Hi Kristy, Ganglia versions 3.0.x & 3.1.x are only compatible at the XML/gmetad level, not at the gmond udp/multicast metric level. See the release notes for version 3.1.0 for more information:
http://ganglia.wiki.sourceforge.net/ganglia_release_notes Perhaps this important note should be kept in the release notes for all 3.1.x versions, just in case someone skips over 3.1.0 when upgrading. ~Jason On Fri, 2008-10-24 at 16:05 -0400, Kristy Kallback-Rose wrote: > [repost with subject line changed, was: 3.1.1 report to] > > > I currently have systems with gmond 3.0.5 reporting to a system with > gmond 3.0.5 and gmetad 3.0.4 (gmetad -V ganglia 3.0.4).
