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
获得一个只有索引的列表的最简单的方法是使用上面的答案，带有'h=index'参数:
curl -XGET "localhost:9200/_cat/indices?h=index"
其他回答
_stats/ indexes给出带有索引的结果。
$ curl -XGET "localhost:9200/_stats/indices?pretty=true"
{
"_shards" : {
"total" : 10,
"successful" : 5,
"failed" : 0
},
"_all" : {
"primaries" : { },
"total" : { }
},
"indices" : {
"visitors" : {
"primaries" : { },
"total" : { }
}
}
}
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
_stats命令提供了通过指定所需指标来自定义结果的方法。要获得索引，查询如下:
GET /_stats/indices
_stats查询的一般格式是:
/_stats
/_stats/{metric}
/_stats/{metric}/{indexMetric}
/{index}/_stats
/{index}/_stats/{metric}
指标在哪里:
indices, docs, store, indexing, search, get, merge,
refresh, flush, warmer, filter_cache, id_cache,
percolate, segments, fielddata, completion
作为对自己的练习，我写了一个小的elasticsearch插件，提供了列出elasticsearch索引的功能，而不需要任何其他信息。你可以在以下网址找到它:

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 + "]");
}
