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 https://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.
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.
Set-CsDeviceUpdateConfiguration -Identity "site:Redmond" -LogCleanupTimeOfDay 03:00
For details, see the Help topic for the Set-CsDeviceUpdateConfiguration cmdlet.
