HI Akilan, To catch the calls to load tiles use a osgDB::Registry::ReadFileCallback. There has been plenty of discussion on this on osg-users mailing list so just do a search for ReadFileCallback and you should get lots of hits.
W.r.t notify, you can attach a custom streambuf to capture this stream. I think there may be something on the FAQ about this. Or... if you can update to svn/trunk or OSG-2.9.5 then there is new mechanism for overriding the notify output. Robert.
