group alerts if there are 3 alerts if not dont group them

[AnimeshP_96]

requirement is if 3 alerts is created in servicenow , group them which is working but now what is happening is 3 alerts are created but this rule is not matching and showing some different rule in activites under work notes ,some other rule is taking precendence. ..so now if 4 alerts re created it should not group it 

(function findCorrelatedAlerts(currentAlert) {

    var result = {};

    var table = "em_alert";

    //var cnt;

    var storeID = [];

    //var childalerts = [];

    var parent = [];

    var alertGr = new GlideRecord(table);

    alertGr.addNullQuery("parent");

    alertGr.orderBy("sys_created_on");

    alertGr.setLimit(3);

    alertGr.query();

    while (alertGr.next()) {

        gs.info("this is li3ne 13 from me");

        storeID.push(alertGr.getUniqueValue());

    }

    if (storeID.length === 3) {

        gs.info("this is2222229833 ");

        parent = currentAlert.sys_id;

    }

    gs.info("this is2379863 " + parent);

    result = {

        'parent': [String(currentAlert.sys_id)]

    };

    return JSON.stringify(result);

})(currentAlert);

pls can someone help me where i am going wrong..

in the below picture it is creating a new alert instead of making 607 as parent which is expected

Hi @AnimeshP_96 ,

logic

(function findCorrelatedAlerts(currentAlert) {

var groupByField1 = currentAlert.resource;
var groupByField2 = currentAlert.metric_name;

var groupCondition = new GlideRecord('em_alert');

groupCondition.addQuery('resource', groupByField1);
groupCondition.addQuery('metric_name', groupByField2);

groupCondition.addNullQuery('parent');

groupCondition.addQuery('sys_id', '!=', currentAlert.sys_id);

groupCondition.query();

var existingAlerts = [];
while (groupCondition.next()) {
existingAlerts.push(String(groupCondition.getUniqueValue()));
}

if (existingAlerts.length === 2) {

gs.info("Custom 3-Alert Rule: SUCCESS. Grouping " + existingAlerts.length + " alerts under Parent: " + currentAlert.number);

return JSON.stringify({
'parent': existingAlerts
});

} else {

gs.info("Custom 3-Alert Rule: FAILURE. Found " + existingAlerts.length + " matching ungrouped alerts. Requires exactly 2 for grouping.");

return JSON.stringify({
'parent': []
});
}

})(currentAlert);

what debugging did you do?

so first log :   gs.info("this is li3ne 13 from me");  this is printed 6 times in log table but it should be 3 becuase setlimit(3) is provided in the script
