Abstract
In one embodiment, a proxying agent loaded at application startup loads a circuit breaker framework into a class loader, and also loads a circuit breaker proxy into an extension class loader seen by the proxying agent and by the application. The proxying agent may also instrument selected methods of the application, such that, when calling to run an instrumented method: an ID of the circuit breaker proxy is set to a trackable context, and the proxy execution may be held until exit of the run method (and if exit of the run method is due to a particular exception, an exception of the proxy may also be set to reflect the particular exception). The circuit breaker may then monitor the proxy for latency, exceptions, and circuit breaker trip criteria, and stops the run method in response to the latency, exceptions, or circuit breaker trip criteria surpassing a particular respective threshold.
