Chris, I fully agree with your clean and simple comment. Part of Ganglia's real strength is what it doesn't have, rather than what it does. Examples:
- metric data is not written locally on the monitored host - The metric set is fixed in compiled code. - No ability to customise graphs. - No server side database other than the RRD files. They may seem like limitations, but in fact they make Ganglia easier to deploy to production hosts, and ongoing administrative effort is essentially zero. We need to carfully consider "enhancements" so we don't end up destroying its simplicity and ease of use.
