Как рассчитать общее количество сегментов, значение которых больше 0?

У меня есть этот запрос, который вычисляет количество событий на ведро. Как рассчитать общее количество сегментов, у которых value больше, чем 0?

GET myindex/_search?
{
  "size": 0,
  "query": {
    "bool": {
      "must": [
        {
          "match": {
            "PlateNumber": "111"
          }
        }
      ]
    }
  },
  "aggs": {
    "daily_intensity": {
      "date_histogram": {
        "field": "Datetime",
        "interval": "day"
      },
      "aggs": {
        "count_of_events": {
          "value_count": {
            "field": "Monthday"
          }
        }
      }
    }
  }
}

Это результат, который я получаю. Ожидаемый ответ, который я хочу получить, — 26, потому что в корзинах всего 26 элементов, у которых value больше 0. По сути, мне не нужны выходные данные всех корзин, мне нужно только это общее число.
