Hello All,

I would like to apply Alias on field

Below is elastic search mapping document script

"logruntime": {  
"type": "date",  
"format": "epoch\_millis||MM/dd/yyyy HH:mm"  
}

So it will create column into Kibana and name of column will be **"logruntime"** , But what if i would name of column **"Server Log Runtime"** into kibana

Do i need to make changes into Elastic Search mapping document ?

Thanks for your help in Advance  
SAM

There is no such thing as a field alias in ES.
