Gatling FrontLine是Gatling的管理界面，其中包括用于集成和自动化的高级指标和高级功能。

## 使用 ##

首先，到[官网][Link 1]下载最新版的gatling：

https://repo1.maven.org/maven2/io/gatling/highcharts/gatling-charts-highcharts-bundle/2.3.1/gatling-charts-highcharts-bundle-2.3.1-bundle.zip

然后解压缩到本地路径:

unzip gatling-charts-highcharts-bundle-2.3.1.zip
    
    mv gatling-charts-highcharts-bundle-2.3.1 gatling

然后看一下打压脚本:

import io.gatling.core.Predef._ 
    import io.gatling.http.Predef._
    import scala.concurrent.duration._
    
    class HelloSimulation extends Simulation {
    
      val httpConf = http 
        .baseURL("http://192.168.99.100:30888") 
    
      val scn = scenario("HelloSimulation").during(30) {
        exec(http("hello_1")
        .get("/lmsia-abc/api/"))
      }
    
      setUp(
        scn.inject(atOnceUsers(2000))
      ).protocols(httpConf)
    }

如上，Gating的打压脚本稍微复杂一些:

*  服务根地址192.168.99.100:30888
 *  访问的get请求"/lmsia-abc/api/"
 *  并发2000个用户

执行一下打压：

gatling.sh -sf . -s HelloSimulation

结果中可以直接看到各项统计结果：
