Can't add a number type for a field

Hello everyone !

After a update of Kibana, the new feature where we can add a color for number is very important for me and my network team.

But where i want a add a field type number Kibana think it's a string...

My config test :

if [openViewSeverity] == "Major" {
				mutate {
					add_field => {
						"severity" => "critical"
						severity_level_test => 2

Why kibana says severity_level_test is a string not a number ?

Thank you so much for your reply.


Just add a grok patern like this :

  grok {
  	match => {
  		"level_severity" => ["%{INT:number_level_severity2:int}"]
