Hello Friends,
I would like to knw the query for node/host reboot alerts for alert manager.
I had used one query which is giving wrong alerts, which is not matching
the need.
changes(node_boot_time_seconds{job="kubernetes-service-endpoints"} [1h])*
on(instance) group_left(nodename)
group(node_uname_info{})by(instance,nodename)>0
or
changes(node_boot_time_seconds{job="kubernetes-service-endpoints"} [1h])
Can you please suggest us better way of query to get reboot alert.
Thanks
