Hello,
I would like to monitor reboot of the server, when server reboots need to
send alert via alertmanager.
Currently I am using following expression
expr: rate(node_boot_time{job="kubernetes-service-endpoints"} [1h])*
on(instance) group_left(nodename)
group(node_uname_info{})by(instance,nodename)>0 or
rate(node_boot_time{job="kubernetes-service-endpoints"} [1h])>0
But I can see wrong alerts are keep populating in my mail box.
Could you please provide me expression we can use other than what I had
used.
Thanks
DV
