fix(trace-exporter): mark OTLP client-computed stats by bengl · Pull Request #2245 · DataDog/libdatadog

bengl · 2026-07-16T15:32:14Z

What does this PR do?

Marks OTLP trace exports as client-computed when tracer metadata already says stats were computed client-side.

This sets both:

the OTLP Resource attribute _dd.stats_computed=true
the direct Agent request header datadog-client-computed-stats: yes

when either metadata.client_computed_stats or libdatadog's native OTLP stats worker is enabled.

Motivation

dd-trace-js computes OTLP span metrics in JS and passes that state through set_client_computed_stats(). The OTLP trace exporter only looked at otlp_stats_enabled, so Resources sent by JS-backed stats did not carry _dd.stats_computed=true and system-tests rejected the payload.

Additional Notes

The native OTLP stats worker path remains unchanged because otlp_stats_enabled still sets the same Resource attribute and header.

How to test the change?

cargo test -p libdd-data-pipeline --test test_trace_exporter_otlp_export -- --nocapture

Result: 2 passed.

Comparing candidate commit f1d5c6f in PR branch bengl/otlp-client-computed-stats with baseline commit 3e3454a in branch main.

Found 2 performance improvements and 0 performance regressions! Performance is the same for 22 metrics, 0 unstable metrics.

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 ----------------------------------'

Out of curiosity, why can't the new test be implemented in term of json_body_includes? I'm not sure how it works exactly, but naively it looks like the previous payload could be extended for _dd.stats_computed

When tracers compute span metrics outside libdatadog, OTLP trace exports still need to mark the resource and direct Agent request so the Agent does not compute the same stats again. Use the tracer metadata flag in addition to libdatadog's native OTLP stats worker state.

Rebasing and merging in the absence of @bengl , this is blocking for a libdatadog-nodejs release.
