ElasticSearch之cat allocation API

查看各节点上各个shard的硬件使用情况，命令样例如下：

curl -X GET "https://localhost:9200/_cat/allocation?v=true&pretty" --cacert $ES_HOME/config/certs/http_ca.crt -u "elastic:ohCxPH=QBE+s5=*lo7F9"

执行结果如下：

shards disk.indices disk.used disk.avail disk.total disk.percent host      ip        node1       12.6kb    57.1gb     34.5gb     91.6gb           62 127.0.0.1 127.0.0.1 jackie-ubuntu

查看帮助，命令如下：

curl -X GET "https://localhost:9200/_cat/allocation?v=true&help=true&pretty" --cacert $ES_HOME/config/certs/http_ca.crt -u "elastic:ohCxPH=QBE+s5=*lo7F9"

执行结果输出如下：

shards       | s               | number of shards on node
disk.indices | di,diskIndices  | disk used by ES indices
disk.used    | du,diskUsed     | disk used (total, not just ES)
disk.avail   | da,diskAvail    | disk available
disk.total   | dt,diskTotal    | total capacity of all volumes
disk.percent | dp,diskPercent  | percent disk used
host         | h               | host of node
ip           |                 | ip of node
node         | n               | name of node
node.role    | r,role,nodeRole | node roles
