调用DescribeCacheAnalysisReport查看Redis实例在指定日期中的缓存分析报告。
- Redis实例的引擎版本为4.0或以上；
- Redis实例的小版本为最新，小版本是否需要升级请参见如何确认Redis实例的小版本是不是最新版。
云数据库Redis版的缓存分析功能在每日全量备份数据时对缓存结构进行分析，找出每个数据节点中占用空间最大的80个Key，保存分析结果供您查看。
除了每天的自动分析，您还可以发起实时的缓存分析任务，可供选择的发起方法如下：
- 调用CreateCacheAnalysisTask创建缓存分析任务。
- 在Redis控制台发起实时分析，操作步骤请参见缓存分析。
说明
- 云数据库Redis版只会保存每天最新的一条分析结果，如您先通过手动操作进行了分析，当日稍晚时间系统进行了自动分析，系统会保留系统自动分析的结果，删除之前手动发起分析任务获得的结果。
- 系统自动进行缓存分析的时间由数据全量备份的时间决定，您可以在控制台的备份与恢复页修改该时间。
