Wow... I didn't know there was an O'Reilly book on Ganglia! I will look into that for sure. Thanks for mentioning it. To answer your questions: 1. deaf and mute are set to 'no'. that must be the default setting since I've never messed with those settings before in all my years of working

I'm still racking my brain with this problem I'm having.  I've even ran 'tcpdump -i any port 8204' on my gmetad server and watched the traffic when I've got two gmond clients sending out multicast packets on port 8204 I can see handshaking between my server and

Being that I work at NASA, I'd rather not put entire files out there with names of hosts and ports and the like. :) My initial post had in it part of the gmond config's. My datasource line in my gmetad.conf file (for this one port) is simply something like this: data_source my_name

Are you afraid that we could see performance data of the Curiosity? :D First of all I would really suggest you read the Monitoring with Ganglia book (2012). It answers many questions and solves major problems. About your issue: 1. How do you set deaf and mute in gmond nodes? 2. How many

I'm curious as of what the correct answer would be, but.. We have similar problem (forgive if not, I just scanned through your email), and some kind of solution was to use different data_source (@gmetad) for each of such issues and give them same cluster { name = } (@gmond). I think this
