Hi,
this status mean - hostname(s) not resolved
during polling process.
As example, when your DNS server not
respond, stopped working as an user written here.

I can see in my observium
installation
that many devices changed their status to down(dns).
This is a new installation and we
migrated
the configuration yesterday on a new server and devices were working
properly.
At around the same time (14:20:00) a
lot of our machines changed their status to down.
The message in the Event log is
"Device
status changed to Down (dns)". I tried to find what the problem may
be but I can see SNMP are correct and dns records exist for the systems.
Any ideas?
Thank you,
Marios
