将[http-simulator](../http-simulator)导入Eclipse IDE 9 | * Review代码理解模拟器原理 10 | * 以Spring Boot方式运行模拟器 11 | * 通过`http://localhost:8080/prometheus`查看metrics 12 | * 通过Postman启用随机Spike模式 13 | 14 | ``` 15 | curl -X POST http://SERVICE_URL:8080/spike/random 16 | ``` 17 | 18 | #### 2. 安装运行Promethus 19 | 20 | 下载[Prometheus 2.4.3 for Windows](https://github.com/prometheus/prometheus/releases/download/v2.4.3/prometheus-2.4.3.windows-amd64.tar.gz)，并解压到本地目录。 21 | 22 | 调整全配置项 23 | ```yml 24 | 25 | # my global config 26 | global: 27 |
