Network Events are entities that represent the various happenings in the network devices. Events can convey either any general information or the current status of the devices in a network. An operator/user can know the history of a device by browsing through the Network Events view in the Web Client.
To view the Network Events view
Click the Fault Management module tab in the Web Client.
On performing this, the Network Events view is displayed on the right-side frame in a table format. This table format is called Events List View. On clicking the Fault Management module tab, the Fault Management tree is displayed on the left-side frame which displays Events and Alarms as its nodes.

By default, the events in the Events List View are displayed in the order of precedence based on the Date/Time and Event ID and in descending order. Events are assigned IDs and these are based on the date and time they are generated. Hence these two properties are interrelated. This order can be changed using the Sorting option.
To sort events
In the Events List View, click the column header.
When you click the column header for the first time, the column is sorted in ascending order. Clicking the same column header again sorts the column in descending order. and represents ascending and descending order respectively.
For example, if you need to sort the events based on its status, click the Status column header. This sorts the events based on its status and the default order of precedence is Critical, Major, Minor, Warning, Clear, and info. For descending order of the same column, click the Status column header again.
The search option in Web Client facilitates searching for one or more events. The search operation is performed on the entire database and is not restricted to the displayed view alone. You can search for a required event based on a general condition or a unique criteria.
To search for event(s)
In the Events list view, click Search. The Advanced Search page is displayed.
Select Match any of the Following option if you want to perform a search operation that satisfies any of the matching criteria that you specify. If you need all the matching criteria to be satisfied for your search operation, select Match all of the Following option.
In the Properties field, select the property based on which you need to perform your search.
If you have selected property related to date or time, the Date Input Helper option comes handy.
On performing this, the Value text field is set with the selected date and time. To modify the date or time, click the Date Input Helper option again and follow steps 1 to 5 as explained above.
In the Conditions field, select the condition based on which you need to restrict your search.
In the Value text field, enter the exact information you are looking for. For example, if you have selected severity in the Properties combo box, then you need to specify the severity value here, say critical, major, etc.
To specify additional criteria, click More and repeat steps 3 to 5. Fewer option can be used to remove the criteria that were last added.

After customization, you can use the print option to get a printed version of the Events List View.
Viewing Related Alarms
Events are converted to alarms based on their significance which are messages that require administrator's/operator's attention. From the Events view, you can view the alarm that has been created for an event.

In the Events List View, select the check box of the desired event. To view related alarms for more than one event, select multiple check boxes.

For more information on Alarms view, refer to Working with Alarms topic.
Working with Event Views
The events in the Events List View could be numerous and hence difficulty arises in identifying events of your interest. A Search can be performed to locate the events you are looking for. But if you are looking for a lot of events that satisfy a certain set of criteria, then use the Add Child View, Modify View Criteria, and Remove View options. This helps you in getting the events of your interest alone in that view, instead of doing a search every time.
A Child View that you create is a subset of data that satisfy a given criteria from a larger collection. By creating new views, you will easily filter the desired data that is displayed, and sort through large amount of events data.
Adding a New View
You can add/create a new view by specifying various criteria and providing a name for the view. The views you create enable you to quickly monitor the devices of your concern. Multiple views can also be created to display a variety of information.
For example, you can create a new view named MasterEvents which shows only events in a particular network. Within this MasterEvents view, you can create more views, say ME1, ME2, etc. ME1 can have a different set of criteria, say only critical events in that particular network. Deleting MasterEvents deletes its child views (ME1, ME2, etc.) as well.
To add a view
In the Events List View, click Add Child View. The options to create the view are displayed.
Enter the view's name in Custom view name field. This is a mandatory field.

Wildcard characters can be used to specify the matching criteria. For information on the wildcard characters that can be used, refer to Tips and Tricks in Appendix. If none of the fields is filled in (except for Custom view name), then by default all the fields are set with the value 'all'.
On configuring the criteria, click Submit.
On performing this, a new child node with the configured view name is created under Fault Management > Network Events tree node. Following the same procedure, more custom views can be created.
Modifying a View
A view can be modified to change the criteria that were set or to rename the view.
To modify a view
In the Events List View, click the desired view on the Fault Management > Network Events tree.

On performing this, the view is refreshed to provide you the new view based on modified criteria.
