You seem to be debugging under the assumption that your problem is that the collector gmond isn't getting the metrics from the other gmond, but you haven't given us information to indicate that you've verified that. So: - Can you look at the XML from your collector node (tcp port 8649) and check if it's actually missing the metrics? - Is your gmetad polling the correct collector nodes? - If so, check logfiles and config for gmetad to look for problems storing the data to disk. Check syslog on that host, etc. -- Cos ------------------------------------------------------------------------------ _______________________________________________ Ganglia-general mailing list [email protected] https://lists.sourceforge.net/lists/listinfo/ganglia-general
