我正在尝试从我的prometheus堆栈发送自定义警报。
我使用prometheus-community helm chart安装了prometheus。我还安装了一个mailhog来捕获alertmanager发送的邮件。
首先，我创建了alertmanagerconfig:
kind: AlertmanagerConfig
metadata:
name: mailhog
namespace: prometheus
spec:
receivers:
- name: mailhog
emailConfigs:
- to: "test@fake.com"
from: "cluster@fake.com"
smarthost: "mailhog.mailhog.svc.cluster.local:1025"
requireTLS: false
route:
groupBy:
- severity
groupInterval: 30s
groupWait: 30s
receiver: mailhog
repeatInterval: 1m
这是工作或多或少，因为我收到一些警报配置默认当我安装普罗米修斯图表。
然而，当我想创建自己的自定义警报时，它似乎被bug:
apiVersion: monitoring.coreos.com/v1
kind: PrometheusRule
metadata:
name: prom-rule-test
namespace: prometheus
labels:
release: prometheus
spec:
groups:
- name: ruleTest
rules:
- alert: test
expr: vector(1)
labels:
severity: warning
我可以在prometheus web UI中看到规则，并且可以在" fire "中看到警告。状态。但是，我的邮箱里没有收到任何东西。
我不明白为什么。你知道吗?

@Abdullah Barrak谢谢你的回答。这已经完成了，我添加了标签release: prometheus
确保为Prometheus拾取PrometheusRule添加所需的标签，以及ruleSelector::链接。
