[j-nsp] Need help with event script

[Alexander Shikoff]

Hello!

I'm trying to make changes of run-time configuration based on time of day.
I want simple event script to change policer on interface at given time.
Script is quite simple (see below).
event-options are configured as follows:

[edit event-options]
minotaur at br1-gdr.ki# show 
generate-event {
    Start-Business-Time time-of-day "17:07:00 +0300";
}
policy Modify-Speeds-to-World {
    events Start-Business-Time;
    then {
        event-script change-policer.slax {
            arguments {
                interface ge-0/0/0;
                unit 400;
                policer-in pol-50Mbit;
                policer-out pol-50Mbit;
            }
        }
    }
}
event-script {
    file change-policer.slax;
}
traceoptions {
    file events.log;
    flag events;
    flag server;
    flag policy;
}




The problem is that script does not make any changes in configuration and fails to work:
[edit event-options]
minotaur at br1-gdr.ki# run show log escript.log
[...]
Oct 23 17:07:05 results of event script
Oct 23 17:07:05 begin dump
<output>Changing policers on interface ge-0/0/0 .400 </output>Oct 23 17:07:05 end dump
Oct 23 17:07:05 results of event script
Oct 23 17:07:05 begin dump
<output>

Oct 23 17:07:05 event script processing ends
Oct 23 17:07:07 escriptdefinition script processing begins
Oct 23 17:07:07 escriptdefinition script processing ends

I'm wondering where does trailing whitespace appear from? And is that the main
reason of execution fault?

Any suggestions? Thanks a lot.




 My script:

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";

param $interface;
param $unit;
param $policer-in;
param $policer-out;

match / {
 <event-script-results> {
  <output> 'Changing policers on interface ' _ $interface _ '.' _ $unit;

  var $newcfg = {
        <configuration> {
         <interfaces> {
          <interface> {
           <name> $interface;
           <unit> {
            <name> $unit;
            <family> {
             <inet> {
              <policer> {
               <input> $policer-in;
               <output> $policer-out;
              }
             }
            }
           }
          }
         }
        }
  } /* $newcfg */

  var $rpc = jcs:open();
  var $results := { call jcs:load-configuration($connection=$rpc, $configuration=$newcfg); }

  <output> $results;

  expr jcs:close( $rpc );
 }
}
