Send these log files to [support@navvis.com](https://knowledge.navvis.com/docs/support@navvis.com) for analysis. [Get logs](https://player.vimeo.com/video/1071051525?h=13557bd07d&badge=0&autopause=0&player_id=0&app_id=58479) ## Types of Log Files There are two types of log files: - Dataset-specific log files - Global (dataset-independent) log files ## Dataset-Specific Log Files These contain all the information messages from the scan, processing, and image stitching. The log files are stored under logs in every dataset, e.g. /path/to/project/datasets_rec/2015-04-28_15.55.23/logs/. For most support tasks, the relevant log files are: | **File name** | **Description** | | --- | --- | | datasets_rec//logs/mapping.log | System software log capturing all log messages during a specific dataset from start to finish. | | datasets_rec//logs/kern.log*.gz | Kernel log of the underlying operating system. | | datasets_rec//logs/syslog*.gz | System log of the underlying operating system. | | datasets_rec//logs/*_NavVis.log.gz | System software log capturing all log messages in a day upon powering the device on. | | ![](https://cdn.document360.io/bf174766-fa1a-4fe1-a4d7-b1db1e7cb996/Images/Documentation/log-files-image-x423d4al.png) | ![](https://cdn.document360.io/bf174766-fa1a-4fe1-a4d7-b1db1e7cb996/Images/Documentation/log-files-image-f1b46rvw.png) | | --- | --- |
