elk之elasticsearch 入门

一、概述：

　　1、查看elasticsearch集群的健康状况:

 [root@node115 kibana]# curl -X GET  http://192.168.39.115:9200/_cat/health?v
 epoch      timestamp cluster       status node.total node.data shards pri relo init unassign pending_tasks max_task_wait_time active_shards_percent
  ::  elasticsearch green                                                                          -                100.0%

　　2、查看elasticsearch集群的节点信息：

 [root@node115 kibana]# curl -X GET  http://192.168.39.115:9200/_cat/nodes?v
 ip             heap.percent ram.percent cpu load_1m load_5m load_15m node.role master name
 192.168.39.115                            0.43    0.20     0.22 mdi       *      node-
 192.168.39.175                           0.53    0.42     0.39 mdi       -      node-

　　3、查看index信息：

 [root@node115 kibana]# curl -X GET  http://192.168.39.115:9200/_cat/indices?v
 health status index               uuid                   pri rep docs.count docs.deleted store.size pri.store.size
 green  open   .kibana             e1EFtVxJSeS1jLxeX7kLSg                                 .4kb         .7kb
 green  open   logstash-2017.02. i2rSKoflRtiEZoj9CmgEOA                            .3gb          .1gb
 green  open   logstash-2017.02. zMnftdmDQRShH86XsmwWlw                               .8mb          .4mb
 green  open   filebeat-2017.02. alVH725IQgmwZiYvuW3Dsg                            .8gb          .9gb
 green  open   filebeat-2017.02. E2v3vgcPQz6jrDhxZMprOw                                 4mb            2mb

　　4、创建index

 PUT /customer?pretty    #创建名为customer的index

　　5、查看index的详细信息：

 curl -X GET http://192.168.39.115:9200/logstash-2017.02.15?pretty 

　　6、删除index：

 DELETE /customer?pretty    #删除index （customer）

　　7、查看index上设置信息：

 [root@node115 kibana]# curl -X GET http://192.168.39.115:9200/logstash-2017.02.16/_settings
 {
     "logstash-2017.02.16":{
         "settings":{
             "index":{
                 "refresh_interval":"5s",
                 "number_of_shards":"",
                 "provided_name":"logstash-2017.02.16",
                 "creation_date":"",
                 "number_of_replicas":"",
                 "uuid":"-Bwpq-5TT8mzLMJeU7PQ7A",
                 "version":{
                     "created":""
                 }
             }
         }
     }
 }

　　8、修改index上的配置信息：

二、kafka相关：

　　查看topic

　　　　bin/kafka-topics.sh --list --zookeeper localhost:2181
