glTail.rb - http://www.fudgie.org I know, horrible code and global variables, and what not. But, it works, and it's too fun to watch my servers traffic in real time to clean up everything before releasing it. Configuration: Open config.yaml.example in a text editor, and tweak to your liking. Save to *.yaml. Either include a password for each of your servers, or make sure your ssh-keys are correctly set up. If you need to specify a SSH key replace password: secret with keys: /path/to/key Running: ./gl_tail.rb --help ./gl_tail.rb <config.yaml> You can also press 'f' while running to toggle the attempted frames per second. Or 'b' to change default blob type, and space to toggle bouncing.
