If you use the most recent code in CVS head, you can set a repository wide attributes such has the server hostname once and for all when you configure log4j (using JoranConfigrator). For values depending on the request, such as request server name, and remote address, these should be set using the MDC. In any case, the values you set on the repository wide level and/or the MDC level are merged together when the event is finally output. This was discussed a while ago.
Unfortunately I am unable to find a trace of this discussion in the mailing list archives either because it's there but I can't find it or maybe because it was held privately between Scott and myself. In conclusion, we should hold technical discussions on the log4j-dev list unless there is a good reason to hold them privately.

In our environment, we store the server hostname in the MDC.
First, we put the server hostname in a static variable:
static private final String strServerHostname = getServerHostname();
For each HTTP request, we execute this code:
MDC.put(SERVER_HOSTNAME_KEY, strServerHostname); MDC.put(REQUEST_SERVER_NAME_KEY, req.getServerName()); MDC.put(REQUEST_REMOTE_ADDRESS_KEY, req.getRemoteAddr());
