@Christian_Dahlqvist someone do this,

filter {
split {
    field  => "results"
}
split {
    field  => "[results][series]"
}
split {
    field  => "[results][series][values]"
	
	
}
if[name]== "cpu"
{
	ruby 
	{

	 #event.set(event.get("[results][series][columns][0]"),event.get("[results][series][values][0])")
	  code => '
				
				 event.set(event.get("[results][series][columns][0]"),event.get("[results][series][values][0]"))
	
  '

	}
}

any idea?
