1. 接口描述
接口请求域名： dbbrain.tencentcloudapi.com 。
延迟分析-命令字分析-查询命令延迟趋势
默认接口请求频率限制：20次/秒。
推荐使用 API Explorer
点击调试
API Explorer 提供了在线调用、签名验证、SDK 代码生成和快速检索接口等能力。您可查看每次调用的请求内容和返回结果以及自动生成 SDK 调用示例。
2. 输入参数

| CommandList.N | 是 | Array of String | 需要分析的redis命令 示例值：["auth","eval","select","get","incrby","ping","set"] |
| Metric | 是 | String | 监控指标，以逗号分隔 示例值："qps,latency_p99,latency_avg,latency_max" |
| Period | 否 | Integer | 监控指标时间粒度，单位秒，若不提供则根据开始时间和结束时间取默认值 示例值：60 |
3. 输出参数
| 参数名称 | 类型 | 描述 |
|---|---|---|
| CmdPerfList | Array of CmdPerfInfo | redis命令延迟趋势 |
| RequestId | String | 唯一请求 ID，由服务端生成，每次请求都会返回（若请求因其他原因未能抵达服务端，则该次请求不会获得 RequestId）。定位问题时需要提供该次请求的 RequestId。 |
