One problem I've been wondering about recently is the scalability of gmetad/rrdtool.
Various events could impact the gmetad server load: - adding more clusters - in this case, the admin can easily decide to add the new cluster on a new gmetad server if the existing server is overloaded - adding more hosts to an existing cluster - in this case the admin may have to move a cluster that is getting too big from one gmetad to another. The RRD files needed to be copied, there may be a gap in the monitoring, etc - adding more metrics on the hosts - similar to the problem above, adding more hosts to a cluster In a particularly large organisation, moving around the RRD files as clusters grow could become quite a chore. Is anyone putting their RRD files on shared storage and/or making other arrangements to load balance between multiple gmetad servers, either for efficiency or fault tolerance? ------------------------------------------------------------------------------ Let Crystal Reports handle the reporting - Free Crystal Reports 2008 30-Day trial.
