Log Parser Lizard provides a modern graphical user interface to MS Log Parser 2.2 for analyzing logs using SQL queries

Page updated October 15, 2018 by Lizard Labs Software


Log Parser Lizard provides a great Graphical User Interface (GUI) to Microsoft Logparser 2.2. No cloud or web server needed. It is a versatile desktop tool that gives automated SQL query access to any system log or text-based data including Web Server Logs (IIS, Apache, W3C, SharePoint, MS Exchange, FTP, etc…), Windows System Events and even application log files (generated with log4net, Nlog, SeriLog, etc.). Also great for Data Visualization (dataviz), Business Intelligence (BI) and Extract Transform Load (ETL) tasks.


When was the last time you have checked the log files for suspicious activity? Now would be a good time to review them!





Log Parser is wonderful because it effectively lets you run SQL queries against text files:


SELECT DISTINCT src-ip FROM pfirewall.log WHERE action='DROP'

SELECT cs-uri-stem FROM c:\InetPub\Logs\ex*.log
GROUP BY cs-uri-stem HAVING COUNT(*) > 50

SELECT to_lowercase(extract_extension(cs-uri-stem)) AS PageType, SUM(sc-bytes)
FROM ex131118.log, ex131119.log GROUP BY PageType


And Log Parser Lizard is wonderful because it shows that data in a beautiful GUI:


Log Parser Lizard is a GUI for Microsoft Logparser, definitely the best one available on the market today. Log Parser is a very powerful and versatile query software tool that provides universal query access (using SQL) to text-based data, such as log files, XML files, and TSV/CSV text files, as well as key data sources on the Microsoft Windows operating system, such as the Windows Event Log, IIS log, the registry, the File System, the Active Directory services and much more.


Microsoft Logparser is an enhanced query software that digs through information in log files seamlessly and efficiently using SQL queries without storing log data into database.
