问题的提出
公司有一个用户行为分析系统，可以记录用户在使用公司产品过程中的一系列操作轨迹，便于分析产品使用情况以便优化产品 UI 界面布局。这套系统有点类似于 Google Analyse（GA），所不同的是，为了让用户把产品用起来，公司会将用户行为与优惠活动联系起来，例如购买产品后一段时间内如果使用时长达到一定标准，就能从销售那里领取小礼品，初衷是为了让用户把产品用起来。可是这个活动一经推出，我这边电话就被打爆了，因为经常有用户感觉自己在用产品了，但是销售给他反馈的时长信息却没有增长。于是实施同事会要求我们去排查问题，可能很多情况下，就是用户没联网、或者防火墙设置的太严格了导致数据上不来、甚至是后台服务挂了导致数据没及时分析……其实 90% 以上的问题和客户端没关系，而是后台在某个环节丢失了数据，但是作为查问题的第一个环节，客户端开发往往会被顶到前线充当 call center 的角色，浪费大量个人时间不说，效率也是极低的。于是自然而然就会想到，能不能做一个分析工具，自动从日志里提出关键数据，做成直观的图表展示给实施人员，可以一眼就能定位出是客户端还是后台的问题，从而达成初步排 (甩) 查 (锅) 的目的？
问题的解决
要能从日志中提取出行为数据（专业术语称为埋点）并根据时间顺序绘制一幅活跃图的根基，是日志中要有相应的记录，巧的是，之前为了排查问题，已经在日志中输出了大量这样的信息：

可以看到关键日志的格式类似如下：
2020-08-31 10:17:48.140 2248 3360 [1] add action GDraw.调整文本 (1)
分别对应的字段是：
日期 时间(带毫秒) 进程号 线程号 [日志级别] add action 产品标识.操作 (入队结果)
所以我们大体可以分两步完成这个工作，一是提取关键日志，二是根据数据绘制活跃图。
提取日志数据
因为日志里夹杂了太多不相关的数据，我们需要先进行一波清洗，这个是 sed 的拿手好戏：
$ sed -n '/add action .*..*/p' gux_log.1.txt 2020-08-31 10:15:44.697 2248 3360 [1] add action GDraw.启动 (0) 2020-08-31 10:15:44.837 2248 3360 [1] add action GDraw.新建文件 (1) 2020-08-31 10:15:48.254 2248 3360 [1] add action GDraw.添加弧 (1) 2020-08-31 10:15:53.683 2248 3360 [1] add action GDraw.添加长方形 (1) 2020-08-31 10:15:57.349 2248 3360 [1] add action GDraw.添加圆 (1) 2020-08-31 10:16:03.854 2248 3360 [1] add action GDraw.添加圆 (1) 2020-08-31 10:16:10.843 2248 3360 [1] add action GDraw.添加椭圆 (1) 2020-08-31 10:16:14.290 2248 3360 [1] add action GDraw.添加多边形 (1) 2020-08-31 10:16:19.251 2248 3360 [1] add action GDraw.添加文本 (1) 2020-08-31 10:16:24.274 2248 3360 [1] add action GDraw.添加直线 (1) 2020-08-31 10:16:37.363 2248 3360 [1] add action GDraw.设置文本 (1) 2020-08-31 10:16:37.378 2248 3360 [1] add action GDraw.设置文本 (1) 2020-08-31 10:16:37.378 2248 3360 [1] add action GDraw.设置文本 (1) 2020-08-31 10:16:41.325 2248 3360 [1] add action GDraw.置底椭圆 (1) 2020-08-31 10:16:41.325 2248 3360 [1] add action GDraw.置底文本 (1) 2020-08-31 10:16:41.325 2248 3360 [1] add action GDraw.置底直线 (1) 2020-08-31 10:16:45.943 2248 3360 [1] add action GDraw.移动椭圆 (1) 2020-08-31 10:16:49.390 2248 3360 [1] add action GDraw.删除圆 (1) 2020-08-31 10:16:52.963 2248 3360 [1] add action GDraw.删除圆 (1) 2020-08-31 10:16:55.162 2248 3360 [1] add action GDraw.粘贴圆 (1) 2020-08-31 10:16:59.873 2248 3360 [1] add action GDraw.调整圆 (1) 2020-08-31 10:17:04.475 2248 3360 [1] add action GDraw.调整长方形 (1) 2020-08-31 10:17:07.798 2248 3360 [1] add action GDraw.