Load the log file, then do "M-x auto-revert-tail-mode"

,----[ C-h f auto-revert-tail-mode RET ]
| auto-revert-tail-mode is an interactive autoloaded Lisp function in `autorevert'.
| (auto-revert-tail-mode &optional arg)
| 
| Toggle reverting tail of buffer when file on disk grows.
| With arg, turn Tail mode on iff arg is positive.
| 
| When Tail mode is enabled, the tail of the file is constantly
| followed, as with the shell command `tail -f'.  This means that
| whenever the file grows on disk (presumably because some
| background process is appending to it from time to time), this is
| reflected in the current buffer.
| 
| You can edit the buffer and turn this mode off and on again as
| you please.  But make sure the background process has stopped
| writing before you save the file!
| 
| Use `auto-revert-mode' for changes other than appends!

If you want to highlight specific things in the log, use hi-lock-mode.

You can highlight regexes with hi-lock-face-phrase-buffer:

,----[ C-h f hi-lock-face-phrase-buffer RET ]
| hi-lock-face-phrase-buffer is an interactive compiled Lisp function in `hi-lock.el'.
| (hi-lock-face-phrase-buffer regexp &optional face)
| 
| Set face of each match of phrase regexp to face.
| 
| Whitespace in regexp converted to arbitrary whitespace and initial
| lower-case letters made case insensitive.

I hope this helps.
