Buildkite's latest release of its agent version 3.27.0 introduces a new integration with Datadog APM, contributed by community members goodspark and samschlegel, which enhances insight into CI/CD processes by optimizing compute efficiency, identifying common errors, and exploring slower build steps. Initially challenged by the lack of APM usage until its adoption in 2020, Buildkite confirmed the feature's utility through testing on its Elastic CI Stack for AWS fleets, resulting in a stable release. The Datadog APM integration allows users to monitor CI infrastructure with data on requests, errors, and latency, enabling optimizations such as reducing rspec test flakiness, thus improving CI infrastructure efficiency. Future plans involve transitioning the APM implementation from OpenTracing to OpenTelemetry, reflecting broader support, and continuing to enhance Buildkite's monitoring capabilities with further community contributions welcomed.
