The primary functionality of the Events and Notifications application is to log various events generated in the Crystal Eye appliance on a real time basis. All the event types recorded/logged by Crystal Eye are categorized under three main categories namely, Informational Events, Warning Events and Critical Events. The information generated through these event types can be interpreted to effectively monitor various CE related processes.
The Events and Notifications application has a dedicated table that tracks, records and displays all the events that occurs in the Crystal Eye appliance. This table not just shows the Event Type but also describes it in detail. The screenshot below shows the Events and Notification table. The Description column elaborates on what exactly happened and the Event Type column stresses on the nature of the event. The Timestamp column shows the date and time at which the event occurred.
Note: The list of event types that are tracked and displayed by the events and notification application are Memory OOM Killed, User Logout, User Login, User Authentication Failed, Memory Swap High, System Firewall Panic, System Load High and Failed Login Attempt. The events that occurred in the past 24 hours can also be monitored in the Events – Last 24 Hours widget in the System Dashboard of the Crystal Eye appliance.
One of the most useful features of the Events and Notifications application is that it can be configured to send email notifications of the ongoing CE events to multiple email ids. However, the CE administrator has the choice to set the app to send these notifications on a real-time basis or on a daily basis.

The Events and Notifications application displays all the events in a tabular format with advanced filtering capabilities that can be used to categorize various event types.
One of the major reasons for having events and notifications displayed on a real-time basis is that it facilitates continuous monitoring of various event types that occurs in the Crystal Eye appliance. In-fact these events must just not be monitored but remedial actions must be taken on a timely basis based on the events that has been flagged. The Acknowledge All button is used to acknowledge all events in the table which also leads to the clearance of these events from the alert notification counter at the top-right corner of the page. This mechanism is explained below.
All the events that are displayed in a tabular format in the application are also parallelly populated at the alert notification counter located at the top-right corner of the page (refer to the bell icon in the screenshot below).
How to acknowledge all events in the events and notifications table?
Step 1: In the screenshot below, you will notice that the bell icon (circled in red) has the number 5 mentioned over it. This means that there are 5 events in the table that have not been acknowledged yet by the CE administrator.
Step 2: In the Events and Notification application page, click the Acknowledge All button.
Step 3: You will now see a pop-up. Click the Confirm button.
Note: Once you have hit the confirm button you will notice that the number of alerts mentioned over the bell icon would be erased.
