By default, Quality of Experience (QoE) data is purged after 60 days. You can use the settings on the Quality of Experience Data page to retain the data for a longer or shorter period of time. If you disable QoE, data that was captured before QoE was enabled will also be subject to purging.

You should configure call detail recording (CDR) and QoE to retain data for the same number of days. Each call in the call detail reports (CDRs), available from the Monitoring Server reports homepage, includes CDR and QoE information. If the purging duration for CDR and QoE is different, some calls may only include CDR data, while other may only include QoE data.

The following procedure describes how to configure purge settings for QoE data.

To specify retention of QoE data

  1. Log on to the computer as a member of the RTCUniversalServerAdmins group, or as a member of the CsVoiceAdministrator, CsServerAdministrator, or CsAdministrator role. For details, see Delegate Setup Permissions.

  2. Open a browser window, and then enter the Admin URL to open the Lync Server Control Panel. For details about the different methods you can use to start Lync Server Control Panel, see Open Lync Server Administrative Tools.

  3. In the left navigation bar, click Monitoring and Archiving, and then click Quality of Experience Data.

  4. On the Quality of Experience Data page, click the appropriate site from the table, click Edit, and then click Show Details.

  5. To turn on purging, select Enable Purging for Monitoring Servers.

  6. In Keep call detail recordings for maximum duration (days): select the maximum number of days that QoE data should be retained.

  7. Click Commit.
