我使用_stats/indexes端点来获得一个json blob数据，然后用jq进行过滤。

curl 'localhost:9200/_stats/indexes' | jq '.indices | keys | .[]'

"admin"
"blazeds"
"cgi-bin"
"contacts_v1"
"flex2gateway"
"formmail"
"formmail.pl"
"gw"
...

如果你不想要引号，给jq添加一个-r标志。

是的，端点是索引，数据键是索引，所以他们也无法做出决定:)

我需要它来清理内部安全扫描(nessus)创建的这些垃圾索引。

PS:如果您打算从命令行与ES交互，我强烈建议您熟悉jq。

我还推荐使用/_cat/ indexes，它提供了一个人类可读的索引列表。

要获得集群中所有索引的简明列表，请调用

curl http://localhost:9200/_aliases

这将为您提供索引及其别名的列表。

如果你想要漂亮的打印，添加pretty=true:

curl http://localhost:9200/_aliases?pretty=true

如果你的索引是old_deuteronomy和mungojerrie，结果会是这样的:

{
  "old_deuteronomy" : {
    "aliases" : { }
  },
  "mungojerrie" : {
    "aliases" : {
      "rumpleteazer" : { },
      "that_horrible_cat" : { }
    }
  }
}

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 + "]");
}

我用它来得到所有的指标:

$ curl --silent 'http://127.0.0.1:9200/_cat/indices' | cut -d\  -f3

有了这个列表，你就可以……

例子

$ curl -s 'http://localhost:9200/_cat/indices' | head -5
green open qa-abcdefq_1458925279526           1 6       0     0   1008b    144b
green open qa-test_learnq_1460483735129    1 6       0     0   1008b    144b
green open qa-testimportd_1458925361399       1 6       0     0   1008b    144b
green open qa-test123p_reports                1 6 3868280 25605   5.9gb 870.5mb
green open qa-dan050216p_1462220967543        1 6       0     0   1008b    144b

要获得上面的第三列(索引的名称):

$ curl -s 'http://localhost:9200/_cat/indices' | head -5 | cut -d\  -f3
qa-abcdefq_1458925279526
qa-test_learnq_1460483735129
qa-testimportd_1458925361399
qa-test123p_reports
qa-dan050216p_1462220967543

注意:你也可以使用awk '{print $3}'来代替cut -d\ -f3。

列标题

还可以使用?v作为查询的后缀，以添加列标头。这样做会打破缺口……方法，所以我建议使用awk..此时的选择。

$ curl -s 'http://localhost:9200/_cat/indices?v' | head -5
health status index                              pri rep docs.count docs.deleted store.size pri.store.size
green  open   qa-abcdefq_1458925279526             1   6          0            0      1008b           144b
green  open   qa-test_learnq_1460483735129      1   6          0            0      1008b           144b
green  open   qa-testimportd_1458925361399         1   6          0            0      1008b           144b
green  open   qa-test123p_reports                  1   6    3868280        25605      5.9gb        870.5mb

curl -XGET 'http://localhost:9200/_cluster/health?水平=指数'

这将输出如下所示
