The 2 servers are not using the same IP. They are tied to each other in
the hobbit configs in that they point to each other.****
** **
My existing hobbit servers, hobbit1 and hobbit2, are the fail-over for each
other. So they have the exact same configuration, and report data to each
other in their client settings. All servers with hobbit or bbwin clients
send data to both servers.****
** **
When I bring the new replacement server online, I shutdown hobbit2, and
have the new server assume it's IP.****
** **
I will try the ping test to see exactly when it stops responding..****
** **
The strangest thing, like I said, is it's the exact same 4 hosts that show
red for CONN. This was with every combination of centos/xymon/hobbit below..
I even cloned one of my existing centos 5 32-bit servers running hobbit 4.2
in another environment (our perimeter network that is firewalled off), such
that the only thing that was different was the linux distro, and that also
caused the same 4 servers to show red..****

Are the two servers using the same IP? Tied to one another in any way? I
would start a ping and turn the other server on and see when it goes down.

I'm having a pretty strange issue. We have our existing hobbit servers
running on Fedora servers running hobbit 4.2.0. I'm working on installing
brand new servers that will be running CentOS 6 64-bit and the latest
version of xymon (4.3.3 before I saw 4.3.4 today). I did not see a fix to my
issue in the 4.3.4 change log though, so figured I'd post here.
In doing my update, I install the brand new server from scratch.
Basically install CentOS 6 as a web server install, and then add in all the
bits xymon needs (pcre, openssl, openldap, rrdtool, etc).. Then I compile
and install xymon to /usr/lib/xymon. Next I copy over the bb-hosts file to
the hosts.cfg, and follow the "migration" steps to get the data and
configuration files over. Then I turn on xymon on the new server.
Within a few minutes, 4 servers turn to red alerts on CONN on the
existing Fedora based Hobbit servers. They begin flapping on and off of red
alert until I shutdown the new CentOS xymon server. Within a few minutes of
the new server being shut down, the alerts go away for good.
I have tried going to Centos 5 32-bit, 64-bit, even trying xymon 4.2.3,
or all the way back to hobbit 4.2.0 all with the same result, and the exact
same 4 servers each time.
I'm completely at a loss here. Does anyone know what may be causing these
issues where the only difference is the OS being used (the distro, that is)?
I just want to get our monitoring server upgraded to a stable OS, with
updates, and get xymon up to date as well.
Thanks,
-Ben
