show命令
命令功能
展示已有的调优数据，提供整体和指定轮次数据的显示，并可以对参数重要性进行分析。
命令格式
show [-h] {round,top,importance} ...
参数说明
参数 |
参数选项 |
说明 |
|---|---|---|
-h/--help |
- |
获取show子命令的帮助信息。 |
round |
- |
展示指定对应轮次的信息。 |
top |
- |
展示以性能降序排列的前N个轮次的性能数据。 |
importance |
- |
全局参数重要性分析。 说明：
多轮次调优时若需了解哪些参数对性能提升有效果，可指定该参数。回显信息中“importance(%)”列的比值越高，该参数对于调优的相关性越高。 |
