QUESTION
I need to set up the circuit break policy so that it would break the circuit only for some specific requests.
I have a sort of a gateway A calling API B which in turn calls C or D. I'm setting up a circuit breaker policy in A. Initial request arriving on A has a parameter that is later used to decide whether to call C or D, lets say http://gateway.A.com?usageParam=C. I'd like to have circuit breaker configured in such a way, that circuit could be open separately for C and D. I mean that if D is failing, calls with usageParam=D should fail immediately but usageParam=C should still go fine and vice versa.
ANSWER
Answered 2021-Jun-14 at 06:57To put it simple a Circuit Breaker can have only just a single state. One of these: Closed, Open, Half-Open.
You should consider the CB as a proxy. It allows each request to go trough it if the downstream system is considered health. If CB detects transient failure (by examining the responses if any) then it will shortcut the execution by denying all requests.
So, if you want to differentiate the healthiness of C and D downstream systems then you would need two CBs (one for each). That allows you to separately allow or deny outgoing requests against different subsystems.
You can place the two CBs inside service A. Here you can register two named HttpClients which are decorated with different Circuit Breakers:

Answered 2021-Jun-13 at 01:34The first thing to know about jQuery .clone() is that it creates new DOM elements from some existing ones.
That implies the same rules as any other dynamically created elements:
- Do not use
ids - Delegate event handlers
Additionnally, the cloned set of elements cannot be appended multiple places... So, to use it as a templating trick, you have to clone twice. Once on page load (to save them before any change occurs) and once again when appending somewhere.

QUESTION
There is a ActiveMQ queue (QueueA). A service (MyService) subscribes to messages, processes it and sends the message to another ActiveMQ queue (QueueB).
ANSWER
Answered 2021-Jun-01 at 09:43Have a look on the Camel RoutePolicy of type ThrottlingExceptionRoutePolicy which is based on the CircuitBreakerLoadBalancer.
Using this policy should allow you to stop consuming from the endpoint when the circuit is in the open state (to compare with the standard circuit behahiour : bypass the service call, and fallback to another response).

QUESTION
I am building microservices architecture for the first time and despite I have read a lot of articles I am still confused how to correctly implement circuit breaker.
Let's suppose that I have several microservices that call each other. So I implemented circuit breaker into each of them as an request interceptor and it works. But I dont like it.
Firstly each service now needs to hit the fail threshold separately before the breaker open. Secondly I write the same functionality for each service over and over again.
So my first thought was to create circuit breaker as stand alone service but I can not find any pattern describing such a functionality. How it would works? Every service before making request calls circuit breaker service firs if target circuit is closed. If so it sends request and when request is finished then reports back to circuit breaker service whether the request was successful or failed?
Or how should be circuit breaker correctly put into microservices architecture?
...ANSWER
Answered 2021-May-28 at 19:48Secondly I write the same functionality for each service over and over again.
One of ways to address this issue in the world of microservices is (as you correctly noticed) to have this functionality moved away of your service. Circuit breaking is just one element, there is many many more other aspects, related to inter-service communication, that you'd have to take care of, such as: handling retries, failovers, authentication and authorization, tracing, monitoring etc. If you were to handle it in all services separately, you'd end up writing the same code (or configuring various frameworks/plugins) over and over again.
The solution that emerged from that need is a service mesh. You can think of it as a middle-man that intercept all the communication between your services and taking care of all above mentioned aspects. There are various solutions. You can check https://github.com/cncf/landscape to find out what is now "hot" and considered a standard. I'd however recommend you getting familiar with the https://istio.io/latest/about/service-mesh/ as it's really mature and powerful.

I have a turbine server running on openshift 3 and deployed a donet core 3.1 c# microservice using steeltoe 3.0.2 circuit breaker libraries. I can monitor the microservice stream on hystrix dashboard through service stream url (/hystrix/hystrix.stream). What I want to do is to register the microservice hystrix event stream to the turbine server event stream. Does anyone know how to do this? any reference link will be a great help also.

QUESTION
I was reading up the documentation for Istio circuit breaker. I see that for a given interval we can set up a numerical value of consecutive5xxErrors (and check few other settings) for the circuit breaking action to take effect.
I wanted to know if it was possible to somehow do circuit breaking in Istio based on the % of 5xxerrors vs normal connections?
ANSWER
Answered 2021-May-25 at 12:44Following on the documentation that you've already found:
As you can see there are specific fields for the outlierDetection:
consecutiveGatewayErrorsconsecutive5xxErrorsintervalbaseEjectionTimemaxEjectionPercentminHealthPercent
The field that will force the request to not hit particular object is: consecutive5xxErrors.
As also it can be seen in the documentation:
Field Type Description Required consecutive5xxErrors UInt32Value Number of 5xx errors before a host is ejected from the connection pool. When the upstream host is accessed over an opaque TCP connection, connect timeouts, connection error/failure and request failure events qualify as a 5xx error. This feature defaults to 5 but can be disabled by setting the value to 0. No-- Istio.io: Latest: Docs: Reference: Config: Networking: Destination Rule: Outlier Detection
The value for it is flat and cannot be used as a percentage.
I found the feature request on the github page of Istio that I think is referencing the feature that you would like to run:
I'd reckon you could try to use an EnvoyFilter to modify the configuration of Envoy (haven't tested it) as Envoy itself has some fields related to the percentages of failures/successes. The documentation that should help you:
