      <description>做告警最常见的状态不是没告警，而是有两套甚至三套并行运行的告警系统，渠道交叉、规则重叠、silence 写得到处都是。本文给出从混乱状态收敛成统一治理的完整路径，包含可直接 1:1 复制部署的全量 yaml、脚本与配置。</description>

      <guid>https://socake.github.io/posts/prometheus-error-budget-alerting/</guid>
      <description>错误率告警有一个致命问题：它不告诉你问题有多紧急。1% 的错误率，持续 2 小时和持续 10 分钟，对 SLO 的威胁完全不同。燃烧率告警从 Error Budget 消耗速度出发，让每一次告警都携带&amp;quot;紧急程度&amp;quot;信息。</description>
