Elasticsearch推荐插件篇(head,sense,marvel)

安装head

head插件可以用来快速查看elasticsearch中的数据概况以及非全量的数据，也支持控件化查询和rest请求，但是体验都不是很好。

一般就用它来看各个索引的数据量以及分片的状态。

[root@localnode1 bin]# ./plugin install mobz/elasticsearch-head

安装sense

sense插件可以方便的执行rest请求，但是中文输入的体验不是很好。

安装sense只需要在Kibana端安装插件即可，插件会自动安装到kibana的应用菜单中。

[hdfs@localnode1 bin]$ kibana plugin -install elastic/sense
-bash: kibana: command not found
[hdfs@localnode1 bin]$ ./kibana plugin -install elastic/sense
Please specify either --install, --remove, or --list.
[hdfs@localnode1 bin]$ ./kibana plugin --install elastic/sense

安装完成后，可以通过导航面板进入，也可以直接访问http://localhost:5601/app/sense

安装marvel

marvel工具可以帮助使用者监控elasticsearch的运行状态，不过这个插件需要license。安装完license后可以安装marvel的agent，agent会收集elasticsearch的运行状态。

然后在Kibana段安装marvel插件，这个插件与sense类似，都集成在kibana的导航列表面。
