Why am I seeing the VM availability metric reflect VM downtime when I observe no impact?
为什么看到 VM 可用性指标反映了 VM 停机时间但却没有观察到任何影响？
The VM availability metric is calculated as an aggregation of the health checks stated here. When the guest agent is incorrectly installed or missing altogether, we interpret the guest heartbeat signal as unhealthy, and therefore emit a metric value of 0, which may be inaccurate. We have plans to move away from the aggregation model and rely only on one, unified high confidence signal from the host server. This work is already underway and will ensure our monitoring offerings give consistent values. We anticipate this work to be completed through the course of 2023.
虚拟机可用性指标的计算结果是运行状况检查的聚合，如此处所述。 当来宾代理安装不正确或完全缺失时，我们将来宾检测信号解释为“运行不正常”，因此发出的度量值为 0，这可能不准确。 我们计划弃用聚合模型，而只依赖于来自主机服务器的一个统一的高置信度信号。 这项工作已在进行中，将确保我们的监视产品/服务提供一致的值。 我们预计这项工作将在 2023 年完成。
