check_in_logfiles.py

Hi, Hope you don't mind. I modified the code a bit.
Seemed that when everything was OK, Nagios failed display data.

#!/usr/bin/env python
# Check_log_files.py
# Author: Imran Ahmed
# Description: Nagios plugin that searches log files for a patterns loaded from a pattern file.
# Usage check_in_logfiles.py :
# First argument PATTERNFILE is a text file containing lines of the form:
# SEVERITY:PATTERN
# where *SEVERITY* is one of `IGNORE`, `WARNING`, `CRITICAL` and *PATTERN* is a
# regular expression.
# Second (and later) argument LOGFILE is the path to one (or more) log files.
# if a line is found that matches a *PATTERN* with *SEVERITY* `CRITICAL`,
# exit with CRITICAL status
# if a line is found that matches a *PATTERN* with *SEVERITY* `WARNING`,
# exit with WARNING status


import sys, re

def popLists(file):
with open(file, 'r') as myPatFile:
lines = myPatFile.readlines()
critical = []
warning = []
ok = []
for line in lines:
line = line.strip()
words = line.split(":")
if (words[0] =='CRITICAL'):
critical.append(words[1])
elif (words[0] =='WARNING'):
warning.append(words[1])
elif (words[0] =='OK'):
ok.append(words[1])
else:
print "Everything is cool!"
return critical, warning, ok

argc = len(sys.argv)
if argc main()
