Notification Plugin
Overview
Notification Plugin helps an operator to pay attention to the most important events. The plugin generates notifications based on events according to specified rules and displays them in the notification panel that appears on the right side of the web page. In addition, the plugin turns on an audible alert depending on the notification type. Download the plugin using the link. The notification panel is shown in the following figure.
The plugin displays only those events that require acknowledgement and have not yet been acknowledged. The filter specified in the plugin configuration is applied to the displayed events. Clicking the Information button displays a tooltip related to the notification. If a user acknowledges the event, the corresponding notification is hidden.
