Tools that assist users in understanding the complex workings of distributed systems are an important aid to programmers and scientists. Interactive monitoring and steering tools can provide users with insight into their computations. This thesis describes the PathFinder interactive monitoring and steering system and the problems involved in making the system a viable solution for monitoring and steering distributed applications. These problems include MPI support, an Agent Wizard, and a performance analysis of two agent subsystems and their associated milieu, one implemented in Perl and the other in Java.
