Electronic Arts (EA) employs strategic monitoring of its app using Grafana dashboards to effectively track over 200 core metrics, a task that was previously overwhelming due to the app's monolithic design and the multitude of event emissions. EA Software Engineer Kenny Chen developed a "functional dashboard" system that allows developers to review these metrics quickly, significantly reducing the time needed for comprehensive monitoring. This system incorporates status history panels that use color-coding to visualize data, enabling the team to easily detect patterns and issues, such as regressions or external outages. By setting effective thresholds based on normal distribution principles, EA has improved its ability to identify and address critical errors related to code changes. The functional dashboards are dynamic, allowing developers to access specific data by using URLs with parameters, which facilitates more targeted troubleshooting. This approach has enhanced EA's monitoring capabilities, ensuring they have not missed any critical bugs and allowing for continuous improvement with automated updates and alerts.
