Prometheus blackbox-exporter ICMP ping监视配置，所有目标都显示出来

Question

我正在使用Prometheus Blackbox-exporter ICMP设置监视N个系统的UP / DOWN状态。

blackbox-exporter配置：

modules:
  icmp:

blackbox-exporter探测结果准确且看起来不错注意：结果显示无法到达的目标失败，这看起来不错

icmp    192.168.3.185   Failure Logs
icmp    161.92.248.21   Success Logs

Prometheus结果不准确。这表明所有目标都在注意：预期结果是失败目标，应该显示为0/1

我相信在Prometheus中查询probe_success指标将为您提供预期的结果。

[通常在使用blackbox-exporter时，我们会根据此指标创建基本的“向上/向下”警报。
