+通过`uprobe`或`kprobe`采样可获得函数执行的`trace`，但配置比较复杂，`trace`包含的信息很多，显示不直观。本工具旨在简易配置采样，以及分析所配置的函数的时延特征。
-主要应用场景：分析tcp/udp收发相关函数时延特征。
-
-## 原理
-基于u/kprobe 采样，可获得内核态和用户态函数的起止执行时间和结束执行时间的trace。
-可推导出:
-+ 函数间的调用关系
-+ 函数的执行时间
-+ 线程的调度特征
-
-## 主要功能
-
-+ 推导调用关系（乱序）
-+ 统计各函数调用栈时延信息
-+ 线程调度特征
-+ 记录系统信息
-
-## 使用限制
-+ 不支持递归函数分析
+主要应用场景：分析`tcp/udp`收发相关函数时延特征。

-
-+ /etc/da-tool.conf : 配置文件，主要配置需要抓取的函数
-+ /var/da-tool:
- + tmp
- + sample_output_* : 采样文件存放位置，可打包
- + analysis_input : 临时用于分析程序的依赖文件
- + analysis_output
- + debug : 可用于调试的参考日志
- + output : 时延结果信息
-
-## 使用方法
-### 命令格式
-时延分析工具通过`da-tool.sh`命令采集和分析函数时延，使用格式为
-
-**da-tool.sh** [-t <*probe time*>]
-
-|参数|是否必选|参数函数|
-|----|--------|-------|
-|-t |否| 采集函数 `trace` 的时长，单位秒，最大限制 100，默认10|
-
-### 自定义配置函数
-配置文件：`/etc/da-tool.conf`
-
-举例如下：
-```
-# /etc/da-tool.conf
-
-# kernel symbol config (ref: /proc/kallsyms)
-k,udp_recvmsg,udp_sendmsg,dev_queue_xmit,udp_send_skb,sock_recvmsg,__skb_recv_udp,udp_rcv
-
-# sched config
-s,sched_switch
-
-# user symbol config (format : u,path,bin_name,func1,func2,...,funcN)
-# u,/path/,bin_name,sendto
-u,/home/git_repo/nda-tool/nda-tool/test/net_demo2/,server_no_blk,recvfrom
-u,/home/git_repo/nda-tool/nda-tool/test/net_demo2/,client_to_noblk,sendto
-u,/home/git_repo/nda-tool/nda-tool/test/base_demo/,base_demo_cpp,_Z5func1v,_Z5func2v,_Z5func2i,_Z5func3v,_Z5func4v
-# end
-```
-
-+ k 开头为 kernel 符号，u 开头为用户态程序符号， s 开头为调度配置（目前仅支持`sched_switch`且必须配置）
-+ k 和 s 只能一行配置完
-+ u 可以多行配置, 格式：`[u,程序路径,二进制名称,追踪的函数]`
-+ 请确保函数存在，否则 `uprobe` 配置不成功，所配置的内核符号应在`/proc/kallsyms`能够查询到，所配置的用户态程序符号仅支持`C/C++`，且通过`objdump`应能够查询到
-+ 每行末尾不要有逗号
-
-
-注意，为了支持用户态不同二进制重名函数采集，配置`event`时，命名为`u0_func1`、`u1_func1`...，以上面配置为例，`_Z5func1v`为`u2__Z5func1v`。
-### 分析结果说明
-
-+ 终端输出结果：各函数调用栈的时延信息
-+ 文件夹输出结果 ： `/var/da-tool/analysis-output/ouput/`

-### 扩展功能
-`da-tool` 生成的结果信息可调用 火焰图生成工具，可视化分析结果，
-`./flamegraph.pl` 可在 `https://gitee.com/mirrors/FlameGraph` 中获取
-```shell
-# 全部信息
-cat /var/da-tool/analysis_output/output/func_delay_stack | grep -o '^[^,]*' | ./flamegraph.pl --countname "delay sum" > allpid.svg
-# 指定pid
-cat /var/da-tool/analysis_output/output/func_delay_stack | grep -o '^[^,]*' | grep -E 'pid1|pid2' | ./flamegraph.pl --countname "delay sum" > pid.svg
-```
-### 常见错误说明
-**配置了不存在的符号**
-```
-Failed to find symbol aaaa in kernel
- Error: Failed to add events.
-```
-**符号已存在,重复配置**
-```
-Error: event "aaaa" already exists.
- Hint: Remove existing event by 'perf probe -d'
- or force duplicates by 'perf probe -f'
- or set 'force=yes' in BPF source.
- Error: Failed to add events.
-```
+## 详情
-采集后会在`/var/da-tool/tmp`文件夹下生成一个`output_时间`格式的文件夹，包含此次采样的结果。
-采样脚本的采样日志在此路径下：
-```
-/var/da-tool/tmp/sample_output_时间/da-tool/sample.log

-### 注意事项
-+ 配置注意事项
- + 配置`/etc/da-tool.conf` 时，注意所配置符号一定存在
- + 某些函数名可能存在点(eg:A.B.C)，暂**不支持配置此类函数**，例如经过gcc优化选项`-fipa-sra`优化后，函数符号后缀会有`.rsra.num`。
- + 应用程序名也不要有点，建议函数和应用程序**不要包含特殊符号**
- + 某些函数可能短时间执行大量次数，此时`trace`很大，解析时间会很长，需要认为评估配置的函数运行情况，合理设置采样时间
- + 由于`trace`可能存在不完整的调用关系，很有可能在`trace`中存在的数据分析时舍弃，如果单次采样没有抓到需要的pid信息，建议多采样几次
- + 有时`trace`中会有数据丢失，结果可能异常，常见的异常原因为`trace`过大，内核刷新数据时不正常，比如会出现同一个函数只有返回时间没有进入时间的现象，建议减小采样时间。
- + 不支持递归函数
-+ 本工具单个CPU所使用的跟踪缓存`RingBuffer`大小为 `40960kb` ，当单核的`trace`大小接近此值时数据可能异常，进而导致分析结果错误。
-+ 确保`trace` 中有需要采集的函数的完整调用栈
