启用prometheus插件

首先在Konga控制台启用prometheus插件，如下图所示，直接在全局范围启用该插件，关于prometheus插件更多配置详见官方文档。
konga->PLUGINS->Add Global Plugins ->Analytics & Monitoring->prometheus
启动好之后在服务器上测试

http://localhost:8001/metrics

如果见到类似以下数据说明启动成功

# HELP kong_bandwidth Total bandwidth in bytes consumed per service/route in Kong
# TYPE kong_bandwidth counter
kong_bandwidth{service="baidu",route="baidu",type="egress"} 92622
kong_bandwidth{service="baidu",route="baidu",type="ingress"} 9677
kong_bandwidth{service="google",route="google",type="egress"} 3565288
kong_bandwidth{service="google",route="google",type="ingress"} 1449
kong_bandwidth{service="alibaba",route="alibaba",type="egress"} 1983
kong_bandwidth{service="alibaba",route="alibaba",type="ingress"} 51364

安装prometheus

在服务器使用docker命令安装

首先配置prometheus.yml文件，配置信息如下

文档地址：/home/prometheus/prometheus.yml:

global:
  scrape_interval: 15s
  evaluation_interval: 60s
  scrape_timeout: 10s

scrape_configs:
  - job_name: prometheus
    scrape_interval: 15s
    scrape_timeout: 10s
    metrics_path: /metrics
    scheme: http
    static_configs:
      - targets: ['IP:8001']
        labels:
          instance: kong

上面的IP要使用实际kong的IP，且不能使用localhost代替

启动prometheus

docker run -p 9090:9090 --name prometheus   -v /home/prometheus/prometheus.yml:/etc/prometheus/prometheus.yml     -d prom/prometheus

检查prometheus是否安装成功

http://IP:9090/graph

在搜索框内输入kong_bandwidth，看是否能查询出数据，能查询说明安装成功
