"that group" being the collectd maintainer (that'd be me ;-))? I'm afraid that building support for that into, say, collection3 is not (currently) possible, since the server does not have access to the client configuration and duplicating the configuration sounds like the wrong approach to me. Anyway, just recently, somebody asked for an interface to query the threshold configuration. In combination with the (planned / in development) "netcmd" plugin that information could be queried remotely. > In particular, for a dashboard, I'll typically have many graphs of the > same metric for different machines.

Well, I'd either go for drawing lines / areas marking warning and critical thresholds or using an approach similar to how it's done in the "docsis upstream utilization" example in the RRDtool gallery.
