+# introduce
+In versions 2.1.4 and above of Doris, there will be a `profile_fe.sh` script in the fe deployment directory `${DORIS_FE_HOME}/bin`. This script can use the async-profiler tool to generate a flame graph of fe, which can be used to identify the bottleneck points of fe.
+
+:::note
+Note: The async profiler tool currently only supports Linux and MacOS systems, and does not currently support Windows systems
+:::
+
+The usage cases are as follows
+```shell
+$ # By default, monitor FE for 10 seconds to generate a flame graph
+$ ${DORIS_FE_HOME}/bin/profile_fe.sh
+
+$ # Set listening fe for 30 seconds to generate a flame graph
+$ PROFILE_SECONDS=30 ${DORIS_FE_HOME}/bin/profile_fe.sh
+```
+
+After running the above command, it will listen to fe for a period of time. During this period, we need to repeatedly send key queries to this FE so that the async-profiler can collect FE's key stack frame information.
+After collecting stack frame information, the script will generate an HTML flame graph file in the `${DORIS_FE_HOME}/log` directory. Generally, the bottleneck of fe will appear as a flat top (short and wide) in the flame graph. We can optimize the performance of the code corresponding to these stack frames.
+
+The following is an example of a flame graph
+
+
+# Using async-profiler in lower versions of fe
+In versions below 2.1.4, two files need to be manually downloaded
+1. Download [ap-loader-all-3.0-8.jar](https://repo1.maven.org/maven2/me/bechberger/ap-loader-all/3.0-8/ap-loader-all-3.0-8.jar) to the `${DORIS_FE_HOME}/lib`directory
+2. Download [profile_fe.sh](https://raw.githubusercontent.com/apache/doris/master/bin/profile_fe.sh) to the `${DORIS_FE_HOME}/bin`directory
+3. Just run `profile_fe.sh`

+# 介绍
+在doris 2.1.4及以上版本中，在fe部署目录`${DORIS_FE_HOME}/bin`中会存在一个`profile_fe.sh`脚本。该脚本可以利用async-profiler工具生成fe的火焰图，用来发现fe的瓶颈点。
+
+
+:::note
+注：async-profiler工具目前仅支持Linux和MacOS系统，暂未支持Windows系统
+:::
+
+使用案例如下
+```shell
+$ # 默认监听fe 10秒，生成火焰图
+$ ${DORIS_FE_HOME}/bin/profile_fe.sh
+
+$ # 设置监听fe 30秒，生成火焰图
+$ PROFILE_SECONDS=30 ${DORIS_FE_HOME}/bin/profile_fe.sh
+```
+
+在运行上面的命令后，将会监听fe一段时间。在这段时间内我们需要将关键的查询重复地发送给这个fe，使得async-profiler可以收集fe的关键栈帧信息。
+在收集栈帧信息完成后，脚本将会在`${DORIS_FE_HOME}/log`目录下生成一个html火焰图文件，通常来讲fe的瓶颈将会在火焰图中呈现为平顶山（又矮又宽）的形态，针对这些栈帧对应的代码，我们可以做性能的优化。
+
+如下是火焰图的示例
+
+
+# 在低版本fe中使用async-profiler
+在2.1.4以下的版本中，需要手动下载两个文件
+1. 将[ap-loader-all-3.0-8.jar](https://repo1.maven.org/maven2/me/bechberger/ap-loader-all/3.0-8/ap-loader-all-3.0-8.jar)下载至`${DORIS_FE_HOME}/lib`目录
+2. 将[profile_fe.sh](https://raw.githubusercontent.com/apache/doris/master/bin/profile_fe.sh)下载至`${DORIS_FE_HOME}/bin`目录
+3. 运行`profile_fe.sh`即可
