Issue 1 - Duplicate lambda root spans

The instrumentation produces 2 lambda root spans upon each invocation of the function. This is a known issue in OTel: open-telemetry/opentelemetry-java-instrumentation#7808

Fix

  • Otel has fixed it in this PR but the change wasn't ported to the 1.x versions. So I took the diff from the upstream commit and made it into a patch that we apply when building the ADOT Java Lambda Layer for v1.33.x.

Issue 2 - Unsampled spans do not produce Application Signals metrics

On lambda environment, we export 100% of the spans to X-Ray to ensure we are able to provide 100% Application Signals metrics. However, currently only the sampled spans show up on the "Services" page and the unsampled spans do not.

Fix

  • Upon comparing the sampled vs unsampled spans, I noticed that the unsampled spans are missing the attributes like aws.local.service and aws.local.operation which are required to generate Application Signals metrics.
  • The fix is to wrap the OtlpUdpSpanExporter instance for unsampled spans with the AwsMetricAttributesSpanExporter so that the exported spans have the desired attributes.

Testing

  • After creating a layer with the fix, I set the OTEL_TRACES_SAMPLER to always_off. Then I invoked the function once.
  • The metrics appeared on the Application Signals console.
  • See the following screenshots

[Bugfix] Duplicate lambda spans in Java 11 (#1011)
329ecd4 
In the [previous
bugfix](#1000),
we missed porting this change from OTel specifically for Java 8 and 11
runtimes.

open-telemetry/opentelemetry-java-instrumentation#10942

**Testing:** Created an ADOT lambda layer with the change and verified
that the duplicate lambda spans do not appear for Java 11, 17, and 21.

[Lambda Java v2.11.x] Merge All Code Changes from v1.33.x Branch into v2.11.x (aws-observability#1114)

This change merges all private Lambda Java updates from the v1.33 branch
into the v2.11.x branch. I performed a 'git rebase v2.11' on the v1.33
branch, reviewed all changes, and completed the build and testing
process. The resulting Lambda layer generated trace data identical to
the version built directly from the v2.11.x branch (excluding this PR).
