使用prometheus-alertmanager通过Grafana UI发送警报电子邮件

Question

I am trying to test sending email alerts through the grafana UI using the prometheus-alertmanager notification channel. I have added the stmp details in the config file of the alertmanager. When I try to test it says that the email has been sent but nothing really happens. When I add the same email configuration to the grafana.ini file and add the email notification channel in the UI, I am able to send the test notification. I am using the following helm chart to install it - > https://github.com/helm/charts/tree/master/stable/prometheus-operator Here is the alertmanager config file.

  config:
    global:
      resolve_timeout: 5m
      smtp_smarthost: 'email-smtp.us-east-1.amazonaws.com:587'
      smtp_from: 'redacted'
      smtp_auth_username: 'redacted'
      smtp_auth_password: 'redacted'

route:
  group_by: ['job']
  group_wait: 30s
  group_interval: 5m
  repeat_interval: 12h
  receiver: 'null'
  routes:
  - match:
      alertname: DeadMansSwitch
    receiver: 'null'
receivers:
- name: 'null'

This is the grafana log.

What am I doing wrong here ?

Answer 1

The log output from Prometheus AlertManager is missing. If the alert manager config is full, then you miss 2 more lines after

• name: 'null'

email_configs:
  - to: 'myemail@test.com'
