In recent years, configuration errors (ie, misconfigurations) have become one of the
dominant causes of system failures, resulting in many severe service outages and …

Large, production quality distributed systems still fail periodically, and do so sometimes
catastrophically, where most or all users experience an outage or data loss. We present the …

Configuration errors (ie, misconfigurations) are among the dominant causes of system
failures. Their importance has inspired many research efforts on detecting, diagnosing, and …

Troubleshooting the performance of production software is challenging. Most existing tools,
such as profiling, tracing, and logging systems, reveal what events occurred during …

Similar to software bugs, configuration errors are also one of the major causes of today's
system failures. Many configuration issues manifest themselves in ways similar to software …

Performance diagnosis is labor intensive in production cloud computing systems. Such
systems typically face many real-world challenges, which the existing diagnosis techniques …

Software misconfigurations are time-consuming and enormously frustrating to troubleshoot.
In this paper, we show that dynamic information flow analysis helps solve these problems by …

Recently, Bronson et al. introduced a framework for understanding a class of failures in
distributed systems called metastable failures. The examples of metastable failures …

Configuration error injection testing (CEIT) could systematically evaluate software reliability
and diagnosability to runtime configuration errors. This paper explores the challenges and …

As software systems become more complex and configurable, failures due to
misconfigurations are becoming a critical problem. Such failures often have serious …
