Bowen Chen discusses the challenges of monitoring complex CI/CD systems and shares strategies for troubleshooting issues and creating sustainable practices. Modern engineering teams rely on providers like GitHub Actions, GitLab, and Jenkins to build automated pipelines and testing tools. However, improving performance and troubleshooting failures can be challenging due to varying provider levels of visibility and terminology. Tools like CI Visibility help give teams shared context around CI/CD workflows. To effectively troubleshoot issues, platform engineers can use dashboards, alerting, and monitoring to track pipeline health over time and identify performance regressions. By implementing best practices such as establishing baselines for performance, identifying performance and reliability regressions, and gaining end-to-end visibility into the CI/CD system with tools like Datadog CI Visibility, teams can maintain the speed and reliability of their pipelines while scaling their teams and workflows.
