I just tested this and unfortunately does not work as I said it would. Basically since you can only specify one cluster in gmond.conf, the collector gmond end up being wrapped in a single <CLUSTER> even though it is collecting data from multiple gmonds talking to it at different ports. Basically gmond is capable of having multiple receive channels at different ports, we just need to modify it to be able to handle having multiple cluster configurations within a single gmond instance. > I have another related question: since I aggregate all of these services into > one gmetad, my grid shows more than the total number of machines (because a > machine running 2 services shows up in two clusters and so I end up with 5-6 > times the actual number of machines in my Grid numbers).

Ganglia is designed to aggregate data from data sources that are distinct with no overlap. One would need to modify gmetad to support this. You are not the first one to request this feature. Maybe someone will come along and take this task on -- any takers? :) Cheers, Bernard ------------------------------------------------------------------------------ This SF.net Dev2Dev email is sponsored by: Show off your parallel programming skills.
