ELK 008 learning experiment: the introduction Kibana

A Profile

Kiana is an open source data analysis and visualization platform, it is one of Elastic Stack members, and Elasticsearch designed for collaboration. You can use the data Kiana Elasticsearch index search, view, interact. You can easily make use of charts, tables and maps the data analysis and presentation of a wide range of

Fundamental contents

Kibana core product is equipped with a number of classic features: bar charts, line graphs, pie charts, diagram sun, and so on. Of course, you can also search all your documents.

Two Features

1. Timing Visual Generator

Timing Visual Generator (TSVB) is a timing data visualization tool that uses the full power Elasticsearch polymeric frame may be numerous polymerization and polymerization pipe together so as to display complex data productive manner.

2. geospatial analysis

For many users Elastic Stack's, the "where" is a critical issue. Whether you want to protect your network from attacks or to investigate why the application of site-specific response for a long time, or just make a home network about the car, and search geospatial data plays an important role.

3. Chart

By means of a line graph, area charts and bar graphs , you draw data X / Y axis. FIG hot able to display data in graphical form in FIG hot, the individual values included in the matrix will be represented with a color or color gradient. Pie There is also a variant, i.e. comprising two circular ring chart in FIG annular, segmented pie sheet is no longer, but the annular sheet.

4. Indicators

Visual display a single digit indicators for each polymerization. These indicators show the following: count, average, sum, min / max, standard deviation, percentile, and the like.

Table 5. Data

Data Sheet panels is one of the most common methods of expressing your data. Configure your data table to acquire a specific point in time, or with your real-time data to dynamically synchronize the latest progress.

6. tag cloud

Tag cloud is representative of your text data (usually free text format). Tags are usually single words, the importance of the polymerization index (count, average, sum and the like) is determined, and is emphasized by the font size and color.

7.Vega（定制）

借助 Vega 和 Vega-Lite，无需使用 JavaScript 便能制作出定制可视化。在 Kibana 中创建可视化（无论是单独的，还是地图上的）时，既可以使用来自单一 Elasticsearch 查询的数据，也可以使用来自多个数据源的数据

同时还有非常丰富的插件功能

三安装

3.1 下载包

[root@node1 ~]# cd /usr/local/src/

[root@node1 src]# wget https://artifacts.elastic.co/downloads/kibana/kibana-7.4.2-linux-x86_64.tar.gz

[root@node1 src]# cd /usr/local/kibana

[root@node1 kibana]# useradd kibana

[root@node1 kibana]# chown -R kibana:kibana /usr/local/kibana/

3.2 kibana的配置

[root@node1 kibana]# vi config/kibana.yml

需要配置ElasticSearch的地址，配置文件在/usr/local/kibana/kibana.yml 。在kibana.yml文件需要配置配置的选项如下：

[root@node1 kibana]# grep -Ev "^$|[#;]" config/kibana.yml

server.port: 5601
server.host: "0.0.0.0"
elasticsearch.hosts: ["http://192.168.132.131:9200"]
