adding a new configuration option would be the easiest way to prevent any backward incompatible change which will then force this feature to be 3.2+ only. > My goal is to allow different sets of RRAs for different sources, while > making sure the existing file format remains valid. why do you want to have this? what is the use case for having different metric storage frequencies per cluster and why can't be done by having instead independent gmetad? if you are talking about different metric storage frequencies per metric as it seems to be implied later (and which is a feature long in the "wishlist") then wouldn't be safe to assume you want that storage for that metric regardless of source?, if that is the case it will simplify the implementation and will only require something like "RRAs_template" as shown in "d" and not need "a", "b", or "c" at all (or at least not as part of the first implementation). currently in "data_source" the polling interval is optional and so the same could be done with the template to apply in the long run, but complicating the configuration parser, for IMHO no really good reason. using a script is definitely interesting because of the flexibility it allows for, but as mentioned before a problem because of the additional forking required and also problematic because it will keep part of the logic outside gmetad.
