im not sure if this is the right forum to posts this in, so move if its not.

how good is cpanel3 at loging bandwidth used?

should i trust cpanel3 saying that my site use around a 1GB of bandwidth or should i trust Analog saying my site uses 17GB of bandwidth?

have you looked closely at the date range of the stats? I know I have analog going out to one year of archived logs and analyzing them.

You might be looking at a vastly different range, 1 months (maybe one week), to possibly months on analog