调整多边形 (1) 2020-08-31 10:17:11.511 2248 3360 [1] add action GDraw.调整弧 (1) 2020-08-31 10:17:16.019 2248 3360 [1] add action GDraw.调整直线 (1) 2020-08-31 10:17:44.973 2248 3360 [1] add action GDraw.设置文本 (1) 2020-08-31 10:17:44.973 2248 3360 [1] add action GDraw.设置文本 (1) 2020-08-31 10:17:44.973 2248 3360 [1] add action GDraw.设置文本 (1) 2020-08-31 10:17:48.140 2248 3360 [1] add action GDraw.调整文本 (1) 2020-08-31 10:17:55.924 2248 3360 [1] add action GDraw.删除文本 (1) 2020-08-31 10:18:07.188 2248 3360 [1] add action GDraw.保存文件 (1) 2020-08-31 10:18:08.326 2248 3360 [1] add action GDraw.关闭文件 (1) 2020-08-31 10:18:08.576 2248 3360 [1] add action GDraw.退出 (1) 2020-08-31 10:20:14.546 2248 3360 [1] add action GDraw.timer_duration (0)
接下来要从清洗后的日志中提取日期、时间、进程号、产品标识、操作 5 个字段到该产品标识对应的文件中，这个是 awk 的分内活儿：
sed -n '/add action *.*/p' gux_log.1.txt | awk -F "[. ]+" '{ print $1,$2,$4,$9,$10 >> "plot/"$9".txt"; a[$9]++ } END { for (i in a) print i " : " a[i] }'
因为产品标识与操作是用 '.' 号分隔的，所以要在分隔符中加入点号 (默认为空格)，不过这样一来，就会把时间和毫秒也分成两个字段，所以我们要提取的字段下标（从 1 开始）就分别变成了日期(1)、时间(2)、进程号(4)、产品标识(9)、操作(10)。提取到的数据行会写入对应的产品标识命名的文件中 ("plot/GDraw.txt")，注意这里的 $9 不能包含在引号中，否则不起作用 (awk 语法补习一下)。并递增对应的产品标识埋点数据，最后将所有的产品统计信息打印出来：
GDraw : 34
同时在 plot 子目录下可以找到以 GDraw 命名的数据文件 (GDraw.txt)：
$ cat plot/GDraw.txt 2020-08-31 10:15:44 2248 GDraw 启动 2020-08-31 10:15:44 2248 GDraw 新建文件 2020-08-31 10:15:48 2248 GDraw 添加弧 2020-08-31 10:15:53 2248 GDraw 添加长方形 2020-08-31 10:15:57 2248 GDraw 添加圆 2020-08-31 10:16:03 2248 GDraw 添加圆 2020-08-31 10:16:10 2248 GDraw 添加椭圆 2020-08-31 10:16:14 2248 GDraw 添加多边形 2020-08-31 10:16:19 2248 GDraw 添加文本 2020-08-31 10:16:24 2248 GDraw 添加直线 2020-08-31 10:16:37 2248 GDraw 设置文本 2020-08-31 10:16:37 2248 GDraw 设置文本 2020-08-31 10:16:37 2248 GDraw 设置文本 2020-08-31 10:16:41 2248 GDraw 置底椭圆 2020-08-31 10:16:41 2248 GDraw 置底文本 2020-08-31 10:16:41 2248 GDraw 置底直线 2020-08-31 10:16:45 2248 GDraw 移动椭圆 2020-08-31 10:16:49 2248 GDraw 删除圆 2020-08-31 10:16:52 2248 GDraw 删除圆 2020-08-31 10:16:55 2248 GDraw 粘贴圆 2020-08-31 10:16:59 2248 GDraw 调整圆 2020-08-31 10:17:04 2248 GDraw 调整长方形 2020-08-31 10:17:07 2248 GDraw 调整多边形 2020-08-31 10:17:11 2248 GDraw 调整弧 2020-08-31 10:17:16 2248 GDraw 调整直线 2020-08-31 10:17:44 2248 GDraw 设置文本 2020-08-31 10:17:44 2248 GDraw 设置文本 2020-08-31 10:17:44 2248 GDraw 设置文本 2020-08-31 10:17:48 2248 GDraw 调整文本 2020-08-31 10:17:55 2248 GDraw 删除文本 2020-08-31 10:18:07 2248 GDraw 保存文件 2020-08-31 10:18:08 2248 GDraw 关闭文件 2020-08-31 10:18:08 2248 GDraw 退出 2020-08-31 10:20:14 2248 GDraw timer_duration
