## Storage Write Stall

- Write & Delta Management Throughput：所有实例写入及数据整理的吞吐量。
- `throughput_write` 表示通过 Raft 进行数据同步的吞吐量。
- `throughput_delta-management` 表示数据整理的吞吐量。
- `total_write` 表示自上次启动以来的总写入字节数。
- `total_delta-management` 表示自上次启动以来数据整理的总字节数。
- Write Stall Duration：每个实例写入和移除 Region 数据产生的卡顿时长。
- Write Throughput By Instance：每个实例写入数据的吞吐量，包括 apply Raft 数据日志以及 Raft 快照的写入吞吐量。
- Write Command OPS By Instance：每个实例收到各种命令的总计数。
- `write block` 表示通过 Raft 同步数据日志。
- `delete_range` 表示从该实例中删除一些 Region 或移动一些 Region 到该实例中。
- `ingest` 表示这些 Region 的快照被应用到这个实例中。

## Raft

- Read Index OPS：每个 TiFlash 实例每秒触发 read_index 请求的次数，等于请求触发的 Region 总数。
