However the Perl RRD bindings actually got a function to do that and there are several suggestions to dump the rrd file to xml, change that file and recreate the rrd file but I'm not sure if this is a really good idea... That's one reason (apart from simplicity) why i only used one data source for now. It would be also possible to use a dedicated directory and create RRDs of new counters on-the-fly. I'll have a look at the Perl api, although I don't like Perl that much... ;-) > > It would be great if someone could post some sample data to do some > > tests. > > I cannot send you the full hlr.sqlite3 of my test machine, sorry. but I've > attached the output of 'sqlite3 -csv hlr.sqlite3 "select * from > counters;"'.
