Shadow of #5587 (#5587), opened automatically by Gardener so trusted CI can run against the fork's changes from within this repository.

Opened on behalf of @darccio.

Using DD_DOGSTATSD_URL=udp://host:port reached the statsd client verbatim and failed to parse with "too many colons in  address." This form is already established and documented by datadog-go. These changes match the behavior along with default hostname and port.

parseDogstatsdAddr only recognized unix:// and otherwise used the value
verbatim as the host, so DD_DOGSTATSD_URL=udp://host:port reached the
statsd client as "udp://host:port" and failed with "too many colons in
address". The tracer then ran without a statsd client, dropping its
runtime, health and contrib metrics.

udp:// is the form datadog-go documents for DD_DOGSTATSD_URL. Parse it
to host:port, defaulting the port to 8125 as datadog-go does. The same
parser backs WithDogstatsdAddr, so that option accepts udp:// too.

Also fix comments that called the scheme-less host:port form TCP;
datadog-go sends it over UDP.

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

Unstable benchmarks

These benchmarks have a confidence interval too wide to call a change; treat them as noise rather than signal.

  • unstable execution_time [-1.407ns; +1.785ns] or [-4.788%; +6.075%]

Known flaky benchmarks

These benchmarks are marked as flaky and will not trigger a failure. Modify FLAKY_BENCHMARKS_REGEX to control which benchmarks are marked as flaky.

Known flaky benchmarks without significant changes:
