Steve's right. Separate RRD's would be the way forward to ensure DS consistency. As a suggestion, why not write something which scrapes these RRD's periodically and collates the last DS value and drops it into a single RRD with multiple DS's…?

For this application, you need to have separate RRD files. You can still make a single graph holding data from multiple files; however since the data are coming in at different points in time, and you cannot add a vector to the RRAs until you have all the elements, you should have one RRD per sample.
