Machines that come back on their own after a restart
When a server restarts unexpectedly, KLYRN VM starts again every machine that was running, checks each one booted, and tells you if one did not.
A server can restart when nobody planned it, after a power cut or a provider reset. When it comes back, KLYRN VM starts every machine that was running before.
Only the ones that were running
A machine your customer had shut down stays off. KLYRN starts the ones the restart stopped.
Checked after the start
A minute and a half later KLYRN looks again. If a machine did not boot, it is turned off and started once more. If that does not help, you get an alert with the machine's name.
The features page lists what else KLYRN VM looks after.
