I’ve rebooted my varnish servers and they’ve changed their IP addresses.
Sensu, as many other apps, is managed via Puppet in my env.
Puppet won’t run unless I tell it so.
So, these varnish servers IP addresses changed, Puppet didn’t run so the IP addresses in client.json didn’t change either, but there’re no warnings or errors in sensu. I mean, doesn’t it have to trigger an alarm if the address don’t match the actual one? How does sensu server identify the nodes? By name?
