如何在elasticsearch中查询到索引的字节大小？

from elasticsearch import Elasticsearch

# 连接elasticsearch集群
es = Elasticsearch(hosts=['localhost'])

# 获取所有索引的信息
indices_info = es.cat.indices(format='json')

# 遍历索引列表，找到目标索引
target_index = None
for index_info in indices_info:
    if index_info['index'] == 'your_index_name':
        target_index = index_info
        break

# 如果找到了目标索引
if target_index:
    # 获取目标索引的统计信息
    index_stats = es.indices.stats(index='your_index_name')

    # 提取索引的字节大小
    byte_size = index_stats['indices']['your_index_name']['total']['store']['size_in_bytes']

    print(f"The byte size of index 'your_index_name' is: {byte_size}")
else:
    print("Index 'your_index_name' not found.")
