Mesh Fault Injection

This policy uses a new policy matching algorithm. Do not combine with the now deprecated FaultInjection policy.

MeshFaultInjection lets you configure a list of HTTP faults. They execute in the same order as they were defined.

default:
  http:
    - abort:
        httpStatus: 500
        percentage: "2.5"
      delay:
        value: 5s
        percentage: 5
      responseBandwidth:
        limit: "50Mbps"
        percentage: 50
    - abort:
        httpStatus: 500
        percentage: 10
    - delay:
        value: 5s
        percentage: 5

It’s worth mentioning that percentage of the next filter depends on the percentage of previous ones.

http:
  - abort:
      httpStatus: 500
      percentage: 70
  - abort:
      httpStatus: 503
      percentage: 50

That means that for 70% of requests, it returns 500 and for 50% of the 30% that passed it returns 503.

Abort

Abort defines a configuration of not delivering requests to destination service and replacing the responses from destination data plane by predefined status code.

• httpStatus - HTTP status code returned to the source side, in the [100 - 599] range
• percentage - a percentage of requests on which abort will be injected, has to be in [0.0 - 100.0] range. If the value is a double number, put it in quotes.

Delay

Delay defines a configuration of delaying a response from a destination.

• value - the duration during which the response is delayed
• percentage - a percentage of requests on which abort will be injected, has to be in [0.0 - 100.0] range. If the value is a double number, put it in quotes.

ResponseBandwidth limit

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

• limit - represented by value measure in Gbps, Mbps, kbps, or bps, for example 10kbps
• percentage - a percentage of requests on which abort will be injected, has to be in [0.0 - 100.0] range. If the value is a double number, put it in quotes.
