1. 查看ES集群健康状态
curl -XGET 'http://localhost:8200/_cluster/health?pretty'结果:
{ "cluster_name" : "if2c", "status" : "yellow", //集群的状态红绿灯,绿:健康,黄:亚健康,红:病态 "timed_out" : false, "number_of_nodes" : 1, //节点数 "number_of_data_nodes" : 1, //数据节点数 "active_primary_shards" : 3, //分片数,3个Index库 "active_shards" : 3, "relocating_shards" : 0, "initializing_shards" : 0, "unassigned_shards" : 3 //未指定节点,配置了复本,仅使用一台机器部署会出现这种情况 }
curl -XGET 'http://localhost:8200/_cluster/health/zh?pretty' 一个index库
curl -XGET 'http://localhost:8200/_cluster/health/zh,west?pretty' 多个index库
level=indices, shards, cluster
curl -XGET 'http://localhost:8200/_cluster/health?level=indices&pretty'
curl -XGET 'http://localhost:8200/_cluster/health?level=shards&pretty'