过滤掉了不相关的内容，显得清爽多了。这还仅仅是一个产品的埋点数据，如果有多个产品的话，就可以看到更有趣的一些输出，例如：
GDraw : 93 GTJ2021 : 17 GCCP5 : 70 GCCP6 : 154
每个产品会单独统计埋点数，同时在 plot 目录下生成每个产品的数据文件。
不同的日志格式
以为上面就解决了日志清洗的所有问题？No！因为代码的不断的调整，曾经出现过三种格式的日志，下面分别列举：
v2 [1] 2019-09-19 00:39:24 10772 5992 add action GDQ2018.合并 (1) v3 2020-06-11 13:38:34.666 17272 17712 [1] add action GCCP5.timer_duration (1) v3.1 2020-06-11 13:38:34.666 17272 17712 gmtsvc [1] add action GCCP5.timer_duration (1)
具体说我们刚才处理的日志其实是 v3 版本的，另外还有 v2 版本，这个是最老的日志，与 v3 的区别是日志级别是放在最前面的，时间没有毫秒值；还有 v3.1 版本，这个是最新的日志，与 v3 的区别是日志级别之前加了一个模块名称字段。这些字段顺序的调整与额外字段的增加，会导致我们读取时需要选择的字段下标不同，例如下面的 awk 语句分别对应上面三种版本的日志：
# v2 $ sed -n '/add action *.*/p' gux_log.1.txt | awk -F "[. ]+" '{ print $2,$3,$4,$8,$9 >> "plot/"$8".txt"; a[$8]++ } END { for (i in a) print i " : " a[i] }' # v3 $ sed -n '/add action *.*/p' gux_log.1.txt | awk -F "[. ]+" '{ print $1,$2,$4,$9,$10 >> "plot/"$9".txt"; a[$9]++ } END { for (i in a) print i " : " a[i] }' # v3.1 $ sed -n '/add action *.*/p' gux_log.1.txt | awk -F "[. ]+" '{ print $1,$2,$4,$10,$11 >> "plot/"$10".txt"; a[$10]++ } END { for (i in a) print i " : " a[i] }'
它们的输出都是一样的。好在 awk 支持条件判断，我们完全可以在一条语句里进行不同版本的日志处理：
$ sed -n '/add action *.*/p' gux_log.1.txt | awk -F "[. ]+" '{ if ( $1 ~ /[[0-9]]/ ) { print $2,$3,$4,$8,$9 >> "plot/"$8".txt"; a[$8]++ } else if ( $9 == "action" ) { print $1,$2,$4,$10,$11 >> "plot/"$10".txt"; a[$10]++ } else { print $1,$2,$4,$9,$10 >> "plot/"$9".txt"; a[$9]++ } } END { for (i in a) print i " : " a[i] }'
被压扁在一行了，单独提取 awk 的部分列在下面看着更清晰一些：
1 { 2 if ( $1 ~ /[[0-9]]/ ) { print $2,$3,$4,$8,$9 >> "plot/"$8".txt"; a[$8]++ } 3 else if ( $9 == "action" ) { print $1,$2,$4,$10,$11 >> "plot/"$10".txt"; a[$10]++ } 4 else { print $1,$2,$4,$9,$10 >> "plot/"$9".txt"; a[$9]++ } 5 } 6 7 END { for (i in a) print i " : " a[i] }
新增的部分主要在条件判断的地方，如果第 1 个字段符合正则式则走第一个条件的语句，这条正则式是说“方括号括起来的数字”，就是[1]、[2]、[3]……啦，这是用来匹配 v2 日志的；如果第 9 个字段为 “action"，则走第二个条件的语句，这是用来匹配 v3.1 日志的；剩下的 else 就当然是用来区别 v3 日志的啦。这样一来即使一个文件中有不同版本的日志，也能轻松处理。
绘制埋点活跃图
其实经过日志清洗后，得到的各产品”纯纯“的数据，就已经可以交差了，因为没有什么是比数据更准确的啦。但是考虑到我面对的人可能是连 Windows 服务在哪里控制都找不到的人，我决定更进一步，通过各产品的数据绘制一幅直观的埋点图，来给用户一个傻瓜式的体验（谁叫我懒），先上效果图：
