2.配置prometheus对alertmanager的链接

编辑prometheus.yaml文件，新增

alerting:
      alertmanagers:
      - static_configs:
        - targets:
          - alertmanager:9093

3.配置预警rules

编辑prometheus.yaml文件，新增以下代码

rule_files:
    - "/data/istio/prometheus-rules/*.rules.yml"

挂载规则文件：

根据文件生成configMap:

kubectl create configmap prometheus-rules --from-file=prometheus-rules -o yaml --namespace=istio-system

注意：rules文件夹名称为prometheus-rules,rules文件为yml格式，如：

test.rules.yml

groups:

- name: my-group-name

  interval: 30s   # defaults to global interval

  rules:

  - record: instance:errors:rate5m

    expr: rate(errors_total[5m])

  - record: instance:requests:rate5m

    expr: rate(requests_total[5m])

  - alert: HighErrors

    # Expressions remain PromQL as before and can be spread over

    # multiple lines via YAML’s multi-line strings.

    expr: |

      sum without(instance) (instance:errors:rate5m)

      /

      sum without(instance) (instance:requests:rate5m)

    for: 5m

    labels:

      severity: critical

    annotations:

      description: "stuff's happening with {{ $labels.service }}"
