Project description

https://img.shields.io/pypi/v/general-log-parser.svg

Introduction

General log parser is a tool for simple parsing of log files line by line. It assumes your log is in the form of a series of strings separated by tab or some kind of special field separator.

It offers 2 modes:

  • Parsing from standard input.
  • Parsing from a file or a list of files.

Usage examples

Uses the test files from the tests folder.

Parse from standard input

cat tests/a20150505.log | logparser

Parse from single file

logparser -l tests/a.20150505.log

Parse from a list of files

logparser -l a.{}.log --from 20150501 --to 20150506 --input-dir tests

Get all lines contains ‘server1’

logparser -l tests/a.20150505.log --line-filter server1

Get all lines contains ‘server1’ OR ‘server2’

logparser -l tests/a.20150505.log --line-filter server1 --line-filter server2

Get all lines which does NOT contains ‘server1’

logparser -l tests/a.20150505.log --not-line-filter server1

Get all lines where the third field > 9939928

logparser -l tests/a.20150505.log --cond-filter "{2} > 9939928"

Get all lines print only the second and third fields

logparser -l tests/a.20150505.log --line-filter server1 -o "{1} {2}"
