How to Use the Service Quality Alerts Display

Viewing Events Associated with a Service Quality Alert

How to Use the Service Quality Alerts Display

The Service Quality Alerts display provides real-time information about IP phone service quality. Service Quality Alerts displays are designed so that you can set them up and leave them running, providing an ongoing monitoring tool that signals you when something needs attention.

When Operations Manager receives traps from Service Monitor, Operations Manager generates an event or events that are rolled up into an alert. The alert is shown on your Service Quality Alerts display. From a Service Quality Alerts display you can launch other windows to obtain more information, including:

Event details—Displays details for the events that caused the alert to be generated.

Service quality history—Reports service quality events generated during the previous 24 hours.


Note All Service Quality History reports generated from within the Service Quality Alerts display provide information from the past 24 hours. To generate a Service Quality History report on time spans beyond the last 24 hours, use Service Quality History from the Reports tab by selecting Reports > Service Quality History. For more information, see Getting All Stored Information on a Service Quality Event.


Starting the Service Quality Alerts Display

To start the Service Quality Alerts display, select Monitoring Dashboards > Service Quality Alerts. Service Quality Alerts appears in a new window.


Tip After you become familiar with the Service Quality Alerts display, you can filter the information it provides as described in Filtering Service Quality Alerts.


Understanding the Layout of the Service Quality Alerts Display

These topics provide details about the information in the Service Quality Alerts display.

View Pane

The view pane lists the currently available views, or user-defined device groups, available for Service Quality Alerts. By default, the All Alerts view is always shown and cannot be deleted from your Service Quality Alerts display.

The current view is highlighted in the view pane. Alerts for the devices in the current view are shown in the tabular display pane. To select another view, simply click the view name in the view pane.

Icons next to the views indicate the severity of the alerts received from devices in those views, signaling you that the devices may need attention.

For the currently selected view, severity icons also appear next to the alerts in the tabular display to help you quickly locate a specific alert.

The view pane is updated every two minutes. You can have up to 18 views in the view pane in a single Service Quality Alerts display.

Launch Information and View Status Bar Area

The launch information area shows the time on the server when the Service Quality Alerts display was started or when it was last manually refreshed. The view status bar lists the selected view, the number of alerts in that view, and, if filters have been applied, displays "(Filtered.)"

Tabular Display Pane

The tabular display pane is the core of the Service Quality Alerts display. It contains a list of alerts that are occurring on the devices in your current view. This pane is refreshed every 60 seconds. For an explanation for all of the items in the tabular display, see Using the Service Quality Alerts Display.

Icons alert you to what needs attention; for example, the severity icons indicate which views and alerts require attention. The tabular display pane is scrollable and can display up to 1,000 records.

Window Tools Area

The top-right corner of the Service Quality Alerts display contains available tools buttons. All buttons are described in Table 4-1.

Using the Service Quality Alerts Display

The Service Quality Alerts display shows the alerts that are occurring in your current view. Alerts are grouped by their severity: critical, warning, or informational. Within these severity groupings, alerts with the latest change are listed first.

When an alert is generated, it remains in the Service Quality Alerts display until it is cleared. Alerts are cleared every 8 hours; see Configuring Service Quality Event Settings, page 20-8. While the alert is in the display, if any of its events recur, the alert is updated. If an expired alert recurs, a new alert with a new ID is shown. This display is refreshed every 60 seconds.


Tip You can generate a 24-hour Service Quality History report on all events that occurred on devices in your view by clicking the Service Quality Event History button in the upper-right corner of the window.

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. You will know when this is occurring by the message that appears in the view status bar of the Service Quality Alerts display. The message states that not every alert is being displayed. The excess Service Quality Alerts display events are written to the NMSROOT\logs\itemlogs\SQTraps\Traps.log file, and these events:

Do not appear on the Service Quality Alerts display.

Are not stored in the Alerts and 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 is C:\Program Files\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 4-5 lists the number of events that Operations Manager processes.
