Distributed systems represent some of the most interesting and successful computing applications in use today, from modern web applications and social networks, to data analytics and large-scale machine learning.  However, it is notoriously difficult to understand, troubleshoot, and enforce distributed systems behaviors, because unlike standalone programs, they lack a central point of visibility and control.  This impacts important tasks like resource management, performance, security, accounting, and more.  In this talk I will outline techniques and abstractions for re-establishing cross-component visibility and control.  I will demonstrate with two cross-cutting tools that I have developed in my research: Retro, which measures resource usage and co-ordinates scheduler parameters to achieve end-to-end performance goals; and Pivot Tracing, which dynamically monitors and correlates metrics across component boundaries.  Together, these tools illustrate some of the common challenges and potential solutions when developing and deploying tools for distributed systems.
