打造速度快、响应及时的应用
Get insights into how your app performs from your users’ point of view, with automatic and customized performance tracing.
使用跟踪记录，了解性能问题的相关情况
Using custom traces, you can understand the context in which performance issues take place and more easily address them. You can also make use of automated traces, like app startup time.
密切关注网络行为
Understand the network latencies affecting your users with automated monitoring of HTTP/S requests. You can track response times, success rates, payload sizes, and the time spent waiting for the payload versus downloading it.
找出问题根源
Break down both trace and network data into dimensions like app version, country, device, and OS level to get to the bottom of issues.
