TLDR
An attempt is made to solve the problem of location of failures of components in a complex system by means of state estimation using dedicated observer schemes, using a particular scheme of decentralized observers in the case of components, whose interacting signals are all available.About:

Self healing grid architecture for decentralized component-based systems
TL;DR: In this paper, a self-healing and self-optimizing grid architecture can be provided in accordance with the present invention Specifically, the architecture can include a mechanism for detecting component failures, and even degraded component performance within peer components in a hosting service Once a failure has been detected, the detecting peer to undertake remedial action to recreate and redeploy the component in the hosting system.

Paper: A survey of design methods for failure detection in dynamic systems
TL;DR: This paper surveys a number of methods for the detection of abrupt changes in stochastic dynamical systems, focusing on the class of linear systems, but the basic concepts carry over to other classes of systems.
A survey of design methods for failure detection in dynamic systems
TL;DR: A number of methods for detecting abrupt changes (such as failures) in stochastic dynamical systems are surveyed in this paper, where tradeoffs in complexity versus performance are discussed, ranging from the design of specific failure-sensitive filters, to the use of statistical tests on filter innovations, and the development of jump process formulations.

Failure Detection in Dynamic Systems
TL;DR: With the increased automation of a wide range of man-machine systems, a characteristic of skilled human performance that gains increasing importance relates to the operator’s ability to monitor a system under automated control, to ensure that any departures from normal functioning are efficiently and promptly detected.
