To change logging settings by using Lync Server Control Panel

  2. In the left navigation bar, click Clients, and then click Device Log Configuration.

  3. On the Device Log Configuration page, double-click the configuration that you want to change.

  4. In the Edit Log Setting dialog box, change any of the following settings:

    • Maximum file size (bytes)   Specifies the maximum size a log file can become before it is purged. The default is 1,024,000 bytes (1 MB).

    • Maximum cache size (bytes)   Specifies the maximum amount of information (in bytes) that can be held in the log file cache before that cache must be cleared and the data is written to a log file. The default is 512,000 bytes (0.5 MB).

    • Number of minutes to flush cache (1-60)   Indicates how often information stored in the log file cache is written to the actual log file. After the data is logged, the cache is cleared. The default is five minutes.

    • Number of days to keep log files (1-365)   Specifies the number of days the log files are kept before they are purged. The default is 10 days.

  5. Click Commit.

Changing Logging Settings by Using Windows PowerShell Cmdlets

Device update log file settings can be modified by using Windows PowerShell and the Set-CsDeviceUpdateConfiguration cmdlet. This cmdlet can be run either from the Lync Server 2013 Management Shell or from a remote session of Windows PowerShell.

Note:
For details about using remote Windows PowerShell to connect to Lync Server, see the Lync Server Windows PowerShell blog article "Quick Start: Managing Microsoft Lync Server 2010 Using Remote PowerShell" at http://go.microsoft.com/fwlink/p/?linkId=255876.

The following examples show a couple of the ways that you can use Set-CsDeviceUpdateConfiguration to modify settings.

To modify the maximum log file size and the log cleanup interval

  • The following command modifies the device update log settings applied to the Redmond site. In this example, the maximum log file size is set to 204800 bytes and the log cleanup interval is set to 14 days.

    Copy Code 
    Set-CsDeviceUpdateConfiguration -Identity "site:Redmond" -MaxLogFileSize 204800 -LogCleanUpInterval 14.00:00:00

To modify the log cleanup time of day

  • This command sets the log cleanup time for the Redmond site to 3:00 AM.

    Copy Code 
    Set-CsDeviceUpdateConfiguration -Identity "site:Redmond" -LogCleanupTimeOfDay 03:00

For details, see the Help topic for the Set-CsDeviceUpdateConfiguration cmdlet.
