// How can i get the first 5 values from the data

});

I've edited out all references to JSON. There's no JSON in your question. — Álvaro González

you can use the slice method

var first5 = server.slice(0,5)

array.slice(begin[, end])

server.slice(0,5)

Use a for loop:

for (var i = 0; i < 5; i++) {
   var obj = server[i];

   // Do something...
   // obj.jobid, obj.browser, etc.
}

Of if you're using jQuery:

$.getJSON('/api/Controller/Action', {}, function (result) {
    $.each(result, function (i, v) {
        if (i > 4) return false; // Stop processing after 5 entries

        // 'v' now is your current object
        // v.jobid, v.browser, etc.
    });
});

for(j=0;j<server.length;j++){
    var elms = server[j];
    for(i=0;i<elms.length;i++){
         if(i<4){
             console.log(elms[i].jobid); //etc
          }else{
       break;
      }
    }

I think it should be .each() and not .forEach()

server.each(function (index,result) {
  if(index<5){
   //do stuff;
  //array.push(item);
  }     
});

Try this code, i guess that this is what you need,

$(document).ready(function() {
    $.each(server, function(index, item) {
                if(index < 5) {
                    //DoSomeThings
                } else {
                    return;
                }
            });
       });
