如何從java日誌文件中提取異常？

我有很多例外的一個巨大的日誌文件，我需要之前和之後提取完整的堆棧跟蹤和幾行。這將是完美的，如果這個工具是bash腳本。例如：如何從java日誌文件中提取異常？

您需要提供一些更多的信息，也許日誌和預期輸出。作爲一個開始看看'grep'和'-A，'-B'切換描述多少行後/應顯示在比賽前。 – 2012-02-16 12:13:50

輸出量是多少？ – kev 2012-02-16 14:17:33

使用awk：

BEGIN { 
    previous = ""; 
} 
/^\tat/{ 
    if(previous != "") { 
     print previous; 
    previous = ""; 
    } 
    print; 
    next; 
} 
{ previous = $0; }

應該做的伎倆。概括地說，查找圖案\tat（選項卡，在空白），其幾乎總是在堆棧跟蹤使用。

如果你有很多例外，那麼你可以使用地圖（關聯數組在AWK的行話）保存異常消息的一部分，然後進行統計（如其中發生異常的最）。

非常感謝！但awk對我來說是新的，是的，我有很多例外，你可以用地圖來展示例子嗎？謝謝！ – 2012-02-17 08:07:50

你可以嘗試這樣的事情，

======= 
grep -B20 -A20 ^'$16.02.2012 16:04:34' <path/to/log/file> 
======= 

Where 
-B20 -- will display 20 lines before the line where the match was found. 
-A20 -- will display 20 lines after the line where the match was found.

大多數Java異常塊行是先從TAB分隔符。

因此，要獲得從您可以使用grep TAB分隔符一個巨大的日誌文件中的所有異常。

使用以下命令從文件中grep的所有異常：

**$ grep -P -A 15 -B 15 "^\t" inputLogFile**
