Faster log explorer #

klogg is an open source multi-platform GUI application to search through all kinds of text log files using regular expressions. It has started as fork of glogg project created by Nicolas Bonnefon, and has evolved into a separate project with a lot of new features and improvements.

klogg is designed to:

  • be very fast
  • handle huge log files
  • provide a clear view of the matches even in heavily cluttered files.

Here is what klogg looks like:

Features #

klogg inherited a lot of features from glogg

  • Runs on Unix-like systems, Windows and Mac thanks to Qt5
  • Displays search results separately from original file
  • Supports Perl-compatible regular expressions
  • Colorizes the log and 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
  • Watches for file changes on disk and reloads it (kind of like tail)

klogg improves and brings more

  • Is optimized for modern CPUs with multiple cores and SIMD instructions
  • Has portable version (no need to install)
  • Understands a lot of text encodings and detects many of them automatically
  • Allows to perform search in a portion of huge log file
  • Supports multiple sets of text highlight rules with more sophisticated match options
  • Provides many small features to make life easier (tab renaming, favorite files list, archive extraction, scratchpad etc.)
