linux - “在这种情况下不允许映射值”Alertmanager.yml

问题描述

我将 Alertmanager 0.20 与 Prometheus 一起使用。alertmanager.yml 的配置没问题，但是如果我尝试在代理后面添加 proxy_url，并且根据文档配置，我们需要在 http_config 下设置 proxy_url。

使用这两个，Alertmanager 开始失败并出现以下错误：

systemd[1]: Started Alert Manager.

我的警报管理器版本：

alertmanager, version 0.21.0 (branch: HEAD, revision:
4c6c03ebfe21009c546e4d1e9b92c371d67c021d)   build user:      
root@dee35927357f   build date:       20200617-08:54:02   go version: 
go1.14.4

我的 alertmanager.yml

global:
http_config:
proxy_url: http://ip:port
 smtp_smarthost: smtp_server_name:port
 smtp_from: from@email.com
 smtp_auth_username: auth@email.com
route:
  group_by: [alertname]
  repeat_interval: 1m
  receiver: live-monitoring

receivers:
- name: live-monitoring
  email_configs:
  - to: to@email.com

知道如何使 alertmanager 工作并使用代理配置发送电子邮件吗？而且我不能在 route: 或接收者之前设置 http_config 和 proxy_url，否则

field http_config not found in type config.plain

解决方案

缩进在 YAML 中很重要。您似乎在配置中的多个位置损坏了它。正确结构的快速示例：

global:
  http_config:
    proxy_url: ....
  smtp_smarthost:
  ...
route:
  ...
receivers:
  ...

请注意开头的空格以及它们如何表示配置选项的嵌套。
