Log4net logs software: Monitoring IIS Logs, SQL Logs, Event Viewer, Monitors NT event and text log files, Monitors event logs and sends email alerts and more.
Becouse the command line interface of MS Log Parser is not very intuitive, I have created Log Parser Lizard, a GUI tool for managing queries, exporting results to Excel, charts, etc... In addition it provides input filters for log4net file format (with support for regular expressions) and SQL server T SQL queries.
