 - `cop_task`：包含 cop task 的相关信息，如：
     - `num`：cop task 的数量
     - `max`,`min`,`avg`,`p95`：所有 cop task 中执行时间的最大值，最小值，平均值和 P95 值。
     - `max_proc_keys`, `p95_proc_keys`：所有 cop task 中 tikv 扫描 kv 数据的最大值，P95 值，如果 max 和 p95 的值差距很大，说明数据分布不太均匀。
-    - `rpc_num`, `rpc_time`：向 TiKV 发送 `Cop` 类型的 RPC 请求总数量和总时间。
     - `copr_cache_hit_ratio`：cop task 请求的 Coprocessor Cache 缓存命中率。[Coprocessor Cache 配置](/tidb-configuration-file.md)。
+- `rpc_info`：按照向 TiKV 发送 RPC 请求的类型统计总数量和总时间。
 - `backoff`：包含不同类型的 backoff 以及等待总耗时。
