    Hi everyone. What is the write way? i have 5 microservices and zull, hava any way to implement hystrix over zuul to protect all services or i have to implement hystrix in any microservice? in your opinion?

    Hello guys wanted to ask you what do you think about SWIM and gossip protocol for microservices faliure detection and cluster membership for example:

    hey, has anyone integrated hystrix metrics to prometheus ?

    Thanks @davidkarlsen , but unfortunately that one is not working for me...any other suggestion?

    how is it not working?

    @sushant91265_twitter
    looks like the metrics I'm getting after hitting http://localhost:8888/metrics are spring-actuator-metrics(http://jsoneditoronline.org/?id=26dbc05242d6f12bba63df3f31ece107) and it is not in the prometheus required format and that is why getting error as "text format parsing error..."

    Hi, I want to implement the Hystrix in gateway(like zuul).
    The gateway will discover service A, B or C, assume the service A has 10 instances and 10 Api. My question is.
    What is the best practice for the command key decision? Service Name+Instance IP+Api Name, it seems this gain the best detail level, as the different api, different instance fail will not circle break the other, But it may occupy large volume of command key.

    Hello. I'm using Hystrix and its circuit breaker. It seems that HTTP 404 error is considered as an error so the circuit gets opened (trapped) after multiple 404 errors. How can I tell Hystrix to consider 404 responses as a success ? (to deal with Restful architecture)

    Why Hystrix fallback not controlled by timeout?
    Mr.CrazyIT
    @dicheng52119
    Is neccessary to save the Hystrix monitoring log information to the database?
    I really want to know there is no need, because my project needs to use it, which God can help me?

    Hi, I am working on a project using Hystrix and gRPC. I have a HystrixObservableCommand class - MemberCommand and I am subscribing using Schedulers.io()

    memberCommand.toObservable().subscribeOn(Schedulers.io());

    In the construct method, I log the gRPC context but it returns null -

    protected Observable<Greeter.GreeterReply> construct() {
 logger.info("0 -- In MemberCommand, traceId from gRPC context = {}", ContextKeys.TRACE_ID_CTX_KEY.get());

    Any ideas, how I can propagate gRPC context through RxIoScheduler threads?
    For the above I get, 

    0 -- In MemberCommand, traceId from gRPC context = null

    I could really use a look at this question regarding testing the hystrix fallback behavior in a Feign client:
    https://stackoverflow.com/questions/48815080/testing-hystrix-fallback-through-feign-api-com-netflix-client-clientexception
    I'm new to this, so I'm probably just missing something simple.

    Hey!! I have wrapped my commands to access datastax under hystix. When I disconnect myself from internet, I sometimes get NoHostAvailable(Wrapped under HystrixRuntimeException) and sometimes I get HystrixTimeout with all the other configurations, even the withExecutionTimeoutInMilliseconds remaining same for both cases.
    Can anyone let me know, why i am getting these two different types of exceptions?

    is there a mechanism to load hystrix configuration from a properties file (or application.yml in a boot app)? In particular I'm using the javanica contrib library.
    two things I've tried: I noticed the log entry: To enable URLs as dynamic configuration sources, define System property archaius.configurationSource.additionalUrls or make config.properties available on class path. and wondered if it would be sufficient to put hystrix properties in config.properties, that seemed to have no effect (config.properties is picked up but the timeout on the thread is not applied). I also tried ConfigurationManager.loadPropertiesFromResources("config.properties") which also seems to have no effect.

    I am trying to override a hystrix command timeout for a feign client from command line. I can't figure out syntax for the # and parens. I'm using spring-boot-2 and spring-cloud-netflix.

    hystrix:
  command:
    FeignClientClass#methodName(ParamsClass):
      execution:
        isolation:
          thread:
            timeoutInMilliseconds: 10000

    set HYSTRIX_COMMAND_FEIGNCLIENTCLASS#METHODNAME(PARAMSCLASS)_EXECUTION_ISOLATION_THREAD_TIMEOUTINMILLISECONDS=10000

    Has anyone got experience with this and some suggestions?

    Hello everyone,
    If I have a service that has around 10 hystrix commands, one per API method call, that might call 1000+ API servers, would it be overkilling to have a thread pool per API server?
