Take a look at the new metric module interface for Ganglia 3.1. This would allow you to write a module that interfaced with IPMI to collection whatever metrics you want. > 2) running ipmitool from the admin node produces no noticeable impact > on the node, but sadly ganglia doesn't know that the data is coming > from somewhere else, and there doesn't appear to be any way to tell > ganglia (or gmetric for that matter) "hey, send this into the stream > as belong to something else"... i.e. host spoofing. > Gmetric does allow you to spoof. You should be able to collect the metrics on the admin node and then spoof the managed node by including the spoofing parameters.
