## I have a aggregation as

## GET /ats/\_search { "size": 0, "aggs": { "accessTimes": { "date\_histogram": { "field": "accessTime", "interval": "hour" }, "aggs": { "hit\_docs": { "filter": { "terms": { "cacheResult": ["tcp\_mem\_hit","tcp\_hit","tcp\_refresh\_hit"] } ....

## And the response is

## { .... "aggregations": { "accessTimes": { "buckets": [ { "key\_as\_string": "2015-02-19T11:00:00.000Z", "key": 1424343600000, "doc\_count": 14, "hit\_docs": { "doc\_count": 13 } }, { "key\_as\_string": "2015-02-19T12:00:00.000Z", "key": 1424347200000, "doc\_count": 52, "hit\_docs": { "doc\_count": 41 } }, { "key\_as\_string": "2015-02-19T13:00:00.000Z", "key": 1424350800000, "doc\_count": 231, "hit\_docs": { "doc\_count": 136 } }, { "key\_as\_string": "2015-02-19T14:00:00.000Z", "key": 1424354400000, "doc\_count": 13161, "hit\_docs": { "doc\_count": 8957 } }, { "key\_as\_string": "2015-02-19T15:00:00.000Z", "key": 1424358000000, "doc\_count": 8971, "hit\_docs": { "doc\_count": 5631 } ...

I want to know whether there is some way to access the field of  
_aggregations.buckets.doc\_count_ and a\*ggregations.buckets.hit\_docs.doc\_count  
\*and calculate the hit ration from these two values. Finally, I want to  
view it from kiban4.

Thanks,  
Cong
