To create a WMI monitor for Failed Qo Srequests, provide host name (it must be a Windows host) and specify custom WQL query:
The number of QoS requests generated by QoS-enabled applications that have been rejected by the RSVP service. Failed QoS requests can be caused by invalid QoS requests.
RSVP service performance counters.
