Log analysis is important to both troubleshoot and understand network devices behavior.

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  is a Windows tail program (a GUI replacement for the Unix tail command). LogExpert is free for non-commercial or commercial use.

An alternative multi platform choice is _glogg  _that is under active development:

<em>glogg</em>  is a multi-platform GUI application to browse and search through long or complex log files. It is designed with programmers and system administrators in mind. glogg can be seen as a graphical, interactive combination of grep and less.

Happy log analysis!
