您好我在 nodejs 中使用 redis 并尝试使用 jmeter 执行redis命令。
cpu使用率超过不超过5％，我试图增加负载，然后CPU使用率不超过5％。 当我尝试使用默认基准测试时，cpu使用率达到50％。
能否请你帮我制作redis最大cpu利用率
这是我的jmx文件
这是我的nodejs程序 var express = require（'express'）; var app = express（）;
|-- id: string (nullable = true)
|-- sentences: array (nullable = true)
| |-- element: struct (containsNull = true)
| | |-- sentence: string (nullable = true)
| | |-- attributes: array (nullable = true)
| | | |-- element: struct (containsNull = true)
| | | | |-- tokens: string (nullable = true)
| | | | |-- ner: string (nullable = true)
| | | | |-- pos: string (nullable = true)
答案 0 :(得分：2)
您可以使用默认的redis查询来了解CPU使用情况
尝试此查询以检查redis的cpu使用情况

从这里你可以获得精确的redis CPU使用率。即使你的CPU使用率较低，我们也可以从redis配置文件中修改它。
