问题描述
我正在使用Prometheus运算符0.3.4和警报管理器0.20，但它不起作用，即我看到警报被触发(在Alert选项卡上的Prometheus UI上)，但是我没有收到电子邮件的任何警报.通过查看日志，我看到以下内容，您知道吗?请以粗体显示警告，也许是原因，但不确定如何解决...
Im using prometheus operator 0.3.4 and alert manager 0.20 and it doesnt work, i.e. I see that the alert is fired (on prometheus UI on the alerts tab) but I didnt get any alert to the email. by looking at the logs I see the following , any idea ? please see the warn in bold maybe this is the reason but not sure how to fix it...

错误表明它在解析中失败，名为alertmanager-monitoring-prometheus-oper-alertmanager-0的容器名称已启动并正在运行，但是它尝试解决:查找alertmanager-monitoring-prometheus-oper-alertmanager-0.alertmanager-operated.monitoring.svc不确定原因...
The error says it failed in the resolve , the pod name called alertmanager-monitoring-prometheus-oper-alertmanager-0 which is up and running however it try to resolve : lookup alertmanager-monitoring-prometheus-oper-alertmanager-0.alertmanager-operated.monitoring.svc not sure why...
这是kubectl get svc -n mon

推荐答案
正确的调试步骤可帮助解决以下情况:
Proper debug steps to help with these kind of scenarios:
- 启用Alertmanager调试日志:添加参数--log.level = debug
- 验证Alertmanager集群是否正确形成(检查/status端点并验证所有对等节点都已列出)
- 验证Prometheus是否正在向所有Alertmanager对等方发送警报(检查/status端点并验证是否列出了所有Alertmanager对等方)
- 端到端测试:生成测试警报，应在Prometheus UI中看到警报，然后在Alertmanager UI中看到警报，最后应该看到警报通知.
