Hundred of thousands crash reports are collected from Fedora and CentOS users every day by Automatic Bug Reporting Tool. Processed data are sent to Fedora Analysis Framework server and used by developers and operating system component maintainers to find common problems. Fedora Analysis Framework provides statistic data and a basic way to filter them. The aim of this thesis is to design and implement tool to sort, filter and join the reports, which will help developers to prioritize their work. The design of this toolset is based on existing solutions, issues reported in Fedora Analysis Framework project repository and information provided by its users.
