There's a utility that I found years ago called LogMon that gives you real time scrolling logs with the ability to scroll back and forth (and left and right).
Additionally, you can monitor multiple log files on one screen, again with full scrolling capability.
This utility is always the first thing I install on every Linux server I touch as it makes short work of managing log files. It is a tool that should be in every Linux administrator's tool kit.
