The Ganglia Meta Daemon (gmetad) allows you to merge data from seperate gmond processes together into a single meta-cluster image. All data is stored in RRD and XML format for client applications to browse. The PHP frontend is being developed now and will be released in the coming week(s). A bug fix for the monitoring core has also been released. Version 2.4.0 of the monitoring core occasionally would consider a node dead even though it wasn’t but this was fixed in 2.4.1.
