apache graph: UPDATE

Hi,

The apache server is listening on port 7792 and I forgot to add ?auto to the 
url in bb-hosts.  But only the TA and TKB counters are updated.  I have the 
same problem on a linux box (apache 2)

rrdtool info apache.rrd | grep last_ds
ds[TA].last_ds = "5257984"
ds[TKB].last_ds = "15938577"
ds[BW].last_ds = "UNKN"
ds[IW].last_ds = "UNKN"
ds[CPU].last_ds = "UNKN"
ds[REQPERSEC].last_ds = "UNKN"

This is the server-status page:
Total Accesses: 5258069
Total kBytes: 15939014
CPULoad: .00565547
Uptime: 7100739
ReqPerSec: .740496
