Hi, do you have any idea how i can remove empty buckets from my response?  
My query looks like that:

```
GET kubernetes-prod-metrics/_search
{
  "_source": [
    "@timestamp",
    "kubernetes.namespace",
    "kubernetes.container.name",
    "kubernetes.pod.name",
    "kubernetes.container.status.restarts",
    "metricset.module",
    "metricset.name"
  ],
  "query": {
    "bool": {
      "must": [
        {
          "range": {
            "@timestamp": {
              "gte": "now/m-60m",
              "lt": "now/m-1m"
            }
          }
        }
      ],
      "filter": [
        {
          "term": {
            "metricset.module": "kubernetes"
          }
        },
        {
          "term": {
            "kubernetes.namespace": "ccsm-prod"
          }
        },
        {
          "term": {
            "metricset.name": "state_container"
          }
        },
        {
          "exists": {
            "field": "kubernetes.container.status.restarts"
          }
        }
      ]
    }
  },
  "size": 0,
  "aggs": {
    "pod": {
      "terms": {
        "field": "kubernetes.pod.name",
        "size": 100
      },
      "aggs": {
        "container": {
          "terms": {
            "field": "kubernetes.container.name",
            "size": 100
          },
          "aggs": {
            "min": {
              "min": {
                "field": "kubernetes.container.status.restarts"
              }
            },
            "max": {
              "max": {
                "field": "kubernetes.container.status.restarts"
              }
            },
            "result": {
              "bucket_script": {
                "buckets_path": {
                  "min": "min",
                  "max": "max"
                },
                "script": "params.max-params.min"
              }
            },
            "restart": {
              "bucket_selector": {
                "buckets_path": {
                  "result": "result"
                },
                "script": "params.result>0"
              }
            }
          }
        }
      }
    }
  }
}

```

and this is the result:

```
{
  "took" : 1421,
  "timed_out" : false,
  "_shards" : {
    "total" : 126,
    "successful" : 126,
    "skipped" : 0,
    "failed" : 0
  },
  "hits" : {
    "total" : {
      "value" : 3363,
      "relation" : "eq"
    },
    "max_score" : null,
    "hits" : []
  },
  "aggregations" : {
    "pod" : {
      "doc_count_error_upper_bound" : 0,
      "sum_other_doc_count" : 0,
      "buckets" : [
       {
      "key" : "ccsm-api-585dcb79d5-8gscr",
      "doc_count" : 59,
      "container" : {
        "doc_count_error_upper_bound" : 0,
        "sum_other_doc_count" : 0,
        "buckets" : []
      }
    },
    {
      "key" : "ccsm-api-585dcb79d5-dkjbx",
      "doc_count" : 59,
      "container" : {
        "doc_count_error_upper_bound" : 0,
        "sum_other_doc_count" : 0,
        "buckets" : []
      }
    },
    {
      "key" : "ccsm-adapter-8485496bcd-8ctzq",
      "doc_count" : 59,
      "container" : {
        "doc_count_error_upper_bound" : 0,
        "sum_other_doc_count" : 0,
        "buckets" : []
      }
    },
         ...
    }
}
}

```

if the condition (in bucket selector) is true, it looks :

```
{
  "took" : 202,
  "timed_out" : false,
  "_shards" : {
    "total" : 126,
    "successful" : 126,
    "skipped" : 0,
    "failed" : 0
  },
  "hits" : {
    "total" : {
      "value" : 3363,
      "relation" : "eq"
    },
    "max_score" : null,
    "hits" : []
  },
  "aggregations" : {
    "pod" : {
      "doc_count_error_upper_bound" : 0,
      "sum_other_doc_count" : 0,
      "buckets" : [
        {
          "key" : "ccsm-api-585dcb79d5-8gscr",
          "doc_count" : 59,
          "container" : {
            "doc_count_error_upper_bound" : 0,
            "sum_other_doc_count" : 0,
            "buckets" : [
              {
                "key" : "ccsm-api",
                "doc_count" : 59,
                "min" : {
                  "value" : 0.0
                },
                "max" : {
                  "value" : 0.0
                },
                "result" : {
                  "value" : 0.0
                }
              }
            ]
          }
        },
        {
          "key" : "ccsm-api-585dcb79d5-dkjbx",
          "doc_count" : 59,
          "container" : {
            "doc_count_error_upper_bound" : 0,
            "sum_other_doc_count" : 0,
            "buckets" : [
              {
                "key" : "ccsm-api",
                "doc_count" : 59,
                "min" : {
                  "value" : 1.0
                },
                "max" : {
                  "value" : 1.0
                },
                "result" : {
                  "value" : 0.0
                }
              }
            ]
          }
        },
        {
          "key" : "ccsm-adapter-8485496bcd-8ctzq",
          "doc_count" : 59,
          "container" : {
            "doc_count_error_upper_bound" : 0,
            "sum_other_doc_count" : 0,
            "buckets" : [
              {
                "key" : "ccsm-adapter",
                "doc_count" : 59,
                "min" : {
                  "value" : 0.0
                },
                "max" : {
                  "value" : 0.0
                },
                "result" : {
                  "value" : 0.0
                }
              }
            ]
          }
        },
         ...
}
}
}

```

I would like to get aggregations.pod.buckets,length() and use it in condition of alarm if there is any restarting container, so i need to remove empty container.buckets. Do you have any idea how to do that?
