Dapper, A Large-Scale Distributed Systems Tracing Infrastructure
Modern Internet services are often implemented as complex, large-scale distributed systems. These applications are constructed from collections of software modules that may be developed by different teams, perhaps in different programming languages, and could span many thousands of machines across multiple physical facilities. Tools that aid in understanding system behavior and reasoning about performance issues are invaluable in such an environment. Here the author introduces the design of Dapper, Google's production distributed systems tracing infrastructure, and describe how the design goals of low overhead, application-level transparency, and ubiquitous deployment on a very large scale system were met.
