[Tracer] (Event Grid 2/5) Register outbound SDK calltargets

[pablomartinezbernardo]

Summary of changes

Registers outbound CallTarget instrumentation for Azure.Messaging.EventGrid and Azure.Messaging.EventGrid.Namespaces.

Reason for change

Create producer spans and inject trace context where supported when applications publish Azure Event Grid events.

Implementation details

• Instruments synchronous and asynchronous publisher APIs for single and batched CloudEvent and EventGridEvent payloads.
• Regenerates CallTarget definitions and adds both SDK assemblies to trimming and Honeypot metadata.

Test coverage

End-to-end coverage is added in the follow-up outbound E2E PR in this stack.

Other details

This PR is part of a larger Graphite stack.

Benchmarks

Benchmark execution time: 2026-10-02 09:29:06

Comparing candidate commit 525e44f in PR branch pmartinez/event-grid-calltargets with baseline commit ec526ec in branch master.

📊 Benchmarking dashboard

Found 0 performance improvements and 10 performance regressions! Performance is the same for 62 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 ----------------------------------'

I wish we could unify all those instrumentation targets into something more centralized in the package, but there doesn't seem to be any good candidate

[zacharycmontoya]

For the best duck-typing performance, you should add a generic constraint so we do the ducktyping upfront and we don't have to do it later on in downstream method calls. And then in the EventGridCommon.CreateProducerSpan you can do the same, where you have the generic constraint TTarget : IEventGridPublisherClient

Suggested change

	internal static CallTargetState OnMethodBegin<TTarget, TEvents>(TTarget instance, ref TEvents events, CancellationToken cancellationToken)
	internal static CallTargetState OnMethodBegin<TTarget, TEvents>(TTarget instance, ref TEvents events, CancellationToken cancellationToken)
	where TTarget : IEventGridPublisherClient

[zacharycmontoya]

This feedback applies to all the calltarget OnMethodBegin's where you call EventGridCommon.CreateProducerSpan

[zacharycmontoya]

In a similar vein to my other duck-typing comment, I recommend doing the duck-type up front since we know what type it must be. Since you'll may want to handle a "null" singular event later, you'd then also make sure that ICloudEvent implements the IDuckType interface so you can check cloudEvent.Instance is not null as the "null check"

[zacharycmontoya]

LGTM with some small suggestions for eager duck-typing
