+## 为什么抓取到的请求数量明显少于真实的请求数量？
+在大流量的情况下 kyanos 可能抓取不到完整的请求数据，检查 `/tmp` 目录下的 kyanos 日志，如果出现 `[dataReader] lost xx syscall data events` 的日志说明正是这种情况。

+如果想尽可能的抓取请求可以加上 `--trace-dev-event=false --trace-socket-data` 这个选项，加上该选项后不会抓取数据经过网卡和`socket buffer`的事件，将所有处理能力用于解析 syscall 数据上（目前通过 syscall 数据解析请求和响应）

 Make sure the protocol you want to monitor is not HTTP2, as kyanos does not
 currently support it.
 
+## Why is the number of captured requests significantly less than the actual number of requests?
+
+In high-traffic situations, kyanos may not be able to capture complete request data. Check the kyanos logs in the `/tmp` directory. If you see logs like `[dataReader] lost xx syscall data events`, it indicates this situation.
+
+If you want to capture as many requests as possible, you can add the `--trace-dev-event=false --trace-socket-data` option. With this option, events of data passing through the network card and `socket buffer` will not be captured, and all processing power will be used to parse syscall data (currently, requests and responses are parsed through syscall data).
