Faster log explorer
klogg is a multi-platform GUI application to search through all kinds of text log files using regular expressions. It is fork of glogg project created by Nicolas Bonnefon.
klogg is designed to:
- be fast
- handle huge log files
- provide a clear view of the matches even in heavily cluttered files.
General usage can be described as simple loop:
graph TD; A[Search for some regular expression]-->B[Mark interesting lines to keep in results window]; B-->A;
Using this pattern you can get full picture of what was happening at the time of logging.
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)
- Is open source, released under the GPL
klogg improves and brings more
- Builds initial file index significantly faster
- Uses multiple CPU cores to do regular expression matching
- Detects log file encoding using uchardet library (support utf8, utf16, cp1251 and more)
- Allows to perform search in a portion of huge log file
- Keeps in-memory cache of search results per search pattern
- Allows to paste some text from clipboard for further analysis
- Has portable version for Windows (no need to install)
