Hi. I have configured an alert to get notified whenever any of my Network
Interfaces goes down. Now, on some servers some interfaces we have made
down intentionally and I want to exclude those interfaces for those
particular servers from the alert.
What is the best possible way to do this? I know I can silence the alert,
but that wouldn't be a good solution as the interface would be down for
indefinite time.
My configured alert looks like this:
- alert: Network-Interface-Down
expr: node_network_up{device!~"lo.*"} * on(instance)
group_left(nodename) node_uname_info * on(instance,device)
group_left(address) node_network_info == 0
for: 5m
labels:
severity: "CRITICAL"
annotations:
summary: "Network interface down - {{ $labels.device }} on {{
$labels.nodename }}"
I want to disable the alert for eth1 on Host1, eth5,8 on Host2.
