LCM-Spy-Lite is a lightweight terminal-based implementation of LCM-Spy. This tool allows a developer to observe LCM (https://code.google.com/p/lcm) messages in transit for debugging purposes. LCM-Spy-Lite is very useful on emebeded systems where the Java Runtime Environnment and X11-forwarding (as required by LCM-Spy) is prohibitive.
