Subject IBSurgeon Log Viewer: free tool to view and analyze firebird.log
Author Alexey Kovyazin
IBSurgeon Log Viewer is designed to facilitate viewing and analyzing long Firebird and InterBase logs.
Many Firebird and Interbase developers and administrators do not pay enough attention to the contents of firebird.log, though there is a lot of useful information, which can help to find and resolve various issues with Firebird/InterBase databases.

Originally Log Viewer was IBSurgeon's internal application, which helped to quickly navigate through very long Firebird and InterBase logs, and in version 2.0 it became mature enough to be released for the community.
