Event Detectors
EEM software programs known as event detectors determine when an EEM event occurs. Event
detectors are separate systems that provide an interface between the agent being monitored, for example
SNMP, and the EEM polices where an action can be implemented. Event detectors are generated only
by the master switch. CLI and routing processes also run only from the master switch.
Note The stack member switch does not generate events and does not support memory threshold notifications
or IOSWdSysmon event detectors.
EEM allows these event detectors:
• Application-specific event detector– Allows any EEM policy to publish an event.
• IOS CLI event detector– Generates policies based on the commands entered through the CLI.
