用 shell 腳本做日誌清洗
問題的提出
公司有一個用戶行為分析系統，可以記錄用戶在使用公司產品過程中的一系列操作軌跡，便於分析產品使用情況以便優化產品 UI 介面布局。這套系統有點類似於 Google Analyse（GA），所不同的是，為了讓用戶把產品用起來，公司會將用戶行為與優惠活動聯繫起來，例如購買產品後一段時間內如果使用時長達到一定標準，就能從銷售那裡領取小禮品，初衷是為了讓用戶把產品用起來。可是這個活動一經推出，我這邊電話就被打爆了，因為經常有用戶感覺自己在用產品了，但是銷售給他回饋的時長資訊卻沒有增長。於是實施同事會要求我們去排查問題，可能很多情況下，就是用戶沒聯網、或者防火牆設置的太嚴格了導致數據上不來、甚至是後台服務掛了導致數據沒及時分析……其實 90% 以上的問題和客戶端沒關係，而是後台在某個環節丟失了數據，但是作為查問題的第一個環節，客戶端開發往往會被頂到前線充當 call center 的角色，浪費大量個人時間不說，效率也是極低的。於是自然而然就會想到，能不能做一個分析工具，自動從日誌里提出關鍵數據，做成直觀的圖表展示給實施人員，可以一眼就能定位出是客戶端還是後台的問題，從而達成初步排 (甩) 查 (鍋) 的目的？
問題的解決
要能從日誌中提取出行為數據（專業術語稱為埋點）並根據時間順序繪製一幅活躍圖的根基，是日誌中要有相應的記錄，巧的是，之前為了排查問題，已經在日誌中輸出了大量這樣的資訊：

可以看到關鍵日誌的格式類似如下：
2020-08-31 10:17:48.140 2248 3360 [1] add action GDraw.調整文本 (1)
分別對應的欄位是：
日期 時間(帶毫秒) 進程號 執行緒號 [日誌級別] add action 產品標識.操作 (入隊結果)
所以我們大體可以分兩步完成這個工作，一是提取關鍵日誌，二是根據數據繪製活躍圖。
提取日誌數據
因為日誌里夾雜了太多不相關的數據，我們需要先進行一波清洗，這個是 sed 的拿手好戲：
$ sed -n '/add action .*\..*/p' gux_log.1.txt

2020-08-31 10:20:14.546 2248 3360 [1] add action GDraw.timer_duration (0)
接下來要從清洗後的日誌中提取日期、時間、進程號、產品標識、操作 5 個欄位到該產品標識對應的文件中，這個是 awk 的分內活兒：
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] }'
因為產品標識與操作是用 ‘.’ 號分隔的，所以要在分隔符中加入點號 (默認為空格)，不過這樣一來，就會把時間和毫秒也分成兩個欄位，所以我們要提取的欄位下標（從 1 開始）就分別變成了日期(1)、時間(2)、進程號(4)、產品標識(9)、操作(10)。提取到的數據行會寫入對應的產品標識命名的文件中 (“plot/GDraw.txt”)，注意這裡的 $9 不能包含在引號中，否則不起作用 (awk 語法補習一下)。並遞增對應的產品標識埋點數據，最後將所有的產品統計資訊列印出來：
GDraw : 34
同時在 plot 子目錄下可以找到以 GDraw 命名的數據文件 (GDraw.txt)：
$ cat plot/GDraw.txt 2020-08-31 10:15:44 2248 GDraw 啟動 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 添加長方形 2020-08-31 10:15:57 2248 GDraw 添加圓 2020-08-31 10:16:03 2248 GDraw 添加圓 2020-08-31 10:16:10 2248 GDraw 添加橢圓 2020-08-31 10:16:14 2248 GDraw 添加多邊形 2020-08-31 10:16:19 2248 GDraw 添加文本 2020-08-31 10:16:24 2248 GDraw 添加直線 2020-08-31 10:16:37 2248 GDraw 設置文本 2020-08-31 10:16:37 2248 GDraw 設置文本 2020-08-31 10:16:37 2248 GDraw 設置文本 2020-08-31 10:16:41 2248 GDraw 置底橢圓 2020-08-31 10:16:41 2248 GDraw 置底文本 2020-08-31 10:16:41 2248 GDraw 置底直線 2020-08-31 10:16:45 2248 GDraw 移動橢圓 2020-08-31 10:16:49 2248 GDraw 刪除圓 2020-08-31 10:16:52 2248 GDraw 刪除圓 2020-08-31 10:16:55 