Lots of things that should "never" happen start to happen with frightening regularity once you have enough machines. Few of them are worth paging someone.

- dijit 7y agoThose are two extremes. For me, when a machine reports as abnormal it will decommission itself and file a ticket to be looked at, we have enough extra capacity that it’s ok to do this for 5% of compute before we have issues, and we have an alert if it gets close to that. If you’re doing anything other than that then either your machines are abnormal and functioning, which is scary because they’re now in an unknown state- or you’re able to just throw out anything that seems weird, which might also hide issues with the environment.
