}

Now try to fetch hourly count but getting equal count(15) in each bucket, i need only those count related to that date (i.t)

"size": 0,  
"aggs": {  
"final\_bucket": {  
"filter": {  
"term": {  
"zid": "1171533212255571"  
}  
},  
"aggs": {  
"group\_by\_field1": {  
"date\_histogram": {  
"field": "i.t",  
"interval": "hour",  
"min\_doc\_count": 1,  
"format": "yyyy-MM-dd hh:mm a",  
"order" : { "\_key" : "asc" }  
},  
"aggs": {  
"field\_count": {  
"cardinality": {  
"field": "i.ap"  
}  
}  
}  
}  
}  
}  
}
