Mysql 慢速查询日志是在日志文件中记录更快的查询

我在数据库服务器上设置了MySQL慢速查询日志，并将长查询时间设置为5
刚刚检查了日志及其只需毫秒的日志查询。有人知道为什么会这样吗？这是一些日志

I am using mysql sloq query log and set the following line in my.cnf file:
slow_query_log=1
long_query_time=5
log-output=FILE
log-queries-not-using-indexes

but my log file show like :

请帮助我哪里错了，我能为这个缓慢的查询日志做些什么

---

我想执行需要更多时间执行的查询。

设置

不使用索引的日志查询将向慢速日志添加任何不使用索引的查询

这应该被激活，因为它可以很容易地帮助您优化查询

如果您希望查询超过一定的秒数，则可以执行

从mysql.slow\u日志中选择*，其中query\u time>5

这将给出执行时间超过5秒的查询。
此查询放在哪里？我想检查哪个查询对于多用户登录执行缓慢。那么我如何检查..？在
WHERE
子句中使用
IN
。像
WHERE user_host IN（'root[root]@localhost[]”，“other usename etc'）
您想要什么extacly，因为您在问题中没有提到任何关于某些用户的信息。实际上，我想检查日志文件中哪个查询速度慢。当我不使用“日志查询不使用索引”时，我的日志不会被创建。但是当我在my.cnf文件中使用上面的语句“LogQueriesNotUsingIndexes”时，我的日志显示了上面的结果。我使用JMeter负载测试登录多用户。这就是我检查日志文件的原因
