C# Class Hudl.Mjolnir.Breaker.FailurePercentageCircuitBreaker

Trips when the error percentage rises above a configured threshold percentage. This breaker is modeled after Hystrix's HystrixCircuitBreakerImpl. However, the metrics implementations that drive the breaker are fairly different.

Public Methods

Method	Description
IsAllowing ( ) : bool
MarkSuccess ( long elapsedMillis ) : void	Indicates that a recently-completed operation was successful. If the breaker is tripped and `MarkSuccess()` is called, the breaker will be fixed. The operation's elapsed duration (in milliseconds) is used to ensure the operation being checked began before the breaker was initially tripped.

AllowSingleTest ( ) : bool
CheckAndSetTripped ( ) : bool	Checks to see if the breaker should trip, and trips if it should.
