QLogExplorer\n\nAdvanced tool for exploring log files.\n\n![image](screenshots/main.png?raw=true)\n\n## Main features\n\n### Very fast and can handle huge files\n\nThe file is not loaded into memory, but indexed by chunks.\nIt allows a very fast loading, as well as low memory consumption, even when a large file is opened.  \n`QLogExplorer` also allows to browser the file and to start searching even when the file is still being indexed.\n\n### No locks whatsoever\n\nA monitoring applications shall never interfere with the process that is generating/managing the logs, therefore the process must be able to delete, move or compress the log files without getting any denied operation due the monitoring application is reading it.  \n`QLogExplorer` never interferes in the log management process.\n\n### Supports JSON log files\n\nNowadays it's very common log files to be in JSON format as follow:\n```json\n{\"LogLevel\":\"INFO\",\"DateTime\":\"28-12-2021 18:03:54.00274\",\"LogMessage\":\"System initialized\"}\n{\"LogLevel\":\"WARNING\",\"DateTime\":\"28-12-2021 18:03:54.00301\",\"LogMessage\":\"Not in UTC\"}\n{\"LogLevel\":\"ERROR\",\"DateTime\":\"28-12-2021 18:03:56.00885\",\"LogMessage\":\"Exception caught\"}\n```\n`QLogExplorer` completely supports that kind of log format.\n\n[See wiki for further information](https://github.com/rafaelfassi/qlogexplorer/wiki/JSON-Files-Support)\n\n### Templates\n\nDifferent systems may have different kind of log info, so a template can be created for each kind of log, having:\n\n* Columns definition.\n* Highlighters definition.\n* Predefined search parameters.\n\n[See wiki for further information](https://github.com/rafaelfassi/qlogexplorer/wiki/Templates)\n\n### Advanced search\n\nThe search allows multi-parameters where the parameters can be combined by `AND` or `OR` operators.  \nEach parameter can:\n\n* Have the search expression as `SubString`, `Regex` or `Range`.\n* Be limited to a specific column.\n* Use the negation operator.\n\n[See wiki for further information](https://github.com/rafaelfassi/qlogexplorer/wiki/Searching)\n\n## Build\n\n__Minimum requirements__\n\n* C++ 17\n* CMake 3.10\n* Qt 6.4\n\nIf not using Qt creator, make sure the Qt dir is in the PATH.  \nTo build the project via command line:\n```\nmkdir build\ncd build\ncmake ../\nmake\n```\n","funding_links":[],"categories":["C++"],"sub_categories":[],"project_url":"https://awesome.ecosyste.ms/api/v1/projects/github.com%2Frafaelfassi%2Fqlogexplorer","html_url":"https://awesome.ecosyste.ms/projects/github.com%2Frafaelfassi%2Fqlogexplorer","lists_url":"https://awesome.ecosyste.ms/api/v1/projects/github.com%2Frafaelfassi%2Fqlogexplorer/lists"}
