监控运行状态

curl -X GET "localhost:9200/_cluster/health"

输出:

{"cluster_name":"elasticsearch","status":"green","timed_out":false,"number_of_nodes":1,"number_of_data_nodes":1,"active_primary_shards":0,"active_shards":0,"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":100.0}

格式化后输出

添加pretty参数

curl -X GET "localhost:9200/_cluster/health?pretty=true"

输出:

{
  "cluster_name" : "elasticsearch",
  "status" : "green",
  "timed_out" : false,
  "number_of_nodes" : 1,
  "number_of_data_nodes" : 1,
  "active_primary_shards" : 0,
  "active_shards" : 0,
  "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" : 100.0
}

status字段

当前集群(单机es只有green,curl不通则表明服务已宕机)在总体上是否工作正常。它的三种颜色含义如下:

  • green:所有的主分片和副本分片都正常运行。
  • yellow:所有的主分片都正常运行,但不是所有的副本分片都正常运行。
  • red:有主分片没能正常运行。
