126CHAPTER 10: USING QOS MONITORING

XML Accounting

The XML Accounting Server collects, and is where you view, the QoS

Server

reports generated by the VCX Call Processor.

On the XML Accounting Server you can:

■Set QoS collection parameters, which determine when the system issues Warning or Critical severity traps based on QoS measurements

■View call history

■View phone statistics

■View Quality Detail Reports (QDRs)

Settings QoS Use the QoS Collection Parameters tab to specify when the Accounting Collection Parameters Server issues Warning or Critical severity traps based on QoS measurements.

To set QoS Collection parameters:

1From the EMS client Explorer tree, select the accounting server.

2From the Properties tab, click the QOS Collection Parameters tab.

3Specify a threshold value for each attribute.

For a description of each attribute, see Table 36. For complete details of each attribute, view the context-sensitive help in EMS.

Description

 

 

BucketSizeMultiplier

Determines the size of the rate-limit bucket. The rate-limit

 

bucket is multiplied by either of the

 

vcxQoSRateLimitMaxWarnings or vcxQoSRateLimitMaxAlarms

 

to produce a rate-limit bucket value.

 

 

Computed

Specifies a threshold for QoS alarms based on computed

MOSValueSevereAlarm

mean option scores (MOS). A value of zero disables this

Threshold

threshold.

 

 

ComputedMOSValue

Specifies a threshold for QoS warnings based on computed

WarningThreshold

mean opinion scores (MOS). A value of zero disables this

 

threshold.

 

 

EndpointCallHistory

Specifies the number of most recent calls to use to

Depth

compute the running-average for QoS performance

 

metrics. The running-averages are made available in the

 

augmenting table vcxMonitoredEndpointStatisticsTable.

 

A value of zero disables running average statistics for the

 

given row.