2248 GDraw 粘貼圓 2020-08-31 10:16:59 2248 GDraw 調整圓 2020-08-31 10:17:04 2248 GDraw 調整長方形 2020-08-31 10:17:07 2248 GDraw 調整多邊形 2020-08-31 10:17:11 2248 GDraw 調整弧 2020-08-31 10:17:16 2248 GDraw 調整直線 2020-08-31 10:17:44 2248 GDraw 設置文本 2020-08-31 10:17:44 2248 GDraw 設置文本 2020-08-31 10:17:44 2248 GDraw 設置文本 2020-08-31 10:17:48 2248 GDraw 調整文本 2020-08-31 10:17:55 2248 GDraw 刪除文本 2020-08-31 10:18:07 2248 GDraw 保存文件 2020-08-31 10:18:08 2248 GDraw 關閉文件 2020-08-31 10:18:08 2248 GDraw 退出 2020-08-31 10:20:14 2248 GDraw timer_duration
過濾掉了不相關的內容，顯得清爽多了。這還僅僅是一個產品的埋點數據，如果有多個產品的話，就可以看到更有趣的一些輸出，例如：
GDraw : 93 GTJ2021 : 17 GCCP5 : 70 GCCP6 : 154
每個產品會單獨統計埋點數，同時在 plot 目錄下生成每個產品的數據文件。
不同的日誌格式
以為上面就解決了日誌清洗的所有問題？No！因為程式碼的不斷的調整，曾經出現過三種格式的日誌，下面分別列舉：
v2 [1] 2019-09-19 00:39:24 10772 5992 add action GDQ2018.合併 (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)
具體說我們剛才處理的日誌其實是 v3 版本的，另外還有 v2 版本，這個是最老的日誌，與 v3 的區別是日誌級別是放在最前面的，時間沒有毫秒值；還有 v3.1 版本，這個是最新的日誌，與 v3 的區別是日誌級別之前加了一個模組名稱欄位。這些欄位順序的調整與額外欄位的增加，會導致我們讀取時需要選擇的欄位下標不同，例如下面的 awk 語句分別對應上面三種版本的日誌：
# 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] }'
它們的輸出都是一樣的。好在 awk 支援條件判斷，我們完全可以在一條語句里進行不同版本的日誌處理：
$ 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] }'
被壓扁在一行了，單獨提取 awk 的部分列在下面看著更清晰一些：
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[$9]++ } 5 } 6 7 END { for (i in a) print i " : " a[i] }
新增的部分主要在條件判斷的地方，如果第 1 個欄位符合正則式則走第一個條件的語句，這條正則式是說「方括弧括起來的數字」，就是[1]、[2]、[3]……啦，這是用來匹配 v2 日誌的；如果第 9 個欄位為 「action”，則走第二個條件的語句，這是用來匹配 v3.1 日誌的；剩下的 else 就當然是用來區別 v3 日誌的啦。這樣一來即使一個文件中有不同版本的日誌，也能輕鬆處理。
繪製埋點活躍圖
其實經過日誌清洗後，得到的各產品」純純「的數據，就已經可以交差了，因為沒有什麼是比數據更準確的啦。但是考慮到我面對的人可能是連 Windows 服務在哪裡控制都找不到的人，我決定更進一步，通過各產品的數據繪製一幅直觀的埋點圖，來給用戶一個傻瓜式的體驗（誰叫我懶），先上效果圖：
這個圖的橫軸表示時間，縱軸表示會話，可以認為一個產品啟動到關閉整個過程為一次會話 (通過進程 ID 值代表)。如果對應的時間段有數據點的話，就表示該產品在那個時間活躍過。以上圖為例，如果我們想看 GCCP5 這個產品在哪天活躍過，就可以在圖中查找圖例對應顏色的點，可以看到，大部分集中在 6.10-6.13 這個區間，其它時間段比較少。又例如，我想查看 8.21-8.27 之間有無產品活躍，從圖中看到這段時間區間是一片空白，所以可以確定用戶在這個時間段沒有使用公司的產品。那麼這張圖是怎麼生成的呢，這就需要用到 gnuplot 了，其實我之前寫過的文章有對這個工具使用方法的詳細說明，感興趣的可以參考這篇《查看部落格園積分與排名趨勢圖的工具》。下面直接上程式碼，首先是 shell 腳本部分 (guxplot.sh)：
