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
_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:

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
下面是查看db中索引的另一种方法:
curl -sG somehost-dev.example.com:9200/_status --user "credentials:password" | sed 's/,/\n/g' | grep index | grep -v "size_in" | uniq
{ "index":"tmpdb"}
{ "index":"devapp"}
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
}}
您可以查询localhost:9200/_status，这将为您提供关于每个索引和信息的列表。响应看起来像这样:
{
"ok" : true,
"_shards" : { ... },
"indices" : {
"my_index" : { ... },
"another_index" : { ... }
}
}
