ElasticSearch的状态查看
1.1 基本状态查看
集群状态
get _cluster/health
get _cluster/state
get _cluster/settings
get _cluster/pending_tasks
注:
get _cluster/health查看分片状态
get _cluster/state查看nodes,metadata, indices信息
节点状态
get _cat/nodes?v
#查看ip|heap.percent|ram.percent |load_1m|load_5m|load_15m |node.role |master |name
get _nodes
get _nodes/stats
#这两条命令相同
#主要角色
"roles": [
"master",
"data",
"ingest"
],
get _nodes/hot_threads
get _nodes/node-1/hot_threads

官网原话： 1、Allocate an unassigned shard to a node. Accepts the index and shardfor index name and shard number, and node to allocate the shard to. It alsoaccepts allow_primary flag to explicitly specify that it is allowed toexplicitly allocate a primary shard (might result in data loss).
2、Warning：Theallow_primary parameter will force a new empty primary shard to beallocatedwithout any data. If a node which has a copy of the original shard(including data) rejoins the cluster later on, that data will be deleted: theold shard copy will be replaced by the new live shard copy.
