[I] 如何让brpc的brpcz只展示发生错误的请求？ (brpc)
YjyJeff opened a new issue, #3256:
URL: https://github.com/apache/brpc/issues/3256
线上服务，brpc请求很多。使用brpcz页面看到的都是ok，使用：
```
curl localhost:port/rpcz?error_code=1014
```
会显示 **Fail to find matched spans`**，但是确实是有这个错误的请求，请问如何解决？

brpc 的rpcz是采样收集的，不是所有的请求都会被保存

1. curl "localhost:port/rpcz?error_code=1014&max_scan=10000" 默认就扫描100条，可以通过设置参数扫描到1000条。
2. 如果上面还捞不到，那真的是非常低频了。可能需要新加feature，考虑采集的时候(/rpcz/enable) ，query parameter带上查询条件，只落特定条件的请求。比如error_doe=1014/min_latency=99/min_request_size=1024等。
