Thank you for your detailed reply and explanation. The daily callback power consumption data provided by MetricKit is very helpful for overall monitoring. However, when it comes to analyzing power consumption issues of online users, especially in identifying specific business scenarios and factors causing the problems, there are still some challenges. Therefore, we are considering the additional monitoring of power consumption factors such as CPU, GPU, network, location, and display, so that when there is fluctuation in the overall metrics and we receive user feedback, we can conduct attribution analysis. In this context, we have a few questions seeking your advice: Fine-grained Monitoring: We hope to monitor the resource usage of the application as well as each page to help quickly pinpoint issues. In terms of detailed monitoring of GPU and CPU usage, what do you think is the most reasonable way to implement this? Is polling to calculate averages a feasible method? Real-time and Accuracy: How can we ensure real-time and accurate resource usage monitoring while minimizing power consumption overhead? Thank you again for your previous guidance, and I hope to receive more advice from you.
