Get lines from a number of log files with different time-stamp formats in chronological order
Project description
Mingle is a library and command line tool to allow you to read from many log files, line by line in chronological order.
Introduction
Mingle uses the python-dateutil module to flexibly attempt to parse the first part of each line as a datetime, and provides a generator to access the lines in total chronological order, across the input files.
It also offers a function to conveniently print the lines out in chronological order, optionally marking which files the lines come from.
A command line utility ‘mingle’ is also provided, to print the log file lines in chronological order from the shell.
Usage:
To access a generator that will return lines from multiple log files in chronological order:
>>> from mingle import mingled >>> files = ['webserver-log', 'db-log', 'firewall-log'] >>> for line, filename in mingled(files): >>> print("The line: " + line) >>> print("From file:" + filename)
To conveniently print the lines to stdout:
>>> import mingle >>> files = ['webserver-log', 'db-log', 'firewall-log'] >>> mingle.cat(files)
To print the usage of the command line interface:
user@localhost:~$ mingle -h usage: mingle [-h] [-q] files [files ...] Inter-mingle the contents of several log files by date stamp. positional arguments: files the files to intermingle optional arguments: -h, --help show this help message and exit -q, --quiet strip the filename annotations from the output
