Glogg – Fast and Smart Log Explorer Tool

Glogg is a multi-platform GUI application that helps browse and search through long and complex log files. It is designed with programmers and system administrators in mind and can be seen as a graphical, interactive combination of grep and less.

The tool enables you to use regular expressions to search for interesting events in your log files. It presents a results window which, together with complex regular expressions allows easy isolation of the meaningful lines amongst the noise.

Glogg – Fast and Smart Log Explorer

glogg has been primarily developed to help spot and understand problems in huge logs generated by embedded systems. It can be equally useful to a sysadmin digging through logs from databases or web servers.The main design goals for glogg are:

  • it should be fast
  • it does not have any limit on the size of files it can handle
  • it provides a clear view of the matches even in heavily cluttered files.

Main features include the following:

  • Runs on Unix-like systems, Windows and Mac thanks to Qt
  • Provides a second window showing the result of the current search
  • Supports grep/egrep like regular expressions
  • Colorizes the log and the search results
  • Displays a context view of where in the log the lines of interest are
  • Is fast and reads the file directly from disk, without loading it into memory
  • Follows a log that is written to disk in real time
  • Allow to insert marks in the logs to interesting lines
  • Supports vim/less like keyboard commands to move around the file
  • Is open source, released under the GPL
