Install Chronograf
前言
InfluxDB 是一款高性能的时序数据库，见长于标量的时序存储
类似于 Elasticsearch 的 ELK 技术栈，InfluxDB 也有一套 TICK 技术栈
其中 Chronograf 是展示数据的前端 UI 组件
Chronograf is the user interface component of InfluxData’s TICK Stack. It makes the monitoring and alerting for your infrastructure easy to setup and maintain. It is simple to use and includes templates and libraries to allow you to rapidly build dashboards with real-time visualizations of your data
这里分享一下 Chronograf 的安装方法
Tip: 当前的版本为 chronograf-1.4.1.2

[root@much ~]#依赖
在 TICK 技术栈中，Chronograf 的正常工作依赖 InfluxDB
Telegraf 是建议安装的，但并非必要，因为它可以为系统不断提供新数据
Kapacitor 是可选安装的，数据处理与报警处理等高级功能才需要依赖它

[root@much telegraf]#进行访问
Username 和 Password 可以为空
chronograf
查看 hostlist
chronograf
进入可以查看主机的负载信息(由telegraf在默认配置下收集的标量信息)
chronograf
也可以交互式探索数据
chronograf
非常直观易用，上面是查询语句，中间是标量信息，下面是图形
总结
chronograf 作为 influxdb 的前端数据展示组件，与 influxdb 的对接非常简单(默认不作配置都是直接连接的本地 influxdb)
界面简洁美观，和 grafana 风格比较像
