Thanks. It's looking like rrd is not the right tool for this job after all. I can't predict how frequently the different fields in the database will be updated. I just wanted to keep track of the changes but in a round robin fashion so I can see if they are going up, down, or staying still and if they are moving try and get a sense of "velocity". Some items might never change, some might change once a week or day, others might change every ten minutes or so. What's worse field X for one record might change rarely but for another record change all the time. _______________________________________________ rrd-users mailing list [email protected] https://lists.oetiker.ch/cgi-bin/listinfo/rrd-users
