I would like to know if anyone wrote an EEM script to trigger the high utilization(either in or out) interface.
for example:
if serial1/0 is (inbound or outbound) is 90% utilization, then do "show ip flow top-talker".

Hi,
Here is an example of a policy that will run every 30 seconds look at the output bps and apply a shaped rate to the interface (gig0/0 in this example) that is twice the measured rate. You can modify it as per your needs.
event manager environment qos_intf gig0/0
event manager environment firstrun 0
event manager applet qos
event timer watchdog time 30
action 001 if $firstrun eq 0
action 002 set prate "0"
action 003 context save key previousrate variable "prate"
action 010 cli command "enable"
action 012 cli command "conf t"
action 013 cli command "event manager environment firstrun 1"
action 014 cli command "end"
action 015 end
action 016 cli command "enable"
action 020 cli command "show int $qos_intf | inc output rate"
action 040 regexp "([0-9]+) bits" "$_cli_result" match rate
action 060 context retrieve key previousrate variable "prate"
action 065 cli command "conf t"
action 070 if $rate ne prate
action 075 multiply $rate 2
action 080 cli command "policy-map shaper"
action 090 cli command "class class-default"
action 100 cli command "shape average $rate"
action 110 cli command "interface $qos_intf"
action 120 cli command "service-policy out shaper"
action 150 syslog msg "Shaper on $qos_intf changed from $prate to $rate bps"
action 160 set prate "$rate"
action 170 context save key previousrate variable "prate"
action 200 end
event manager applet setfirstrun
event syslog pattern "SYS-5-RESTART"
action 010 cli command "enable"
action 020 cli command "conf t"
action 030 cli command "event manager environment firstrun 0"

Thank you.
action 040 regexp "([0-9]+) bits" "$_cli_result" match rate
Can you please explain what is "$_cli_result" value from ?
