The backup server sleeps most of the time, so the check was UNKNOWN. check_by_sshmon now runs an optional wake command first; the freshness check uses the wol-sleeper wake command, runs every 24h and retries after 6h so a failure does not wake the server every 30s. nagios on the icinga node may run the waker command as wol.
