Hi team,

I want to output the "value":"37" of the query result inside the "Metric" Kibana visualization.

Query-

> POST index-a/\_search?size=0  
> {  
> "aggs" : {  
> "1" : {  
> "cardinality" : {  
> "script" : {  
> "source" : "doc['Service.keyword'].value + '#' + doc['host.name.keyword'].value"  
> }  
> }  
> }  
> }  
> }

The output is -

{  
"took" : 1626,  
"timed\_out" : false,  
"\_shards" : {  
"total" : 6,  
"successful" : 6,  
"skipped" : 0,  
"failed" : 0  
},  
"hits" : {  
"total" : 1821103,  
"max\_score" : 0.0,  
"hits" :   
},  
"aggregations" : {  
"1" : {  
"value" : 37  
}  
}  
}

Is there anyway I could do it in any Kibana visual if not in Metric?

Thanks,  
Darshan

The most supported way is to edit your Kibana index pattern and create a scripted field, which can then be used in most visualizations in Kibana.
