    HTTP Faults

    At least one of the following Faults should be specified.

    Abort

    • httpStatus - HTTP status code which will be returned to source side
    • percentage - percentage of requests on which abort will be injected, has to be in [0.0 - 100.0] range

    Delay

    Delay defines configuration of delaying a response from a destination.

    • value - the duration during which the response will be delayed
    • percentage - percentage of requests on which delay will be injected, has to be in [0.0 - 100.0] range

    ResponseBandwidth limit

    ResponseBandwidth defines a configuration to limit the speed of responding to the requests.

    • limit - represented by value measure in gbps, mbps, kbps or bps, e.g. 10kbps
    • percentage - percentage of requests on which response bandwidth limit will be injected, has to be in [0.0 - 100.0] range
