Event Processing for Service Quality Events During High CPU Utilization
During periods of high CPU utilization, Operations Manager limits the number of service quality events that it processes. When this occurs, a message appears when you open the Fault Monitor display. The message states that event processing is being controlled.
The excess Service Quality events are written to the NMSROOT\logs\itemlogs\SQTraps\Traps.log file, and these events:
•
Do not appear on the Fault Monitor display.
•
Are not stored in the events history database—They do not appear in Service Quality History reports.
Note
NMSROOT is the directory where Operations Manager is installed on your system. If you selected the default directory during installation, it can be entered as "C:\Program Files\CSCOpx" or C:\PROGRA~1\CSCOpx.
Operations Manager checks CPU utilization on its server every 60 seconds. When CPU utilization reaches and remains at 50% or greater for two minutes, Operations Manager limits the number of service quality events processed until utilization drops below 50%. Table 6-6 lists the number of events that Operations Manager processes.

For more details on how service quality events are grouped, or aggregated, in Fault Monitor, see Service Quality Events Aggregation.
Service Quality Events Aggregation
In Operations Manager, individual service quality (SQ) events are grouped together, or aggregated, based on their threshold criteria settings. service quality event aggregation is completed for registered device pool and Communication Manager Express (CME) devices only.
The aggregated events are displayed in the Fault Monitor. For details on viewing these events in Fault Monitor, see Getting Device and Event Details, page 4-22.
If a service quality event from a phone is not registered with a device pool or Unified CM Express devices, then that event is not aggregated. Such events are displayed as individual events in Fault Monitor window.
For details on service quality event aggregation, see Handling Service Quality Events for Unified CM Express and Device Pools.
Handling Service Quality Events for Unified CM Express and Device Pools
Voice service quality events for Unified CM Express devices and device pools, are now aggregated before they are reported in Operations Manager. Instead of reporting individual service quality events, these events are now aggregated based on criteria set by the device thresholds.
You can use the default device or device pool thresholds or customize them. Aggregation of service quality events is performed for Unified CM Express devices or device pools only.
After you set your Unified CM Express or device pool service quality threshold in the Phone Unregistration Default % field, if the number of events cause the percentage you set to be exceeded then a ServiceQualityThresholdCrossed event is sent.
The calculation to determine whether the threshold has exceeded is through the registered phone count at that point of time in the device pool or Unified CM Express.
For more details, see the Viewing and Editing Device Pool Thresholds, page 19-36.
Note
One cluster can have multiple device pools. Device pools are displayed after you perform a cluster discovery.
Device Pool Example
For example, if there are 100 registered phones in a Unified CM Express device pool named 1DP and the threshold value of that device pool is set to 10%, when 10% of those 100 registered phones experience service quality events (ten service quality events generated on individual phones registered to 1DP), then one aggregated event is generated.
Each incoming event on an individual phone of 1DP increases the count of impacted endpoints for 1DP increments by one. When that count reaches 10, an aggregated event is generated.
When the threshold goes below your set threshold value (for this example below 10) the same aggregated event is cleared. The service quality event is removed from the count when a Clear is generated for phones that were impacted.
All service quality events have a life span of four hours; after four hours the events get cleared. As the events are cleared, the impacted endpoint value is also decreased. When it goes below 10, an aggregated clear event is generated.
If the phone that sent the event belongs to the device pool, you can use the Device Pool Threshold window to view or edit the threshold percentages for the Unified CM Express or device pool. See Viewing and Editing Device Pool Thresholds, page 19-36 for details on customizing device pool thresholds.
The component for an aggregated event is a device pool (if the event is raised on a device pool) or a Unified CM Express (if the event is raised on a CME). Endpoints experiencing issues is the value set by the user which impacts the phone.
All events of Device Pools and CME are listed in the Fault Monitor window. If a SQ event, which is coming from a phone, is not a Device Pool or a CME, that event will not be considered for any aggregation.
Voice Gateways and Unity do not belong to any device pool or CME. So these events are listed as individual events in Fault Monitor.
