Complex rules can be configured to match on log events as a trigger for an EHS handler.
When a log event is generated in SR OS it will be subject to discard via suppression and throttling
(config>log>event-control) before it is evaluated as a trigger for EHS:
•
•
EHS will trigger on log events that are dropped by user configured log filters that are assigned to
individual logs (config>log>filter). The EHS event trigger logic occurs before the distribution of
log event streams into individual logs.
