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。

导入样例数据

查看样例数据

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：

查看样例数据图表

这是系统内置的一些数据图表方便我们快速了解 Kibana。

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。

基础查询

更加详细的查询语法参考：https://www.elastic.co/guide/en/elasticsearch/reference/current/query-dsl.html

拖动字段http_code到中间

会自动根据此字段生成图表

可以选择下方不同的图表进行展示

也可以在下拉菜单中选择不同的图像

图表也会根据查询动态变化，比如要查询 http_code 的值为 200，图标就会变化为下图这样

还可以选择图例展示的位置

保存

KQL 查询

一般查询

查询 http_code 的值为 302 的数据

http_code : 302

条件运算符查询

查询 http_code 的值是大于等于 400 的数据

http_code > = 400（代码格式会乱,正确的是> =中间没有空格）

逻辑运算符查询

查询 http_code 的值为大于 200 并且 method 的值是 POST 的数据

http_code > 200 and method : POST

查询 http_code 的值为大于 200 或者 method 的值是 GET 的数据

http_code > 200 or method : GET

通配符

查询某个字段的值存在的数据，存在则返回数据，不存在则返回为空