1 #! /bin/bash 2 arg="logs='" 3 logs=$(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" &
這個腳本的核心是遍歷之前生成數據的 plot 子目錄，將其中 .txt 結尾的數據文件取出，依次放入 arg 參數中，將其作為一個參數 (logs) 傳遞給 gnuplot 腳本 (gux.plt) 去執行。另外它還有一個輸入參數 ($1)，也作為一個參數 (logpath) 傳遞給了 gnuplot 腳本。下面來看繪製程式碼 (gux.plt)：

簡單解讀一下：
- 進行一些基本設置 (line 2-6)；
- 設置橫坐標 (line 7-12)，包括設置時間軸、時間格式、橫坐標刻度等等；
- 設置坐標名稱 (line 15,16)；
- 最後一條語句完成所有繪製 (line 19)。
重點說明一下最後一條，正常的數據繪製是如 line 18 所示，有輸入數據 (log.txt)、有使用的數據列 (using 2:4)、有展現形式 (with points pt 1)、有圖例名稱 (score)。它和 19 行的區別在於，後者是一條循環語句，它遍歷 logs 參數中的所有值並將當前值存放在 log 變數中 (其實就是產品標識啦)，後面它用這個變數拼接出了輸入的數據來源 (例如 plot/GDraw.txt，注意 gnuplot 是使用 ‘.’ 來連接字元串與變數的)；最後還用這個變數命名了圖例的名稱 (title log)；其它和 18 行沒有什麼區別。如果對上一個腳本 guxplot.sh 還有印象的話，它一共傳遞給這個腳本兩個參數：logs 和 logpath，剛剛說明的是前者，後者是用來設置標題的，這樣就能清楚得知數據來源。
把一切串起來
關鍵腳本搞清楚之後，我們就可以做總成了，下面是驅動」一切「的那個腳本 (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.合併 (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!"
簡單解讀一下：
- 首先判斷輸入日誌來源 (line 2-20)，如果在系統目錄下找不到日誌，就在本目錄查找，這樣便於直接分析獲取到的日誌，而不是去用戶機器上裝一個工具。如果都找不到，就沒得可分析，直接退出。這裡系統的話由於WinXP 和 Win7+ 存放的目錄不一樣，所以要區分一下，注意這個腳本雖然是 shell 腳本，但是是運行在 Windows 系統上的，所以一些 windows 的工具和命令也是可以直接調用的 (Wmic)；
- 接著將查找到符合條件的日誌名稱 一 一 列出，供用戶選擇，用戶可以直接回車 (或輸入 0) 表示處理所有日誌輸入，也可以輸入一個序號，表示只處理序號對應的日誌。當用戶只關心最近的日誌數據的話，可以使用後面這個功能來縮小處理的日誌時間範圍，使生成的活躍圖更精確一些；
- 分別處理各個日誌 (line 43-76)，用到了我們前面介紹的 sed 與 awk，注意添加數據時使用的是追加 (>>)，這樣可以避免覆蓋前面生成的數據。同時如果日誌不在當前目錄下面，會自動將日誌也複製到打包目錄，方便萬一有問題時繼續進行分析；
- 如果沒有任何數據文件生成 (line 78-82)，表示日誌中沒有有效的數據，沒得分析，退出；
- 繪製活躍圖 (line 84,85)；
- 將所有的數據和圖表壓縮成一個 tar 包 (line 87-96)，方便後續提交。這時里本來想用 ‘tar cvzf『 一步生成，結果 tar 老是報 gzip 找不到，雖然我已經提供了這個 exe，後來拆分成兩步 (tar + gzip) 就好了，可能是 tar 有它自己的查找方式，在移植到 windows 環境後被破壞掉了。
下面是這個腳本的運行截圖：
運行結束後會自動彈出埋點活躍圖。
結語
其實前面稍微提到了一點，就是我是在 Windows 環境下運行 shell 腳本的，使用的是 msys2，一種類似 cygwin 的東東，我前幾篇文章都有提到過。最終這個日誌清洗工具做好後，我只需要把我用到的 msys2 命令提取出來，就可以在新的機器上運行了，既不用安裝，也不用註冊，完全是個」綠色「版本啊。下面一張工具內容的截圖為證：
其中 exe 除了 bash.exe 外，均為腳本中用到的命令；dll 基本是各個 exe 依賴的文件，這個是通過試運行報錯後一個一個從 msys2 系統扒過來的；bat、sh 與 plt 基本就是我們的腳本文件啦。整個工具佔用空間 23.3 MB，壓縮後僅僅 10 MB 多一點，非常便於給用戶交付，我想這也是 msys2 系統相比於各種腳本語言最大的優勢 —— 不需要安裝龐大的語言虛擬機或運行時庫，用到什麼再添什麼，比較小巧靈活，適合我這種簡單的任務。
