一、查看当前es上的所有索引
curl -XGET "http://127.0.0.1:9200/_cat/indices" # 查看索引缩略信息
curl -XGET "http://127.0.0.1:9200/_cat/indices?v" # 查看索引详细信息
二、查看elasticsearch集群状态
curl -sXGET "http://127.0.0.1:9200/_cluster/health?pretty"
{ "cluster_name" : "elasticone", "status" : "yellow", "timed_out" : false, "number_of_nodes" : 1, "number_of_data_nodes" : 1, "active_primary_shards" : 541, "active_shards" : 541, "relocating_shards" : 0, "initializing_shards" : 0, "unassigned_shards" : 541, "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" : 50.0 }
三、查看集群节点信息
curl -XGET "http://127.0.0.1:9200/_cat/nodes?v"
四、查看节点进程信息
curl -XGET "http://127.0.0.1:9200/_nodes/process?pretty"
五、查看索引统计信息
curl -XGET "http://127.0.0.1:9200/_stats?pretty"
六、查看指定索引统计信息
curl -XGET "http://127.0.0.1:9200/索引名/_stats?pretty"
curl -XGET "http://127.0.0.1:9200/logstash-2018.10.21/_stats?pretty"
七、查看热点线程
curl -XGET "http://127.0.0.1:9200/_nodes/hot_threads?pretty"
八、查看指定索引信息
curl -XGET "http://127.0.0.1:9200/索引名/_mapping?pretty"
curl -XGET "http://127.0.0.1:9200/logstash-2018.10.21/_mapping?pretty"
九、查看所有节点jvm信息
curl -XGET "http://127.0.0.1:9200/_nodes/stats/jvm?pretty"
十、查看指定节点jvm信息
curl -XGET "http://127.0.0.1:9200/_nodes/节点名/stats/jvm?pretty"
curl -XGET "http://127.0.0.1:9200/_nodes/searchnode-01/stats/jvm?pretty"
十一、删除全部索引
curl -XDELETE "http://127.0.0.1:9200/*?pretty"
十二、删除指定索引
curl -XDELETE "http://127.0.0.1:9200/索引名?pretty"
curl -XDELETE "http://127.0.0.1:9200/logstash-2018.10.19?pretty"
curl -XDELETE "http://127.0.0.1:9200/logstash-2018.10.19?pretty" { "acknowledged" : true }
# 删除历史索引思路
# step1 取出要删除的索引名
curl -sXGET "http://127.0.0.1:9200/_cat/indices"|awk '{print $3}'|grep 2018.10 # 2018.10月的所有索引
# step2 使用for循环调用接口删除之
for i in `curl -sXGET "http://127.0.0.1:9200/_cat/indices"|awk '{print $3}'|grep 2018.10`;do curl -XDELETE "http://127.0.0.1:9200/$i?pretty";done
十三、查看线程池配置
curl -XGET "http://127.0.0.1:9200/_nodes/thread_pool/"
