Hi, try this:

var theVU_id = context.currentVU.id;
var theVU_name = context.currentVU.name;
var theVU_pop = context.currentVU.getPopulationName();

var theLG_id = context.currentLG.id;
var theLG_name = context.currentLG.name;
var theLG_zone = context.currentLG.getZoneName();

logger.debug("\n\n theVU_vu_id=\t"+theVU_id+"\n theVU_name=\t"+theVU_name+"\n theVU_pop=\t"+theVU_pop+"\n theLG_lg_id=\t"+theLG_id+"\n theLG_name=\t"+theLG_name+"\n theLG_zone=\t"+theLG_zone);

...the vu_name is the script name
