feat(config): introduce the global DD_AGENTLESS_ENABLED flag

[bwoebi]

Centralizing any agentless configs in a single place, making DD_AGENTLESS_ENABLED the fallback for any more specific agentless settings.

Also integrates agentless RC in particular.

Benchmarks

Benchmark execution time: 2026-08-22 06:14:19

Comparing candidate commit 6cd77ff in PR branch bob/agentless-setting with baseline commit 3bb9ecd in branch main.

📊 Benchmarking dashboard

Found 0 performance improvements and 6 performance regressions! Performance is the same for 616 metrics, 10 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 ----------------------------------'

The global flag can send traces to the Datadog intake when the user sets a different OTLP trace endpoint. It can also select the wrong OTLP protocol, remove intake authentication with custom headers, and use the wrong trace-stats default.
