Re: [Nagios-users] Check_Ping plugin not Incrementing Check Attempt Value

It looks like you use parent-child-relationships? That would explain why it's written "Host Unreachable (172.21.10.170) " instead of Host Down. Was the parent of this host down as well? In this case, Nagios 'knows' that it doesn't make sense to continue checks on the child hosts. On Mon, Jan 30, 2012 at 7:24 PM, Robert V.
