There are few solutions:
1. tail + watch commands:

$ watch -n 1 tail -n 10 path/to/log/file

Note: to end watching press ctrl^c (ctrl+c)

Where:

-n 1 causes refreshing once per second
-n 10 causes reading 10 last lines from file

2. less command

$ less +F path/to/file

Note: to end watching press ctrl^c (ctrl+c); to exit less program press q key.

It is possible to enable following for opened less program by pressing shift+f keys.
