Hi List! New try.
I have a problem with rrdtool update. I have update in my c-program. If I start the c-program on my self then write update my data in rrd. When I start my c-program with crontab, than do update no write in rrd. My rrd have the topical time-data but no modem-data. Thx David #---------- Code --------------------------- # name = "/home/user/699.rrd" data = "699:11:22:33:44:55:66:77" void db_fuellen(char *name, char *daten) { char *update; int err = 0; asprintf(&update,"rrdtool update %s N:%s",name,daten); err = system(update); free(update); } _______________________________________________ rrd-users mailing list rrd-users@lists.oetiker.ch https://lists.oetiker.ch/cgi-bin/listinfo/rrd-users
