Using the Network Events Display
The Network Events screen displays configured events received from network devices and provides basic event information (for example, severity, date/time received).
To access the Network Events screen, click on Diagnostic Tools > Network Events and select the Events tab under the “Monitor” section of the OmniVista Cirrus Menu.
The top section of the Network Events screen provides a summary of event activity during the specified time range based on type of Events. The bottom section of the screen is the Events List, which displays the events received within the specified time range. You can also use the Events list to acknowledge or delete events.
Viewing the Events List
All event notifications from all devices within the Organization scope and specified timeframe are displayed and updated in real-time. As you scroll the the list of events and a new event is received, a “Click here to view new events” message will appear. Click on the message to return to the top of the list to view the new events.
New events received are also indicated when a red blinking dot appears to the top of the bell icon on the Organization banner. For example:
The bell icon provides a list of recent 10 new traps and alerts received. To view the list of traps, click on the bell icon, then on AP Traps. A drop-down window displays the list of new Traps and Alerts.
If you click on See All at the bottom of the drop-down list, the Network Events screen is displayed.
View New Events Notification
When a new event is received, you will get a pop-up which is displayed on the top of the Event List table to indicate that the new trap (AP trap or Switch trap) has been raised as shown below:
The above pop-up displays only when one of the below criteria is matched:
Received trap matches the column filters.
Received trap matches the search filter.
Received trap falls under the selected scope entity.
The time filter is selected other than the custom range (for example, last hour, last 6 hours, etc. ).
Note: The red blinking dot on the top of the bell icon displays whenever a new trap is received, irrespective of the mentioned criteria.
