+## 概述
+
+高效好用的性能诊断工具对于数据库系统的调优至关重要，因为这关系到是否能快速定位到存在性能问题的业务 SQL，继而快速定位和解决性能瓶颈，保证数据库系统服务的
SLA。
+
+当前，Doris 系统默认将执行时间超过 5 秒的 SQL 认定为慢 SQL，此阈值可通过 `config.qe_slow_log_ms` 进行配置。目前
Doris 提供了以下三种诊断渠道，能够帮助快速定位存在性能问题的慢 SQL，分别如下：
+
+## Doris Manager 日志
+
+Doris Manager 的日志模块提供了慢 SQL 筛选功能。用户可以通过选择特定 FE 节点上的 `fe.audit.log` 来查看慢
SQL。只需在搜索框中输入“slow_query”，即可在页面上展示出当前系统的历史慢 SQL 信息，如下图所示：
