As the website states "Apache Logs Viewer (ALV) is a free and powerful tool which lets you monitor, view and analyze Apache/IIS logs with more ease. It offers search and filter functionality for the log file, highlighting the various http requests based on their status code. There is also a report facility, thus you can generate a pie/bar chart in seconds. Together with this there are also statistics where you can get the top hits, top errors, number of status codes, total bandwidth and more."
