In Cisco IOS, the Embedded Event Manager (EEM) applet can be used to monitor events and take action when a specified event occurs. To send a syslog message, the correct command within an EEM applet is action <sequence-number> syslog msg "<message-text>". This command will trigger a syslog message with the specified text when the applet conditions are met.
