Configure call detail recording and Quality of Experience settings in Skype for Business Server

Summary: Learn how to configure CDR and QoE in Skype for Business Server.

Configure CDR and QoE monitoring using SQL Server Reporting Services reports for Skype for Business Server.

Configure CDR and QoE

After you is associated a monitoring store with a Front End pool, set up the monitoring store, and then installed and configured SQL Server Reporting Services and Monitoring Reports you can manage Call Detail Recording (CDR) and Quality of Experience (QoE) monitoring by using Skype for Business Server Management Shell. Skype for Business Server Management Shell cmdlets allows you to enable and disable CDR and/or QoE monitoring for a particular site or for your entire Skype for Business Server deployment; that can be done with a command as simple as this:

Set-CsQoEConfiguration -Identity "global" -EnableQoE $False

When you install Skype for Business Server, you also install a predefined collection of global configuration settings for both CDR and QoE. Default values for some of the more commonly used settings used by Call Detail Recording are shown in the following table:

Property	Description	Default Value
EnableCDR	Indicates whether or not CDR is enabled. If True, all CDR records are collected and written to the monitoring database.	True
EnablePurging	Indicates whether or not CDR records are periodically deleted from the database. If True, records will be deleted after the time period specified by the properties KeepCallDetailForDays (for CDR records) and KeepErrorReportForDays (for CDR errors). If False, CDR records are maintained indefinitely.	True
KeepCallDetailForDays	Indicates the number of days that CDR records will be kept in the database; any records older than the specified number of days will automatically be deleted. However, this occurs only if purging is enabled. KeepCallDetailForDays can be set to any integer value between 1 and 2562 days (approximately seven years).	60 days
KeepErrorReportForDays	Indicates the number of days that CDR error reports are kept; any reports older than the specified number of days is automatically deleted. CDR error reports are diagnostic reports uploaded by client applications such as Skype for Business Server. You can set this property to any integer value between 1 and 2562 days.	60 days

Similarly, default values for selected QoE settings are shown in this table:

Property	Description	Default Value
EnableQoE	Indicates whether or not QoE monitoring is enabled. If True, all QoE records are collected and written to the monitoring database.	True
EnablePurging	Indicates whether or not QoE records are periodically deleted from the database. If True, records are deleted after the time period specified by the KeepQoEDataForDays property. If False, QoE records are maintained indefinitely.	True
KeepQoEDataForDays	Indicates the number of days that QoE records are kept in the database; any records older than the specified number of days will automatically be deleted. However, this will occur only if purging has been enabled. KeepCallDetailForDays can be set to any integer value between 1 and 2562 days.	60 days

When you need to modify these global settings you can do so by using the Set-CsCdrConfiguration and the Set-CsQoEConfiguration cmdlets. For example, this command (run from within the Skype for Business Server Management Shell) disables CDR monitoring at the global scope; that's done by setting the EnableCDR property to False ($False):

Set-CsCdrConfiguration -Identity "global" -EnableCDR $False

Disabling monitoring doesn't dissociate the monitoring store from the Front End pool, nor does it uninstall or otherwise affect the backend monitoring database. When you use Skype for Business Server Management Shell to disable either CDR or QoE monitoring all you really do is temporarily stop Skype for Business Server from collecting and archiving monitoring data. If you want to resume, in this case, the collection, and archiving of CDR data, all you need to do is set the EnableCDR property back to True ($True):

Set-CsCdrConfiguration -Identity "global" -EnableCDR $True

Similarly, this command disables the purging of QoE records at the global scope:

Set-CsQoEConfiguration -Identity "global" -EnablePurging $False

In addition to the global settings, CDR and QoE configurations settings can be assigned to the site scope. This provides more management flexibility when it comes to monitoring; for example, an administrator can enable CDR monitoring for the Redmond site but disable CDR monitoring for the Dublin site. To create new CDR configuration settings at the site scope, use a command similar to this:

New-CsCdrConfiguration -Identity "site:Redmond" -EnableCDR $False

Keep in mind that settings configured at the site scope take precedence over settings configured at the global scope. For example, suppose CDR monitoring is enabled at the global scope, but disabled at the site scope (for the Redmond site). That means that call detail recording information won't be archived for users in the Redmond site. However, users in other sites (that is, users managed by the global settings instead of the Redmond site settings) have their call detail recording information archived.

New QoE configuration settings can be created at the site scope by using a command like this one:

New-CsQoEConfiguration -Identity "site:Redmond" -KeepQoEDataForDays 15
