Thanks for the suggestions. Reconfig'd for unicast which fixed the nodes that were reporting down.
I was also getting a: "ERROR: This RRD was created on other architecture" in my httpd log. rrdtools was built into an NFS share and I was running it from a diff machine than it was compiled on, but the arch was the same - kernel versions slighly different, but other than that they are basically the same machine. Anyhow moving everything to the machine where rrdtools was built solved the problem with the images not being displayed and the httpd error went away. Thanks again. It all just works.
