查看样例数据

登录 Kibana

浏览器输入:http://localhost:5601

地址格式为:http://kibana地址:kibana所使用的端口,均为在 kibana.yml 配置文件中定义的。

在左上方选择样例数据的索引,右上方选择需要查询的时间范围,即可看到我们需要的数据,如下:

默认会展示所有字段,当然,也可以在左侧栏选择需要展示的字段,如下:

这些数据也可以以表或者以JSON形式展示,如下:

将鼠标移动到某个字段上,会出现上下的箭头,此时便可以根据箭头进行排序,如下:

开发工具 Dev Tools

Dev Tools 是 Kibana 中最常用的功能,点击导航栏 -> Management -> 开发工具即可使用。

点击控制台 -> 设置,可以看到一些字体、换行等设置。

点击 Grok Debugger 可以进行一些正则调试,与 Logstash 结合解析日志。

删除索引 test

  • 根据索引名称删除
DELETE test?pretty
  • 可以一次删除多个索引(以逗号间隔)删除所有索引 _all 或通配符 *

查看索引模板

GET _template                          #查看所有索引摸板
GET _template/temp*                    #查看以temp开头的索引模板
GET _template/template_1,template_2    #查看template_1和template_2索引摸板
GET _template/template_name            #查看名称为template_name的索引摸板
