you're calling event change_pga from alertd but then icall script is expecting change-priority. Align those and you should be good to go.

HI ikkut23:I tested it a little bit The following is my config,It can work normally, for your reference#
cat /config/user_alert.conf
alert server1-down "Pool /Common/TeststanbyNode member /Common/node_10.1.20.13:80 monitor status down." {
   exec command="tmsh generate sys icall event change_pga context { { name ip value node_10.1.20.13 } {name port value 80} }"
}
#
tmsh list sys icall script pool_member1_down
sys icall script pool_member1_down {
    app-service none
    definition {
        foreach var { ip port } {
            set $var $EVENT::context($var)
        }
        tmsh::modify ltm pool TeststanbyNode members modify \{ $ip:$port \{priority-group 20\} \}
    }
    description none
    events none
}
#
tmsh list sys icall handler triggered change_pga
sys icall handler triggered change_pga {
    script pool_member1_down
    subscriptions {
        change_pga {
            event-name change_pga
        }
    }
}have a good day!

ah..two things.&nbsp;

Use tmsh::modify instead of exec, no need to leave the script to modify objects (this is an optimization, not a fix)
Escape your braces:

tmsh::modify ltm pool TeststanbyNode members modify \{ 192.168.18.211:80 \{priority-group 20\}\}

Hi Jason thnx a lot , now i`m getting this error on /var/ltm logs when i execute :

generate sys icall event change_priority

tmsh[19010]: 01420006:3: members: required brace is missing "{"
err scriptd[3868]: 014f0013:3: Script (/Common/pool_member1_down) generated this Tcl error: (script did not successfully complete: (Syntax Error: members: required brace is missing "{"

and when i manually put node down no errors on /var/ltm logs except that pool member monitor is down but no change on priority.

Thnx
