So you didn't find all intervals which contained this particular rate, unless by remote chance you grepped for a timestamp which happened to be n*86400. > Good enough for now, as the graphs changed...

And wrong data is what you now have (most likely). If such changes happen often, then consider the following procedure: Save your updates to a file, including a timestamp (not: "N"). Make backups regularly. For instance do so each day, saving two files: [...] database.rrd.2007-12-23 database.updates.2007-12-23 database.rrd.2007-12-24 database.updates.2007-12-24 database.rrd.2007-12-25 database.updates.2007-12-25 [...] Then consider the backed up RRD as your full backup, and the saved timestamps as incremental backups. Now, if you need to change a value, revert to the backed up RRD and replay your updates (except that wrong update, of course). edit database.updates.2007-12-23 copy database.rrd.2007-12-23 database.rrd rrdtool - < database.updates.2007-12-23 rrdtool - < database.updates.2007-12-24 rrdtool - < database.updates.2007-12-25 If you want this or similar functionality in RRDtool, program it! I'm sure there are programmers who would like to do that job for you. I know Tobi would be interested, as would I. But is it important enough for you to hire a programmer? -- Alex van den Bogaerdt http://www.vandenbogaerdt.nl/rrdtool/ _______________________________________________ rrd-users mailing list [email protected] https://lists.oetiker.ch/cgi-bin/listinfo/rrd-users
