Analying The Change Frequency Of Active Users Tokens From Tomcat Logs

接到Java開發人員的需求,從Tomcat日誌中提取最近一個月查詢、購票活躍度最高的5位iOS用戶的token變更頻率。日誌文件在線上生產服務器中，單個文件高達十數GB，無法使用vim打開，只能下載到本機後再進行數據提取操作，以下是完整的記錄。

Requirements

需求整理如下

Target

提取最近一個月(2016.11.01~30, 2016.12.01)查詢、購票活躍度最高的5位iOS用戶的token變更頻率

Data Source

Active Users’ Info

活躍用戶信息查詢，SQL語句由Java開發人員提供 (SQL語句似乎有問題,沒有判斷是否屬於iOS用戶)

1

select a.* from t_bus_member a join (select member_id,count(1) sum from t_bus_ticket where create_time >= '2016-11-1' and create_time <'2016-12-1' and ticket_status = 2 group by member_id order by sum desc limit 5) b on a.id = b.member_id\G

其中含有需要的設備ID (t_bus_member.mac_id)

Data Source File

INFO : (LoggerAspect.java:48)    请求方法：void com.raxtone.flybus.rpc.rmi.user.IPushTSRmiService.sendTokenToSerer(TokenParam,String,Integer,Integer)，请求参数：[{"cityId":0,"token":"80275d72bebcbf9c0d9d5c4f62c7b15e90c6795c5a4a58af79f4f57f47a7590f"},"cb0eeb6990335140b8f65fb3fc9a3f522de48b35",11,100]

按如下要求在日誌文件中查詢匹配數據

含有關鍵詞 sendTokenToSerer；
同時含有設備ID，示例中的cb0eeb6990335140b8f65fb3fc9a3f522de48b35；

提取其中的日期，設備ID，token值，在示例中分別是

item	details
date	`2016-12-01 00:07:39`
mac_id	`cb0eeb6990335140b8f65fb3fc9a3f522de48b35`
token	`80275d72bebcbf9c0d9d5c4f62c7b15e90c6795c5a4a58af79f4f57f47a7590f`

Output Format

結果輸出格式 時間|設備編號|token

2016-12-01 00:07:39|cb0eeb6990335140b8f65fb3fc9a3f522de48b35|80275d72bebcbf9c0d9d5c4f62c7b15e90c6795c5a4a58af79f4f57f47a7590f`

Analysis

Step1 Active Users’ Info

查詢、購票活躍度最高的5爲iOS用戶的設備ID由開發人員提供的SQL語句獲取。

Step2 Download Log Files

原始日誌文件總大小達16GB，在生產服務器上進行數據提取操作會對線上業務造成影響；通過sftp將相關日誌拉取到本地進行處理，保存路徑爲/tmp/flybusProvider。

Step3 Merge Line

日誌中請求日期和請求體在相鄰的兩行中，須將其合併爲一行，只對指定時間範圍內的數據進行操作，使用命令awk及其中的getline方法實現；
