Also you cannot have single node rolled up into more than one "cluster." Clusters are defined purely by whatever the final gmond reports to gmetad. So individual nodes must all belong to a single cluster per sender/receiver config, so if for instance I have a cluster of UNIXHOSTS, and some of those are WEBHOSTS, DBHOSTS, MAILHOSTS, etc... You incur the duplication of network complexity and bandwidth in order (and RRDs and I/O if you use gmetad as well) to allow a node to participate in more than one of those clusters. Being able to arbitrarily tag nodes as members of clusters and then having gmetad smartly handle aggregate graphs driven one those tags would be a huge improvement. -Dave ------------------------------------------------------------------------------ Get your SQL database under version control now!
