Is it perhaps showing up in the gmetad/web by it's IP address in stead of it's hostname? That might indicate a DNS/hostname issue.
Also make sure the newly replaced gmond host is not set to "mute" in the gmond.conf
Telnet from the master to the new host gives an XML document, same as the old one.What I would test is telnet (or nc) from master to _another_ host and make sure that it has metrics from the "new" host.I don't understand that at all. Host A is running gmetad. Host B (gmond) is not getting graphed, even though it sends XML. Hosts C through W are working fine. How would telnet from A to C tell me what's wrong with B?
When using multicast, all other gmond's contain the information of the other gmond's. Since you are using unicast that is not the case here.
Why would host C know anything about host B? Should any gmond host have information about all the other gmond hosts? In any case, the telnet output is the same from B and from C. There is no reference to any hosts in it.Are you using multicast (default) or unicast?\Unicast.
Is the route from gmond host B to gmetad host A set correctly? Perhaps the gmond traffic is getting sent over the wrong interface.
When in doubt I tend to use tcpdump myself to verify the traffic is getting sent.
