%fleet is an Urbit application for monitoring a set of sponsored ships. It is intended to be run on a ship that is providing value-added sponsor services to other running ships. The primary target audience is stars performing planet services, although it should in principle be useful for galaxies performing star services, as well as planets performing moon services.
%fleet initializes by collecting a set of residents on the host ship from Ethereum and Jael. Periodically, it checks to ensure that the set is up to date. Upon each refresh, new residents are added, and former residents are removed from this set. This “refresh” should occur at least once per hour, and even more frequently if performance allows.
%fleet will automatically monitor the uptime of each ship in its set. Similar to ~midden-fabler/ahoy, it will track the amount of time since the last heartbeat from each ship. If the time since last heartbeat exceeds a specified “heartbeat threshold”, %fleet will comman
