Great news! Ogma (written in Haskell) is now a recommended tool for monitoring in Space ROS applications.
For info/context: Space ROS is an open-source space robotics framework for developing flight-quality robotic and autonomous space systems, led by Open Robotics and with support from Blue Origin. Space ROS is based on the Robot Operating System, a middleware used in robotics applications. Within NASA, space robots such as the Astrobee, currently in the ISS, use ROS. (Disclaimer: Ogma is not currently being used in the Astrobee.)
