Kibana是ELK中K的全称,那它是用来干什么的呢?Kibana有非常丰富的可视化分析组件,比如基本图表、VEGA图表、Canvas图表、表格、时序数据图,还有仪表板让你把各种图表汇聚到一起做可视化分析,下面作者就和大家一起走进Kibana。
在Kibana的官网最长看到的一句话就是一图胜过千万行日志那kibana到底有哪些功能?官方的准确解释如下:
Kibana Lens
时序可视化生成器
地理空间分析
图表
指标
数据表
标签云图
Vega(定制)
Machine Learning
Kibana Lens
Kibana Lens 是一个直观易用的 UI,能够通过拖放体验简化数据可视化过程。无论想探索数十亿条日志,还是希望从网站流量中找出趋势,通过 Lens,您只需轻点几下鼠标便可从数据中收获洞见,之前无需拥有任何 Kibana 经验!时序可视化生成器
时序可视化生成器 (TSVB) 是一个时序数据可视化工具,利用了 Elasticsearch 聚合框架的全部威力,可将无数的聚合和管道聚合整合在一起,从而以富有成效的方式展示复杂数据地理空间分析
对 Elastic Stack 的很多用户而言,“哪里”是一个至关重要的问题。无论您希望保护自己的网络免受攻击,还是调查为何特定地点的应用程序响应时间长,或者只是打个网约车回家,地理空间数据和搜索都发挥着重要的作用图表
借助线状图、面积图和柱形图,您能够在 X/Y 轴上绘制数据。热点图能够以图形方式展示数据,在热点图中,矩阵中所包含的单独值会以颜色或渐变色表示。饼图还有一种变体,即包含两个圆的环形图,在环形图上,被分割的不再是饼片,而是环形片。Machine Learning
讲了那么多Kibana的功能后,如何安装Kibana应该才是很多朋友关心的。不用着急,打开kibana的官方文档,找到对应的下载页面

其他安装方式
https://www.elastic.co/guide/en/kibana/6.8/install.html
Kibana是安装完毕了,那我们要怎么使用它呢?下面就对Kibana常用模块进行讲解
如下图,进入Kibana首先需要的是把测试数据导入ES中进行模拟测试数据主要类型
电商数据
航班数据
简单的web日志
3.2 Dev Tools简介
DevTools 作为Kibana的一个功能模块,主要有三种Console,Search Profiler,Grok Debugger.我们主要讲一下最长见的Console.各类查询快捷键
Console提供了一些快捷键,来提高使用效率。
快捷键 | 说明 |
---|---|
ctrl/cmd + enter | 提交请求 |
ctrl/cmd + alt/option + L | 叠起/打开当前代码 |
ctrl/cmd + / | 打开api对应官当 |
ctrl/cmd + up/down | 跳到上一个或下一个执行块 |
ctrl/cmd + I | 缩进格式 |
esc | 关闭当前提示框 |
用户角色权限管控
除了以上模块,Kibana的Management模块也是很有用的,这个模块可以让你更好地管理用户和角色,为你打造最小化的用户和权限,具体使用,本文就不详细讲解
Kibana和Elasticsearch一样也是有一些开源插件的,具体如下图:
https://www.elastic.co/guide/en/kibana/current/known-plugins.html
# 安装 kibana 插件bin/kibana-plugin install plugin_location# 查看已安装的 kibana 插件bin/kibana-plugin list# 异常已经安装的 kibana 插件bin/kibana remove plugin_name
