Hi. I am using Blackbox Exporter v 0.18.0 for generating Host Down Alerts.
Below is the configured rule.
- alert: HostDown
expr: probe_success{job=~"Ping-All-Servers"} == 0
for: 1m
labels:
severity: "CRITICAL"
annotations:
summary: "Server is Down - *{{ $labels.instance }}*"
identifier: "*Cluster:* `{{ $labels.cluster }}`, *node:* `{{
$labels.node }}` "
Now, when I am checking my Prometheus' alert page
http://x.x.x.x:9090/alerts, I see 7-8 HostDown in PENDING state everytime,
and when at the same time I check my Blackbox Exporter's debug log, I don't
see any Probe Failed for my ICMP module for those instances.
I am missing something here?
Thanks in advance!
