Early detection is the key to minimizing failure damage induced by configuration errors,
especially those errors in configurations that control failure handling and fault tolerance …

Software failures due to configuration errors are commonplace as computer systems
continue to grow larger and more complex. Troubleshooting these configuration errors is a …

Large-scale cloud services deploy hundreds of configuration changes to production systems
daily. At such velocity, configuration changes have inevitably become prevalent causes of …

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

Partial failures occur frequently in cloud systems and can cause serious damage including
inconsistency and data loss. Unfortunately, these failures are not well understood. Nor can …

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

When systems fail in the field, logged error or warning messages are frequently the only
evidence available for assessing and diagnosing the underlying cause. Consequently, the …

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 …

We present a novel method for diagnosing configuration management errors. Our proposed
approach deduces the state of a buggy computer by running predicates that test system …

Future microprocessors need low-cost solutions for reliable operation in the presence of
failure-prone devices. A promising approach is to detect hardware faults by deploying low …
