Hi Jason. I know that multicasting is a very convenient way of sending data to multiple recipients but I'd like some tighter control. Less network traffic is always preferred and thought of all those nodes (maybe > 100???) multicasting really concerns me. I'd like to designate 'collectors/concentrators' for each cluster and instruct monitored nodes to only send their data to their specific concentrators and nowhere else.
I've tried the mute and deaf modes but my conclusion is that currently the only mechanism for transmitting data from gmond to gmond is multicasts. ---- Yemi > -----Original Message----- > From: Jason A.
