Loggin in RT

Hi,

How can I log every operations happening in background in RT? Right now I
get only the logs of the cleaned up sessions which I would be doing once a
month. Nothing more than that.

Also is there a way to have a persistant log file so that even if you
restart the web server the log file wont terminate in between . i.e, when I
refer the apache.error file I get the following entries.

After this I cleaned up the old sessions of RT and then RT logging starts
fine. Is there way to combine these events in RT log instead of apache.error
file?

Thanks
