Simple Logger Event Throttling
Simple event throttling provides a mechanism to protect event receivers from being
overloaded when a scenario causes many events to be generated in a very short period of time.
A throttling rate (events/seconds), can be configured. Specific application events can be
configured to be throttled. Once the throttling event limit is exceeded in a throttling interval,
any further events of that type are dropped and the dropped events counter is incremented.
Dropped events counts are displayed with the
show>log>event-control
command.
Events are dropped before being sent to one of the logger event collector tasks. There is no
record of the details of the dropped events and therefore no way to retrieve event history data
lost by this throttling method.
A particular event type can be generated by multiple managed objects within the system. At
the point that this throttling method is applied, the logger application has no information
about the managed object that generated the event and cannot distinguish between events
generated by object “A” from events generated by object “B”. If the events have the same
event-id, they are throttled regardless of the managed object that generated them. The logger
application also cannot distinguish between events that will be logged to destination log-id
<n> from events that will be logged to destination log-id <m>.
<severity>
The severity level name of the event
CLEARED — a cleared event (severity number 1)
INFO — an indeterminate/informational severity event (severity
level 2)
CRITICAL — a critical severity event (severity level 3)
MAJOR — a major severity event (severity level 4)
MINOR — a minor severity event (severity level 5)
WARNING — a warning severity event (severity 6)
<application>
The application generating the log message
<event_id>
The application’s event ID number for the event
<router>
The router name representing the VRF-ID that generated the
event
<subject>
The subject/affected object for the event
<description>
A text description of the event
