Bowen Chen explains how GitHub Actions provides tooling to automate and manage custom CI/CD workflows from your repositories, allowing for high velocity build, test, and delivery of application code. Datadog CI Visibility offers end-to-end visibility into GitHub Actions pipelines, helping maintain their health and performance through metrics, distributed traces, and job logs. Integrating GitHub Actions with CI Visibility allows users to investigate failing pipelines and performance bottlenecks, track down suspect commits, view correlated log data, analyze historical trends in build duration, and remediate issues to focus on developing new features. The integration provides a more granular view into pipeline executions, enabling teams to quickly identify and fix problems, ultimately improving the overall delivery process.
