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.

/
