Configuring Embedded Event Manager
Configuring Embedded Event Manager
EXAMPLE
The following example shows how to configure an EEM applet that runs when there is an exact match on the value of a
specified SNMP object ID that represents the amount of current process memory.
Switch(config-applet)# event snmp oid 1.3.6.1.4.1.9.9.48.1.1.1.6.1 get-type exact entry-op lt entry-val
5120000 poll-interval 10
These examples show actions that are taken in response to an EEM event:
Switch(config-applet)# action 1.0 syslog priority critical msg "Memory exhausted; current available
memory is $_snmp_oid_val bytes"
Switch (config-applet)# action 2.0 force-switchover
