I would guess that it's possibly related to state changes. I think the classification of down vs. unreachable only happens upon state changes. States can be OK (up) or non-OK (down or unreachable)
The child host (down) is in a non-OK state. When its parent goes into non-OK (down) , the child was already non-OK (down), therefore doesn't reclassify to a different non-OK (unreachable). I would agreee that it seems more logical to that only the topmost branch during an outage should be considered Down, and all child nodes to be considered Unreachable. > -----Original Message----- > From: Morris, Patrick [mailto:[EMAIL PROTECTED] > Sent: Friday, August 11, 2006 4:33 PM > To: Brian McKee; Nagios-users@lists.sourceforge.net > Subject: Re: [Nagios-users] Help rephrasing my question > > > > I posted a query on this list a week ago which no-one > responded to. > > https://sourceforge.net/mailarchive/forum.php?thread_id=295006 > > 09&forum_id=1873 > > > > That was a rephrased form of a question I asked a few > > weeks earlier than that > > https://sourceforge.net/mailarchive/forum.php?thread_id=255356 > > 73&forum_id=1873 > > > > I'd appreciate if anyone has a minute to review those > > questions and suggest how I might either determine a > > resolution on my own, or rephase the issue such that someone > > here can contribute a solution. > > > > I did think at the time that I provided enough information, > and I have > > attempted to resolve the issue on my own.