这个图的横轴表示时间，纵轴表示会话，可以认为一个产品启动到关闭整个过程为一次会话 (通过进程 ID 值代表)。如果对应的时间段有数据点的话，就表示该产品在那个时间活跃过。以上图为例，如果我们想看 GCCP5 这个产品在哪天活跃过，就可以在图中查找图例对应颜色的点，可以看到，大部分集中在 6.10-6.13 这个区间，其它时间段比较少。又例如，我想查看 8.21-8.27 之间有无产品活跃，从图中看到这段时间区间是一片空白，所以可以确定用户在这个时间段没有使用公司的产品。那么这张图是怎么生成的呢，这就需要用到 gnuplot 了，其实我之前写过的文章有对这个工具使用方法的详细说明，感兴趣的可以参考这篇《查看博客园积分与排名趋势图的工具》。下面直接上代码，首先是 shell 脚本部分 (guxplot.sh)：
1 #! /bin/bash 2 arg="logs='" 3 logs=$(cd plot; find . -type f -name "*.txt") 4 if [ -z "$logs" ]; then 5 echo "no data stripped, exit plotting!" 6 exit 7 fi 8 9 for log in $logs 10 do 11 # skip ./ 12 tmp=${log:2} 13 # emit .txt 14 tmp=${tmp%.*} 15 echo $tmp 16 arg="$arg$tmp " 17 done 18 19 arg="$arg'" 20 gnuplot -e "logpath='$1'" -e "$arg" ./gux.plt 21 # mspaint only know other than / 22 #mspaint "plot/gux.png" 23 mspaint "plot\gux.png" &
这个脚本的核心是遍历之前生成数据的 plot 子目录，将其中 .txt 结尾的数据文件取出，依次放入 arg 参数中，将其作为一个参数 (logs) 传递给 gnuplot 脚本 (gux.plt) 去执行。另外它还有一个输入参数 ($1)，也作为一个参数 (logpath) 传递给了 gnuplot 脚本。下面来看绘制代码 (gux.plt)：
1 #! /usr/bin/gnuplot 2 set terminal png size 1080,720 3 set title logpath 4 set output "plot/gux.png" 5 set grid 6 7 set xdata time 8 set timefmt "%Y-%m-%d %H:%M:%S" 9 set format x "%m/%d" 10 set xtic rotate by 315 # 270 + 45 11 set xtics 86400*3 # three day a big tic 12 set mxtics 3 # every day a small tic 13 14 # plot in double Y axises 15 set xlabel "day(s)" 16 set ylabel "session(pid)" 17 18 #plot "log.txt" using 2:4 with points pt 1 title "score" 19 plot for [log in logs] "plot/".log.".txt" using 1:3 w points pt 5 title log 20 21 quit
简单解读一下：
- 进行一些基本设置 (line 2-6)；
- 设置横坐标 (line 7-12)，包括设置时间轴、时间格式、横坐标刻度等等；
- 设置坐标名称 (line 15,16)；
- 最后一条语句完成所有绘制 (line 19)。
重点说明一下最后一条，正常的数据绘制是如 line 18 所示，有输入数据 (log.txt)、有使用的数据列 (using 2:4)、有展现形式 (with points pt 1)、有图例名称 (score)。它和 19 行的区别在于，后者是一条循环语句，它遍历 logs 参数中的所有值并将当前值存放在 log 变量中 (其实就是产品标识啦)，后面它用这个变量拼接出了输入的数据来源 (例如 plot/GDraw.txt，注意 gnuplot 是使用 '.' 来连接字符串与变量的)；最后还用这个变量命名了图例的名称 (title log)；其它和 18 行没有什么区别。如果对上一个脚本 guxplot.sh 还有印象的话，它一共传递给这个脚本两个参数：logs 和 logpath，刚刚说明的是前者，后者是用来设置标题的，这样就能清楚得知数据来源。
把一切串起来
关键脚本搞清楚之后，我们就可以做总成了，下面是驱动”一切“的那个脚本 (guxstrip.sh) ：
