Log Size Control

Aqui está um script, que funciona em Windows e em Linux, e que ajuda a "controlar" o tamanho dos ficheiros de log que queira monitorizar.

O script vai buscar os dados dos logs que querem monitorizar ao ficheiro loglist.data

Código:

import os, bz2, sys

# Log Size Control 100% cross platform (windows/linux);   #
#               Take the files for array                  #
#               Check the size if its bigger them         #
#               max_size compress to bz2 file             #
#                                                         #
