Question

I am testing the spring boot chaos monkey with feign ,hystrix and ribbon. It is not working. Calls are not failing as expected.

organizationService:
  ribbon:
    MaxAutoRetries: 2
    MaxAutoRetriesNextServer: 0
    OkToRetryOnAllOperations: true
    ServerListRefreshInterval: 2000
    ConnectTimeout: 10000
    ReadTimeout: 1000

chaos config:

chaos:
    monkey:
        enabled: true
        watcher:
            controller: false
            restController: false
            service: false
            repository: true
            component: true

        assaults:
            level: 1
            latencyActive: true
            latencyRangeStart: 11000
            latencyRangeEnd: 40000