1 #! /bin/bash 2 use_local=1 3 gdpdir=$(pwd) 4 logs=$(find . -type f -name "gux_log.*.txt") 5 if [ -z "$logs" ]; then 6 use_local=0 7 echo "no log found under current directory, try system..." 8 gdpdir="/cygdrive/c/ProgramData/Glodon/GUX/3.0" 9 iswinxp=$(Wmic OS Get Caption | grep "XP") 10 if [ ! -z "$iswinxp" ]; then 11 echo "winxp detected!" 12 gdpdir="/cygdrive/c/Documents and Settings/All Users/Application Data/Glodon/GUX/3.0" 13 fi 14 15 logs=$(find "$gdpdir" -type f -name "gux_log.*.txt") 16 if [ -z "$logs" ]; then 17 echo "no log found, nothing to do, quit" 18 exit; 19 fi 20 fi 21 22 n=1 23 sel=-1 24 echo "0: all" 25 for log in $logs 26 do 27 echo "$n: $log $(stat -c '%s' $log) bytes" 28 n=$(($n+1)) 29 done 30 31 until [ $sel -ge 0 ] && [ $sel -lt $n ] 32 do 33 echo -n "which log do you want to strip: (0) " 34 read sel 35 if [ -z "$sel" ]; then 36 sel=0 37 fi 38 done 39 40 rm -rf plot 41 mkdir plot 42 43 n=0 44 for log in $logs 45 do 46 if (( $sel == 0 )) || (( $n == $sel - 1 )); then 47 echo "handle log: $log" 48 echo "handle log: $log" >> "plot/plot.log" 49 sed -n '/add action .*..*/p' "$log" > "plot/gux.data" 50 if [ ! -s "plot/gux.data" ]; then 51 echo "no valid data in that file, skip" 52 n=$(($n+1)) 53 continue; 54 fi 55 # 2.0 log format 56 # 57 # [1] 2019-09-19 00:39:24 10772 5992 add action GDQ2018.合并 (1) 58 # 59 # 3.0 log format v1 60 # 61 # 2020-06-11 13:38:34.666 17272 17712 [1] add action GCCP5.timer_duration : xxx 62 # 63 # 3.0 log format v2 64 # 65 # 2020-06-11 13:38:34.666 17272 17712 gmtsvc [1] add action GCCP5.timer_duration : xxx 66 # 67 # to adapt all of them 68 awk -F "[. ]+" '{ if ( $1 ~ /[[0-9]]/ ) { print $2,$3,$4,$8,$9 >> "plot/"$8".txt"; a[$8]++ } else if ( $9 == "action" ) { print $1,$2,$4,$10,$11 >> "plot/"$10".txt"; a[$10]++ } else { print $1,$2,$4,$9,$10 >> "plot/"$9".txt"; a[$9]++ } } END { for (i in a) print i " : " a[i] }' "plot/gux.data" >> "plot/plot.log" 69 70 # prepare the remote file for later compress 71 if [ "$use_local" -eq 0 ]; then 72 cp "$log" "./plot/${log##*/}.log" 73 fi 74 fi 75 n=$(($n+1)) 76 done 77 78 logs=$(find plot -type f -name "*.txt") 79 if [ -z "$logs" ]; then 80 echo "no data stripped, exit plotting!" 81 exit 82 fi 83 84 echo -e "nstart ploting" 85 bash.exe guxplot.sh "$gdpdir" # 2>>error.txt 86 87 # last pack them up! 88 echo -e "nstart packing" 89 rm plot.tar.gz 90 rm "plot/gux.data" 91 92 # tar can NOT find gzip in our situation 93 # so use them separately 94 #tar cvzf plot.tar.gz plot 95 tar cvf plot.tar plot 96 gzip plot.tar 97 98 echo "work done!"
