Chapter33 Configuring Embedde d Ev ent Manager Understanding Embedded Event Manager
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 en tere d thro ugh the CL I.
•GOLD event detector– Publishes an event when a GOLD f ailure e vent is detected o n a specif ied card
and subcard.
•Counter event detector–Publishes an event when a named counter crosses a specified threshold.
•Interface counter event detector– Publishes an event when a generic Cisco I OS inter face counte r for
a specified interface crosses a defined threshold. A threshold can be specified as an absolute value
or an incremental value.For example, if the incremental value is set to 50 an event would be
published when the interface counter increases by 50.
•None event detector– Publishes an event when the event manager run CLI command executes an
EEM policy. EEM schedules and runs policies on the basis on an event specification within the
policy itself. An EEM policy must be manually identified and registered before the event manager
run command executes.
•Online insertion and removal event detector–Publishes an event when a hardware insertion or
removal (OIR) event occurs.
•Resource threshold event detector– Generates policies based on global platform values and
thresholds. Includes resources such as CPU utilization and remaining buffer capacity. Applies only
to the master switch.
•SNMP event detector– Allows a standard SNMP MIB object to be monitored and an event to be
generated when the object matches specified values or crosses specified thresholds.
•Syslog event detector– Allows for screening syslog messages for a regular expression pattern match.
The selected messages can be further qualified, requiring that a specific number of occurrences be
logged within a specified time. A match on a specified event criteria triggers a configured policy
action.
•Timer event detector
Publishes events for these timers:
–
An absolute-time-of-day timer publishes an event when a specified absolute date and time
occurs.
–
A countdown timer publishes an event when a timer counts down to zero.
–
A watchdog timer publishes an event when a timer counts down to zero. The timer automatically
resets itself to its initial value and starts to count down again.
–
A CRON timer publishes an event by using a UNIX standard CRON specification to define
when the event is to be published. A CRON timer never publishes events more than once per
minute.
•Watchdog event detector (IOSWDSysMon). This detector applies only to the master switch.
Publishes an event when one of these events occurs:
–
CPU utilization for a Cisco IOS process crosses a threshold.
–
Memory utilization for a Cisco IOS process crosses a threshold.
Two events can be monitored at the same ti me, an d the e v ent publi shing criter ia requ ires that one or
both events cross their specified thresholds.
