我想列出ElasticSearch服务器上的所有索引。我试了一下:
curl -XGET localhost:9200/
但它给了我这个:
{
"ok" : true,
"status" : 200,
"name" : "El Aguila",
"version" : {
"number" : "0.19.3",
"snapshot_build" : false
},
"tagline" : "You Know, for Search"
}
我想要一个所有索引的列表..
当前回答
我还推荐使用/_cat/ indexes，它提供了一个人类可读的索引列表。

Java API
Settings settings = Settings.settingsBuilder().put("cluster.name", Consts.ES_CLUSTER_NAME).build();
TransportClient client = TransportClient.builder().settings(settings).build().addTransportAddress(new InetSocketTransportAddress(InetAddress.getByName("52.43.207.11"), 9300));
IndicesAdminClient indicesAdminClient = client.admin().indices();
GetIndexResponse getIndexResponse = indicesAdminClient.getIndex(new GetIndexRequest()).get();
for (String index : getIndexResponse.getIndices()) {
logger.info("[index:" + index + "]");
}
curl -XGET 'http://localhost:9200/_cluster/health?水平=指数'
这将输出如下所示
{
"cluster_name": "XXXXXX:name",
"status": "green",
"timed_out": false,
"number_of_nodes": 3,
"number_of_data_nodes": 3,
"active_primary_shards": 199,
"active_shards": 398,
"relocating_shards": 0,
"initializing_shards": 0,
"unassigned_shards": 0,
"delayed_unassigned_shards": 0,
"number_of_pending_tasks": 0,
"number_of_in_flight_fetch": 0,
"task_max_waiting_in_queue_millis": 0,
"active_shards_percent_as_number": 100,
"indices": {
"logstash-2017.06.19": {
"status": "green",
"number_of_shards": 3,
"number_of_replicas": 1,
"active_primary_shards": 3,
"active_shards": 6,
"relocating_shards": 0,
"initializing_shards": 0,
"unassigned_shards": 0
},
"logstash-2017.06.18": {
"status": "green",
"number_of_shards": 3,
"number_of_replicas": 1,
"active_primary_shards": 3,
"active_shards": 6,
"relocating_shards": 0,
"initializing_shards": 0,
"unassigned_shards": 0
}}
这里的人已经回答了如何在curl和sense中做到这一点，有些人可能需要在java中这样做。
开始了
client.admin().indices().stats(new IndicesStatsRequest()).actionGet().getIndices().keySet()
对于Elasticsearch 6。X，我发现下面的方法最有帮助。每个响应提供不同的数据。
# more verbose
curl -sS 'localhost:9200/_stats' | jq -C ".indices" | less
# less verbose, summary
curl -sS 'localhost:9200/_cluster/health?level=indices' | jq -C ".indices" | less
您还可以使用获取特定的索引
curl -X GET "localhost:9200/<INDEX_NAME>"
e.g. curl -X GET "localhost:9200/twitter"
You may get output like:
{
"twitter": {
"aliases": {
},
"mappings": {
},
"settings": {
"index": {
"creation_date": "1540797250479",
"number_of_shards": "3",
"number_of_replicas": "2",
"uuid": "CHYecky8Q-ijsoJbpXP95w",
"version": {
"created": "6040299"
},
"provided_name": "twitter"
}
}
}
}
