fix(dsm): Grab correct span in RabbitMQ/OTel for DSM checkpoints by robcarlan-datadog · Pull Request #8362 · DataDog/dd-trace-dotnet

robcarlan-datadog · 2026-03-24T17:14:51Z

Summary of changes

Fix DSM header injection for RabbitMQ / OTel. OTel emits a span which causes us to skip DSM checkpoint logic.

Reason for change

Customer issue

Implementation details

OnMethodEnd used tracer.ActiveScope?.Span to find the RabbitMQ producer span. When
DD_TRACE_OTEL_ENABLED=true, RabbitMQ.Client v7 emits its own OTel Activity which gets converted to a
scope with OpenTelemetryTags that sits on top of the dd-trace RabbitMQ scope (RabbitMQTags). The
pattern match activeSpan is not Span { Tags: RabbitMQTags } fails on the OTel span, so the method
bails out, skipping both DSM checkpoint and header injection.

OTel generated span from here
RabbitMQ span created from here

Comparing candidate commit 3c5e1d7 in PR branch rob.carlan/rabbitmq-v7-investigation with baseline commit 6aadb93 in branch master.

Found 6 performance improvements and 14 performance regressions! Performance is the same for 253 metrics, 15 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 ----------------------------------'

InternalActiveScope and ActiveScope both return the same scope stack — the OTel scope sits on top either way. The scope chain walk via scope.Parent is what actually fixes the issue. Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>

Comparison explanation

Execution-time benchmarks measure the whole time it takes to execute a program, and are intended to measure the one-off costs. Cases where the execution time results for the PR are worse than latest master results are highlighted in **red**. The following thresholds were used for comparing the execution times:

Welch test with statistical test for significance of 5%
Only results indicating a difference greater than 5% and 5 ms are considered.

Note that these results are based on a single point-in-time result for each branch. For full results, see the dashboard.

Graphs show the p99 interval based on the mean and StdDev of the test run, as well as the mean value of the run (shown as a diamond below the graph).
