CCE Prometheus监控指标数据统一remotewrite到华为云AOM2.0服务，可以在AOM2.0服务中展示Prometheus采集的指标数据，并根据业务实际诉求，实现基于指标的的告警通知。

CCE监控插件对接AOM:

AOM查看nginx-ingress

三 nginx-ingress关键指标

确保Prometheus已成功抓取nginx-ingress指标

• nginx-ingress配置热加载失败次数
  count(nginx_ingress_controller_config_last_reload_successful{} == 0)

• nginx-ingress每个nginx-ingress-controller实例的连接数
  sum(nginx_ingress_controller_nginx_process_connections) by (controller_namespace,controller_pod)

• nginx-ingress每个nginx-ingress-controller实例中process数
  nginx_ingress_controller_nginx_process_num_procs

• nginx-ingress每个nginx-ingress-controller实例的每秒请求数
  sum(irate(nginx_ingress_controller_requests{}[1m])) by (controller_namespace,controller_pod)

• nginx-ingress请求时延
  histogram_quantile(0.90, sum(rate(nginx_ingress_controller_request_duration_seconds_bucket{status="200"}[1m])) by (le, ingress, host, path)) * 1000

  histogram_quantile(0.95, sum(rate(nginx_ingress_controller_request_duration_seconds_bucket{status="200"}[1m])) by (le, ingress, host, path)) * 1000

  histogram_quantile(0.99, sum(rate(nginx_ingress_controller_request_duration_seconds_bucket{status="200"}[1m])) by (le, ingress, host, path)) * 1000

• 请求失败率
  sum(rate(nginx_ingress_controller_requests{status=~"[4-5].*"}[5m])) / sum(rate(nginx_ingress_controller_requests{}[5m])) * 100

四 如何根据nginx-ingress指标进行告警
