Hi folks,
I am new to RRD and still trying to wrap my mind around the power of
this excellent tool. I am working on an application to use RRD to store
electricity meter data for a group of homes. I am expecting to create an RRD
file for each home, and it will have a number of RRA's defined for various time
periods.
In addition to displaying the individual house data graphs, I would like to
also create graphs that show aggregated results drawn from the house RRD files.
For example, I might show the combined power draw in watts for the 8 homes
that make up a quadrant of my neighborhood, or show the total power draw from
all 30 homes.
Is there a reasonably-straightforward way to do this in RRD?
Any suggestions will be appreciated.
Thanks,
Jeff
