Question about hobbitd_rrd

All,

I am trying to find out if I change settings hobbitd_rrd.c

From

            newrec->key = strdup("");

            newrec->defs = (char **)malloc(4 * sizeof(char *));;

            newrec->defs[0] = strdup("RRA:AVERAGE:0.5:1:576");

            newrec->defs[1] = strdup("RRA:AVERAGE:0.5:6:3456");

            newrec->defs[2] = strdup("RRA:AVERAGE:0.5:24:13824");

            newrec->defs[3] = strdup("RRA:AVERAGE:0.5:288:27648");

            newrec->count = 4;

            rbtInsert(rrddeftree, newrec->key, newrec);

To

            newrec->key = strdup("");

            newrec->defs = (char **)malloc(4 * sizeof(char *));;

            newrec->defs[0] = strdup("RRA:AVERAGE:0.5:1:576");

            newrec->defs[1] = strdup("RRA:AVERAGE:0.5:6:27648");

            newrec->defs[2] = strdup("RRA:AVERAGE:0.5:24:27648");

            newrec->defs[3] = strdup("RRA:AVERAGE:0.5:288:27648");

            newrec->count = 4;

            rbtInsert(rrddeftree, newrec->key, newrec);

and recompile.

Does this only affect new created files with xymon or will it start giving me error messages on the previously created rrd files?

Thank you,

Tom
