How to test/simulate an event to trigger an event script

instead of waiting for an event to happen you can generate an event using the logger command from the cli.

First you need to get the attribute of the event if you want to pass an argument to the script. Use "help syslog <command>" 
jnpr@router> help syslog UI_CHILD_EXITED    
Name:          UI_CHILD_EXITED
Message:       Child exited: PID <pid>, status <return-value><core-dump-status>, command '<command>'
Help:          Child process of mgd exited

In help syslog the attribute will be displayed inside the <> bracket.
pid, return-value, core-dump-status, and command are the attributes

jnpr@router# show event-options
policy test {
    events ui_child_exited;
    then {
        event-script test.slax {
            arguments {
                mib "{$UI_CHILD_EXITED.pid}";
            output-filename ARG;
            destination local;
destinations {
    local {
        archive-sites {

go into shell as root and then issue the logger command

logger [-e event-id/tag] [-p priority] [-d daemon] [-a attr=value]

root@router% logger -e UI_CHILD_EXITED -a "pid=111" test-syslog-message

jnpr@router# run show log messages

jnpr@router# run file show router_ARG_20090701_065802

root@router> op test.slax mib "111"



root@router% more test.slax
version 1.0;

ns junos = "http://xml.juniper.net/junos/*/junos";
ns xnm = "http://xml.juniper.net/xnm/1.1/xnm";
ns jcs = "http://xml.juniper.net/junos/commit-scripts/1.0";

import "../import/junos.xsl";
var $arguments = <argument> {
    <name> "mib";

param $mib;

match / {
    <op-script-results> {

        <output method = "text"> {

                    expr $mib;
            <xsl:document href = "/var/home/jnpr/text.txt"> {
                copy-of $mib;
