Hi, A few months back I mentioned that I'd modified gmond to dynamically discover its cluster peers by using the EC2 API to update the udp send channel configuration. Well, we've been running this in production at the Guardian for more than 3 months and it's been a great success.
I think this would be a very useful addition to the Ganglia agent so I'm submitting the code to a separate branch called "feature/cloud" for review and feedback. Changes to gmond.c have been kept to a minimum [1] and it's all conditionally compiled using "--enable-cloud" at the moment. The cloud.c code which does most of the work will need to be refactored to move the EC2-specific code into a separate function so that it can be extended to use other (more standards-based) cloud API's that are available. eg. DeltaCloud and CIMI. I've written a wiki page that explains this stuff in more detail here ... https://github.com/ganglia/monitor-core/wiki/EC2-Discovery As I said, feedback (and enhancement requests) very welcome.
