tbgrep 0.3.0

从大量文件中提取tracebacks

$ tbgrep file1 file2 file3

在管道中搜索tracebacks

$ tail -f logfile | tbgrep

按出现次数排序显示所有唯一的tracebacks

$ tbgrep --stats logfile
[...]

== 99 occurences ==================================================

Traceback (most recent call last):

733 unique tracebacks extracted

使用Python API

实例化后，将每一行传递给process方法，该方法将返回None或一个traceback字符串。

from tbgrep import TracebackGrep

extractor = TracebackGrep()
for line in file('logfile'):
    tb = extractor.process(line)
    if tb:
        print(tb)

tbgrep还支持生成关于文件中所有tracebacks的统计信息，而不是显示文件中找到的每个traceback。

extractor = TracebackGrep(stats=True)
for line in file('logfile'):
    extractor.process(line)
extractor.print_stats()

还有一些函数允许您以更方便的方式搜索tracebacks。

from tbgrep import (
    tracebacks_from_lines, tracebacks_from_file,
    last_traceback_from_file)
for tb in tracebacks_from_file(file('logfile')):
    print(tb)
for tb in tracebacks_from_file(file('logfile'), reverse=True):
    print(tb)
print(last_traceback_from_file(file('logfile')))

支持的输入格式

tbgrep可以从各种格式的日志中提取堆栈跟踪。例如，CherryPy从带有其他详细信息（如模块、时间戳等）的行开始堆栈跟踪，但其余的堆栈跟踪从行的开头开始。另一方面，Apache日志将为堆栈跟踪的每一行添加此信息。tbgrep旨在处理这类情况
