  • Article

 

Applies to: SharePoint Server 2010

Alert Name:   ULS usage log reaching maximum size

Event ID:   8095

Summary:   The SharePoint 2010 Tracing Service (SPTracev4) is used by Microsoft SharePoint Server 2010 to manage usage log output. When usage logging is enabled, administrators can specify the path used to store the usage log file. This log file is used by many applications that are built on SharePoint Server 2010. This event occurs when the configured log file location is low on space. It serves as a warning that logging may stop soon unless more space is made available or the space allocated to logging is increased.

Symptoms:   This event appears in the event log: Event ID: 8095 Description: Usage logs are reaching to the configured storage limit [configured limit]. Please increase the maximum storage settings. Otherwise, older files will be deleted once the limit is reached.

Cause:   The configured log file location has insufficient free disk space for logging, or the maximum space allocated for logging is too low.

Resolution:   Increase the space limit for log files

  1. Verify that the user account that is performing this procedure is a member of the Farm Administrators group.

  2. On the Central Administration Home page, click Monitoring.

  3. In the Reporting section, click Configure usage and health data collection.

  4. On the Configure web analytics and health data collection page, in the Usage Data Collection Settings section, type a larger number of gigabytes (GB) to allocate to the log files. When log files reach this size on the disk, older log files will automatically be deleted.

  5. Click OK.

Resolution:   Change the location of the log file

  1. On the Central Administration Home page, click Monitoring.

  2. In the Reporting section, click Configure usage and health data collection.

  3. On the Configure web analytics and health data collection page, in the Usage Data Collection Settings section, type a new location for the log file on a drive or partition that has sufficient disk space.

  4. Click OK.

Resolution:   Free disk space

  1. Run the Disk Cleanup tool to free disk space where the usage log files are stored.

  2. Verify that the usage logging service has sufficient disk space to write the log file.

  3. If the usage logging service has insufficient disk space to write the log file, delete the contents of the Temp folders on the drive.

To check the usage log file

  1. On the Central Administration Home page, click Monitoring, and in the Reporting section, click Configure usage and health data collection.

  2. On the Configure web analytics and health data collection page, in the Usage Data Collection Settings section, copy the path of the usage log file.

  3. In Windows Explorer, navigate to the usage log file by using the copied path. Usage log files are in binary format and the contents cannot be easily viewed and understood. The file size of the usage log increases over time and confirms that usage logging is working.
