Usage and Health Log Path best practices report by SPDocKit determines whether the SharePoint Usage and Health Log Files are stored on the primary drive.
This check determines whether the SharePoint Usage and Health Log Files are stored on the primary drive.
SharePoint writes usage and health data to the logging folder and logging database. Usage and Health logs can be used to trace various events, like File I/O, SQL I/O usage, Page Requests, SQL Latency usage and many more. Default location of the logging folder is C:/Program Files/Common Files/Microsoft Shared/Web Server Extensions//LOGS. Depending on the number of users accessing the system and the logging events configured, writing to a log can have a massive impact on the file system’s performance. Therefore, it is highly recommended that trace logs be stored on a dedicated drive.
Make sure that the trace log files are not stored on the same drive as the primary (system) drive or the paging file. To do so, go to the Central Administration > Monitoring > Reporting > Configure usage and health data collection. You can use this page to configure logging level and trace log settings. Specify a new location under Usage Data Collection Settings > Log file location and click OK.
Please note that this is a farm wide setting. This means that the path you specify here must be physically available and accessible on each SharePoint server in your farm.
