Apache graphs broken (NAN)

Hiya people,

OK. So I have managed to break (part) of my hobbit install. The 

background is as follows.

I have a host (say host.org) and it used to monitor a website (www.host.org) and used the apache check (apache=http://www.host.org/server-status?auto) to generate the apache graphs. This host was also running various other websites using virtual hosts.

Anyway, I moved the www.host.org site from the host.org machine and wanted to monitor the host.org site (no www). So I changed the entry in bb-hosts. and restarted. The apache graphs have since stopped updating. I have tried removing the rrd file, removeing the .chk files in tmp (both when hobbit was stoppped)

I guess there must be something I am missing here; can anyone point out what it is?

Cheers

PS. Nothing in the hobbit logs
