GroupingProduceGroupMainAlertHook - script include not working as expected

[sgchandran]

Hi , 

I have referred the documentation :

 https://www.servicenow.com/docs/r/it-operations-management/event-management/alert-group-use-cases.ht...

and configured the script accordingly in a way to return the oldest alert created as main alert for tag based clustering , but still its not accepting my change as grouping logic and following tag based clustering's grouping logic that is 

alert 1 

alert 2 

alert 3 (created on its own and alert 1 ,2 will become 3's child)

below is the script i used :

var GroupingProduceGroupMainAlertHook = Class.create();

GroupingProduceGroupMainAlertHook.prototype = {

    initialize: function() {},

    getMainAlert: function(groupAlertIDs) {

              if (!groupAlertIDs) {

            return null;

        }

        var gr = new GlideRecord('em_alert');

        gr.addQuery('sys_id', 'IN', groupAlertIDs);

        gr.orderBy('sys_created_on'); // oldest first

        gr.setLimit( 1 );

        gr.query();

        if (gr.next()) {

            return gr;

        }

        return null;

    },

    type: 'GroupingProduceGroupMainAlertHook'

};

Hi @sgchandran 

Return the alert's sys_id string instead of the full GlideRecord object.

When getMainAlert receives an object, the platform ignores it and falls back to its default tag-based clustering logic.

• Before: return gr; (GlideRecord)
• After: return grAlert.getValue('sys_id'); (String)

var GroupingProduceGroupMainAlertHook = Class.create();
GroupingProduceGroupMainAlertHook.prototype = {
initialize: function() {},

getMainAlert: function(groupAlertIDs) {
var alertSysId = "";
var grAlert = null;

return !groupAlertIDs ? "" : (function() {
grAlert = new GlideRecord('em_alert');
grAlert.addQuery('sys_id', 'IN', groupAlertIDs);
grAlert.orderBy('sys_created_on');
grAlert.setLimit(1);
grAlert.query();

return grAlert.next() ? grAlert.getValue('sys_id') : "";
})();
},

type: 'GroupingProduceGroupMainAlertHook'
};
