Eureka. Ok so I have made strides on my own after your response and the new OSX release. (thanks!)
I am able to consolidate the clusters into one and view via X11 firefox both of their data. (yay!) I can also view one of the clusters from my mac, using the newest release today of ganglia (intel btw). I can only see the physical view though, and despite editing my local gmond / gmetad .conf files just like I had between clusters, using ip addresses etc. what I can't find is a way to restart the services because it says: no such services. how do I start them, and does using xampp somehow make it a problem? Any help is very appreciated! Fernanda On Sep 26, 2007, at 2:00 PM, Fernanda Foertter wrote: > Hey Carlos, > > Ok.
