One related issue for me is distributing the load across multiple gmetad servers dynamically - is something like this on the roadmap for either of the gmetad versions? At the moment, the administrator has to manage the load and move things around, but with users feeding their own metrics in, the need for Ganglia to adapt dynamically and distribute the load becomes more important. My first thoughts on the matter involved some kind of shared storage containing all the RRDs, and using DLM to make sure that only one gmetad can write the RRDs for a particular host or cluster. ------------------------------------------------------------------------------ Let Crystal Reports handle the reporting - Free Crystal Reports 2008 30-Day trial.
