Network issues are a common cause of performance problems in mobile applications, with more than half of application performance monitoring users primarily looking for answers to their network performance issues. To diagnose and fix these issues, it's essential to have deep insight into both server-side and client-side performance. Throughput is a critical metric to monitor, as it measures the number of requests processed within a given time interval. Payload size is also a significant factor, as large files can cause network congestion and slow down app performance. Additionally, tracking specific trace attributes, such as request parameters and response sizes, can help identify the root causes of network issues. It's also crucial to monitor both server-side and client-side requests for failures to get a comprehensive understanding of the issue. Automatic grouping logic in APM tools can also help simplify monitoring by grouping related network calls together. By using a specialized APM tool, such as Instabug, developers can quickly identify and resolve network performance issues, resulting in a better user experience.
