[Tracer] (Event Grid 5/5) Enable integration and add support metadata

[pablomartinezbernardo]

Summary of changes

Enable Azure Event Grid tracing by default and add its support metadata.

Reason for change

Activate the integration introduced by the preceding PRs in this Graphite stack.

Implementation details

• Enable outbound SDK and Azure Functions Event Grid tracing by default.
• Register supported versions for Azure.Messaging.EventGrid and Azure.Messaging.EventGrid.Namespaces.
• Document inbound and outbound spans in the v0 and v1 span attribute schemas.

Test coverage

Existing Event Grid SDK, Namespaces, and Azure Functions integration tests now validate the default-enabled behavior without an explicit opt-in setting.

Other details

This PR is the final activation step in the Azure Event Grid Graphite stack.

Benchmarks

Benchmark execution time: 2026-10-02 13:30:34

Comparing candidate commit 7f7cac6 in PR branch pmartinez/event-grid-activation with baseline commit 619db52 in branch master.

📊 Benchmarking dashboard

Found 2 performance improvements and 12 performance regressions! Performance is the same for 58 metrics, 0 unstable metrics, 75 known flaky benchmarks, 51 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 ----------------------------------'
