基于自定义桶的elasticsearch百分位聚合

我不明白有没有可能在elasticsearch中根据自定义存储桶的值计算百分位数?例如,我有一个bucket列表:

{"@timestamp": "2019-10-04T17:27:50.228Z", "name": "http_server_requests_histogram","method": "GET","outcome": "SUCCESS","status": "200","uri": "/employee/{id}","le": "10", "value": 1}
{"@timestamp": "2019-10-04T17:27:50.228Z","name": "http_server_requests_histogram","method": "GET","outcome": "SUCCESS","status": "200","uri": "/employee/{id}","le": "50", "value": 2}
{"@timestamp": "2019-10-04T17:27:50.228Z", "name": "http_server_requests_histogram","method": "GET","outcome": "SUCCESS","status": "200","uri": "/employee/{id}","le": "100", "value": 7}
{"@timestamp": "2019-10-04T17:27:50.228Z","name": "http_server_requests_histogram","method": "GET","outcome": "SUCCESS","status": "200","uri": "/employee/{id}","le": "500", "value": 125}
{"@timestamp": "2019-10-04T17:27:50.228Z","name": "http_server_requests_histogram","method": "GET","outcome": "SUCCESS","status": "200","uri": "/employee/{id}","le": "1000", "value": 1}

{"@timestamp": "2019-10-04T17:28:05.228Z", "name": "http_server_requests_histogram","method": "GET","outcome": "SUCCESS","status": "200","uri": "/employee/{id}","le": "10", "value": 0}
{"@timestamp": "2019-10-04T17:28:05.228Z","name": "http_server_requests_histogram","method": "GET","outcome": "SUCCESS","status": "200","uri": "/employee/{id}","le": "50", "value": 1}
{"@timestamp": "2019-10-04T17:28:05.228Z", "name": "http_server_requests_histogram","method": "GET","outcome": "SUCCESS","status": "200","uri": "/employee/{id}","le": "100", "value": 3}
{"@timestamp": "2019-10-04T17:28:05.228Z","name": "http_server_requests_histogram","method": "GET","outcome": "SUCCESS","status": "200","uri": "/employee/{id}","le": "500", "value": 134}
{"@timestamp": "2019-10-04T17:28:05.228Z","name": "http_server_requests_histogram","method": "GET","outcome": "SUCCESS","status": "200","uri": "/employee/{id}","le": "1000", "value": 2}

哪里 le 它是一些(请求/函数执行)持续时间和 value 执行的请求数小于或等于某个值(从10ms到1000ms)。根据这些桶,我需要计算百分位。在普罗米修斯,我们可以通过分位数。elasticsearch是否允许使用smth?这是问题的重复,但我没有找到答案。
