Log Analyzer

It's the python script which parses log4net logs and returns the stats related to the log levels and error messages.

import pprint
from colorama import Fore, init
from simple_log_parser import SimpleLogParser

error_stats = SimpleLogParser('./log.txt').errors_count(from_date='2021-04-15')

init(autoreset=True)
print(Fore.GREEN + 'Error Levels:')
pprint.pprint(error_stats[0])
print(Fore.GREEN + 'Error Messages:')
pprint.pprint(error_stats[1])

The code above prints this:

Error Levels:
defaultdict(<class 'int'>, {'ERROR': 6})

Error Messages:
defaultdict(<class 'int'>,
            {'Microsoft.AspNetCore.Connections.ConnectionResetException: The client has disconnected\n': 1,
             "System.ArgumentException: 'A' is invalid": 1,
             "System.ArgumentException: 'B' cannot be > 4": 1,
             "System.Data.SqlClient.SqlException (0x80131904): Error 2601, Level 14, State 1, Procedure ...": 1,
             'System.NotImplementedException: The method or operation is not implemented.\n': 2})
