Cumulative sum query inside nested term aggregation > avg aggregation

[vinay_srinivas]

Hi,

I want to calculate cumulative sum inside nested term aggregation with avg aggregation.

Document:
{
"_index" : "storagemetric",
"_type" : "metric",
"_id" : "OwjM32oBFWuNUT6ZDzMS",
"_score" : 1.0,
"_source" : {
"subscriberId" : 22222,
"createdTimestamp" : 1555976400000,
"name" : "zzz",
"metricId" : null,
"accountID" : "326952836038",
"cloudType" : "aws",
"attributes" : {
"all_bssize_average_bytes" : 11864.0,
"numberofobjects_average_count" : 3.0
},
"ts" : null
}
}

Response:

{
"key_as_string" : "1553299200000",
"key" : 1553299200000,
"doc_count" : 2,
"genres" : {
"doc_count_error_upper_bound" : 0,
"sum_other_doc_count" : 0,
"buckets" : [
{
"key" : "zzz",
"doc_count" : 1,
"the_avg" : {
"value" : 11864.0
}
},
{
"key" : "aaaaa",
"doc_count" : 1,
"the_avg" : {
"value" : 11864.0
}
}
]
}
}

Query until nested term aggregation with avg:
POST storagemetric/metric/_search

"size": 0,
"aggs": {
"time-filter": {
"filter": {
"range": {
"createdTimestamp": {

}
}
},

              }
            }