简单解读一下：
- 首先判断输入日志来源 (line 2-20)，如果在系统目录下找不到日志，就在本目录查找，这样便于直接分析获取到的日志，而不是去用户机器上装一个工具。如果都找不到，就没得可分析，直接退出。这里系统的话由于WinXP 和 Win7+ 存放的目录不一样，所以要区分一下，注意这个脚本虽然是 shell 脚本，但是是运行在 Windows 系统上的，所以一些 windows 的工具和命令也是可以直接调用的 (Wmic)；
- 接着将查找到符合条件的日志名称 一 一 列出，供用户选择，用户可以直接回车 (或输入 0) 表示处理所有日志输入，也可以输入一个序号，表示只处理序号对应的日志。当用户只关心最近的日志数据的话，可以使用后面这个功能来缩小处理的日志时间范围，使生成的活跃图更精确一些；
- 分别处理各个日志 (line 43-76)，用到了我们前面介绍的 sed 与 awk，注意添加数据时使用的是追加 (>>)，这样可以避免覆盖前面生成的数据。同时如果日志不在当前目录下面，会自动将日志也复制到打包目录，方便万一有问题时继续进行分析；
- 如果没有任何数据文件生成 (line 78-82)，表示日志中没有有效的数据，没得分析，退出；
- 绘制活跃图 (line 84,85)；
- 将所有的数据和图表压缩成一个 tar 包 (line 87-96)，方便后续提交。这时里本来想用 'tar cvzf‘ 一步生成，结果 tar 老是报 gzip 找不到，虽然我已经提供了这个 exe，后来拆分成两步 (tar + gzip) 就好了，可能是 tar 有它自己的查找方式，在移植到 windows 环境后被破坏掉了。
下面是这个脚本的运行截图：
运行结束后会自动弹出埋点活跃图。
结语
其实前面稍微提到了一点，就是我是在 Windows 环境下运行 shell 脚本的，使用的是 msys2，一种类似 cygwin 的东东，我前几篇文章都有提到过。最终这个日志清洗工具做好后，我只需要把我用到的 msys2 命令提取出来，就可以在新的机器上运行了，既不用安装，也不用注册，完全是个”绿色“版本啊。下面一张工具内容的截图为证：
其中 exe 除了 bash.exe 外，均为脚本中用到的命令；dll 基本是各个 exe 依赖的文件，这个是通过试运行报错后一个一个从 msys2 系统扒过来的；bat、sh 与 plt 基本就是我们的脚本文件啦。整个工具占用空间 23.3 MB，压缩后仅仅 10 MB 多一点，非常便于给用户交付，我想这也是 msys2 系统相比于各种脚本语言最大的优势 —— 不需要安装庞大的语言虚拟机或运行时库，用到什么再添什么，比较小巧灵活，适合我这种简单的任务。
