    Element Type

    The element associated with the event; for example, Interface, Tunnel, VPN.

    The name of the element. For example, if the element type is Interface, the element name might be ge-0/0/3.0.


    The severity of the event can be INFO, UP, WARNING, MINOR, MAJOR, CRITICAL, or DOWN. These are automatically set by default for each event, but can also be customized.


    The time the event occurred, using the server’s time zone. For aggregate events, this is the time the most recent event occurred.

    First Timestamp

    For aggregate events only, the timestamp of the first event in the aggregated events.


    For aggregate events only, the number of events included in the aggregate event.

    Source IP

    The IP address of the device sending the event.

    Note that the number of rows in the events table cannot be the same as the number of events due to aggregation of events. Events that share the same Event Type, Device ID, Element Type, and Element Name are grouped together into one row representing an aggregate event in order to reduce clutter in the Event Browser.
