Log analysis GUI tools

Log analysis is important to both troubleshoot and understand network devices behaviour. Tail/less/grep are great tools that can help to filter and search hundreds or thousands lines of logs. If you prefer a GUI there are a couple of alternatives that can fit well. For windows users only Log Expert is a great choice with many features but it is not developed since 2012. [Log Expert](http://www.log-expert.de/) is a Windows tail program (a GUI replacement for the Unix tail command).
