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.
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.
• Generic Online Diagnostics (GOLD) event detector– Publishes an event when a GOLD failure event
is detected on a specified card and subcard.
• Counter event detector–Publishes an event when a named counter crosses a specified threshold.
