5.3.6 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>.
