON and protobuf trace-metrics output aligned.

This draft is stacked on #8992 and must merge after it.

Validation

  • Focused HostMetadata, OtlpMapper, and OtlpSpanStatsSerializer tests: 127 passed on net10.0
  • Datadog.Trace build across net461, netstandard2.0, netcoreapp3.1, and net6.0: 0 warnings, 0 errors
  • git diff --check: passed
  • Earlier fresh system-test artifact: 38 passed, 8 XPASS, 4 expected XFAIL, 2 skipped, 0 failures
  • test_fr06_10_hostname: XPASS
  • test_fr06_11_hostname_omitted: passed

Fix OTLP trace metrics attribute gaps in span stats serializer
4e5571d 
- status.code: fix protobuf path to emit the OTel string literal
  (STATUS_CODE_OK/STATUS_CODE_ERROR) instead of an int enum, and make
  it unconditional in both JSON and protobuf paths (was previously
  omitted on non-error data points).
- is_trace_root: emit datadog.is_trace_root next to
  datadog.span.top_level, gated behind OTel-semantics suppression like
  other datadog.-prefixed attributes.
- additional_metric_tags: emit each configured key as its own
  unprefixed data-point attribute, never gated by OTel-semantics.
- span.kind: canonicalize to the uppercase OTel Span Metrics Connector
  convention (SPAN_KIND_SERVER, etc.) via a lookup table.
- process_tags/peer_tags: leave a TODO comment; not wired into OTLP
  output this round.

fix(otlp): always emit data-point-level service.name
e912b4d 
Previously omitted when it matched the resource-level default,
inconsistent with status.code and other data-point attributes
which are always present.

Benchmarks

Benchmark execution time: 2026-08-07 18:39:04

Comparing candidate commit a37e943 in PR branch codex/otlp-trace-metrics-hostname with baseline commit 7a4fb69 in branch master.

📊 Benchmarking dashboard

Found 0 performance improvements and 2 performance regressions! Performance is the same for 70 metrics, 0 unstable metrics, 66 known flaky benchmarks, 60 flaky benchmarks without significant changes.

Explanation

This is an A/B test comparing a candidate commit's performance against that of a baseline commit. Performance changes are noted in the tables below as:

  • 🟩 = significantly better candidate vs. baseline
  • 🟥 = significantly worse candidate vs. baseline

We compute a confidence interval (CI) over the relative difference of means between metrics from the candidate and baseline commits, considering the baseline as the reference.

If the CI is entirely outside the configured SIGNIFICANT_IMPACT_THRESHOLD (or the deprecated UNCONFIDENCE_THRESHOLD), the change is considered significant.

Feel free to reach out to #apm-benchmarking-platform on Slack if you have any questions.

More details about the CI and significant changes

You can imagine this CI as a range of values that is likely to contain the true difference of means between the candidate and baseline commits.

CIs of the difference of means are often centered around 0%, because often changes are not that big:

---------------------------------(------|---^--------)-------------------------------->
                              -0.6%    0%  0.3%     +1.2%
                                 |          |        |
         lower bound of the CI --'          |        |
sample mean (center of the CI) -------------'        |
         upper bound of the CI ----------------------'

As described above, a change is considered significant if the CI is entirely outside the configured SIGNIFICANT_IMPACT_THRESHOLD (or the deprecated UNCONFIDENCE_THRESHOLD).

For instance, for an execution time metric, this confidence interval indicates a significantly worse performance:

----------------------------------------|---------|---(---------^---------)---------->
                                       0%        1%  1.3%      2.2%      3.1%
                                                  |   |         |         |
       significant impact threshold --------------'   |         |         |
                      lower bound of CI --------------'         |         |
       sample mean (center of the CI) --------------------------'         |
                      upper bound of CI ----------------------------------'
