玩轉Vista/Windows7下老格式事件日志分析

【注意,本文不適合初級電腦用戶】

如果有一個,一個朋友對你說他的電腦出現了問題,可能,你需要去分析它的系統的事件日志。畢竟,在Windows系統裡面,系統事件日志裡面記錄了太多的信息,應用程序的使用、崩潰等記錄,Windows系統的各種事件記錄等等。然而,當你的朋友把他的Windows目錄下的日志發過來,你想進行查看分析的時候,卻發現,提示事件日志崩潰!

這是怎麼回事呢?

原因很簡單,Vista之前事件日志是.evt文件,Vista及之後是.evtx文件!

我們可以用微軟提供的Log Parser 2.2(點擊進入微軟官方頁面),它能在相應的系統上解析各自支持的格式,解析命令為:

logparser -i:EVT "SELECT * INTO a.csv FROM b.evt"

但如果在Vista、Windows Server 2008、Windows7及之後系統上解析.evt格式日志可能會提示事件日志崩潰,這時需要將.evt格式轉換為.evtx格式,幸運的是Vista及之後的系統提供了Wevtutil-Windows Events Command Line Utility這個工具!

運行命令:wevtutil epl application.evt application.evtx /lf:true 就能轉化。
