我正在使用 Prometheus Blackbox-exporter ICMP 设置监控 N 个系统的 UP/Down 状态。
黑盒导出器配置：
modules:
icmp:
prober: icmp
timeout: 5s
icmp:
preferred_ip_protocol: "ip4"
普罗米修斯配置：
global:
scrape_interval: 15s
external_labels:
monitor: 'codelab-monitor'
scrape_configs:
- job_name: 'prometheus'
scrape_interval: 5s
static_configs:
- targets: ['prometheus:9090']
- job_name: 'blackbox'
metrics_path: /probe
params:
module: [icmp]
static_configs:
- targets: ['192.168.1.29', '987.234.121.1']
labels:
group: 'Build'
- targets: ['161.92.248.21', '161.92.3.185', '10.10.4.18']
labels:
group: 'RND'
relabel_configs:
- source_labels: [__address__]
target_label: __param_target
- source_labels: [__param_target]
target_label: instance
- target_label: __address__
replacement: blackboxexporter:9115
blackbox-exporter 探测结果准确且看起来不错注意：结果显示无法访问的目标失败，这看起来不错

Prometheus 结果不准确。这显示所有目标都是 UP 注意：预期结果是失败目标应该显示为 0/1
blackbox (5/5 up)
