STRIDER: A Black-box, State-based Approach to Change and Configuration Management and Support Yi-Min Wang, Chad Verbowski, John Dunagan, Yu Chen, Helen J. Wang, Chun Yuan, and Zheng Zhang, Microsoft Research
We describe a new approach, called Strider, to Change and
Configuration Management and Support (CCMS). Strider is a black-box
approach: without relying on specifications, it uses state
differencing to identify potential causes of differing program
behaviors, uses state tracing to identify actual, run-time state
dependencies, and uses statistical behavior modeling for noise
filtering. Strider is a state-based approach: instead of linking
vague, high-level descriptions and symptoms to relevant actions, it
models management and support problems in terms of individual, named
pieces of low-level configuration state and provides precise mappings
to user-friendly information through a computer genomics database. We
use troubleshooting of configuration failures to demonstrate that the
Strider approach reduces problem complexity by several orders of
magnitude, making root cause analysis possible.
