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..
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
}}
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
