Dynatrace's engineering teams utilize Jenkins as their preferred build server to manage the complexities of a growing code base and diverse technology stacks while striving to optimize build times for their OneAgent across multiple platforms. The Engineering Productivity Team aims to reduce full build and test execution time from two hours to 45 minutes by leveraging automatically scaled Jenkins Nodes and Executors through Kubernetes clusters. They focus on effective capacity planning and configuration management to ensure efficient build processes, monitoring Jenkins with Dynatrace for comprehensive visibility into metrics like CPU usage, memory, and garbage collection. By addressing issues such as CPU spikes from merging test results and optimizing garbage collection settings, they enhance both system performance and user experience. Additionally, Dynatrace's Real User Monitoring (RUM) helps identify user interaction bottlenecks, allowing for further improvements in the Jenkins web interface. The team's strategic approach includes breaking down monolithic codebases, evaluating resource utilization, and potentially deploying multiple Jenkins servers to maintain efficiency and scalability.
