Setting alerts for app performance is crucial for discovering new issues while minimizing manual monitoring time. Using Instabug's Application Performance Monitoring (APM), you can create alerts for various app performance situations, such as slow network requests, UI hangs, and cold/hot app launches. This helps engineering teams keep user satisfaction rates high by quickly identifying and fixing performance-related problems before they impact users. Alerts can be customized to track specific metrics, including response times, failure rates, and rate of change, allowing for more precise monitoring of app performance. By setting up alerts, you can reduce manual monitoring time, improve user retention, and revenue, while ensuring a robust app performance management strategy.
