Hystrix commands give us nice options for how we want the target logic to be invoked. When calls to a particular service exceed circuitBreaker.requestVolumeThreshold (default: 20 requests) and the failure percentage is greater than circuitBreaker.errorThresholdPercentage (default: >50%) in a rolling window defined by metrics.rollingStats.timeInMilliseconds (default: 10 seconds), the circuit opens and the call is not made. 6. Below is an example route showing an Hystrix endpoint that protects against slow operation by falling back to the in-lined fallback route. a simple example below where we specify the number of failed requests that should open the circuit and the retry timeout: 4 1 Should it just trip the circuit breaker if the code times out?

Sure @Nikolas-Charalambidis This is the file that you should change. To subscribe to this RSS feed, copy and paste this URL into your RSS reader. Hystrix is an amazing tool to help stop cascading failure and enable resilience in complex distributed systems. As to why there is a second increase after you set the hystrix timeout, you can debug hystrix's call stack to find out that HystrixRuntimeException isn't being thrown in the same order. Note: There’re more settings besides these two, but a discussion of all of them is beyond the scope of this post.
