Enable Usage and Health Data Collection
Enable Usage and Health Data Collection best practices report by SPDocKit determines whether the SharePoint Usage and Health Log data collection is enabled
This check determines whether the SharePoint Usage and Health Log data collection is enabled. This can provide an insight into the functioning of the system itself; however, it can also introduce additional load to the system and fill the hard drive on which the log files are stored.
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.
Make sure that only required events are selected for the data collection. 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 log settings. In the case you want to turn off the Usage and Health data collection, under Health Data Collection clear the check box near Enable Health Data Collection and click OK.
