apisix 开启 prometheus

安装完了 apisix 后，想对流量做一个监控，发现 apisix 已经有了该项功能，于是记录一下。

本次环境为k8s，采用的是helm 安装的 apisix + apisix-ingress-controller.

开启 prometheus

默认情况下，apisix是已经开启了prometheus。如下：

plugin_attr:
  prometheus:
    enable_export_server: false

这种方式是通过apisix-admin来暴露metrics的。但是访问的话还是需要通过public-api插件去访问。

添加ingress

下面是我的ingress 配置。记得将namespace配置成和apisix-ingress一致。

apiVersion: apisix.apache.org/v2
kind: ApisixRoute
metadata:
  name: prometheus-route
  namespace: ingress-apisix
spec:
  http:
  - name: prometheus-metrics
    match:
      hosts:
      - apisix-prometheus.cootekos.com
      paths:
      - /apisix/prometheus/metrics*
    backends:
    - serviceName: apisix-admin
      servicePort: 9180
    plugins:
    - name: public-api
      enable: true

访问

访问https://your-domain/apisix/prometheus/metrics 就可以看到指标了。但是缺少了很多关键性的指标。还需要在apisix-dashboard中开启prometheus插件。

prometheus插件

然后访问连接可以拿到指标：

prefer_name 配置

根据文档中的说明: prefer_name配置开启，将会打印route/service的名字，而不是ID。我这边需要知道对应的service名字，所以开启了。

配置grafana

直接下载 grafana 面板的json文件。然后导入进去就行。

效果图如下：

grafana-apisix
