45.esrally性能分析结果图形化展示

0、前提

安装elasticsearch的最新版本，目前是2.3.4版本。 
elsticsearch新增扮演的角色是：rally分析结果会存储到elasticsearch。

1、运行esrally 高级配置模式

高级配置模式和普通模式的区别：普通模式只需要配置jdk的环境变量路径。 
而高级模式，需要配置：当前本机已安装elasticsearch的监听端口以及ES配置的主机名称。

高级配置模式详情：

[elasticsearch@laoyang root]$ esrally configure --advanced-config

  ____ ____
  / __ \____ _/ / /_ __
  / /_/ / __ `/ / / / / /
 / _, _/ /_/ / / / /_/ /
/_/ |_|\__,_/_/_/\__, /
  /____/

Running advanced configuration. You can get additional help at:

  https://esrally.readthedocs.io/en/latest/configuration.html

WARNING: Will overwrite existing config file at [/home/elasticsearch/.rally/rally.ini]

[✓] Configuration successfully written to [/home/elasticsearch/.rally/rally.ini]. Happy benchmarking!

To benchmark the currently checked out version of Elasticsearch with the default benchmark run:

  esrally

3、在head插件前端和kibana前端看输出结果。

head插件会显示：新增的索引：rally-2016. 
 
 
 
kibana配置参考： 
https://elasticsearch-benchmark-analytics.elastic.co/app/kibana#/visualize/edit/Index-disk-usage （官网esrally性能测试） 
下图信息，如果每天运行一次性能测试，就能够跑出性能曲线。（横轴：日期，纵轴：性能指标）
