A little Cisco IOS Embedded Event Manager (EEM) script example

Here is a little script to retrieve and store the output of command periodically on your cisco router. It can be usefull when logs don't want to speak.

conf t
!
event manager session cli username <myusername>
event manager applet MyScriptLogs
event timer watchdog name MyScriptLogs time <mytimer>
action 1 cli command “en"
action 2 cli command “show clock | append bootflash:MyScriptLogs"
action 3 cli command "show policy-map interface | append bootflash:MyScriptLogs"
!
End

Where <myusername> is an user who has privileges to execute the following commands and <mytimer> is the time in seconds between each instance of the script.

Note : you can add many commands to this script with 'action X cli command'.
