gRPC
A gRPC Fault describes the characteristics of the faults to be injected in the gRPC requests served by a target.
A gRPC fault is described by the following attributes:
Attribute | Type | Description |
---|---|---|
averageDelay | string | average delay added to requests represented as a string (default 0 ) |
delayVariation | string | variation in the injected delay (default 0 ) |
statusMessage | string | message to be returned when an error is injected |
statusCode | number | status to be returned when an error is injected |
errorRate | number | rate of requests that will return an error, represented as a float in the range 0.0 to 1.0 (default 0.0 ) |
exclude | string | comma-separated list of services to be excluded from disruption |
port | number | port on which the requests will be intercepted |
Note
averageDelay
anddelayVariation
are applied to all requests affected by the fault, regardless of the value oferrorRate
.statusCode
is returned only to a fraction of requests defined byerrorRate
.
Example
This example defines a gRPC fault that introduces a delay of 50ms
in all requests and returns a status code 13
in 10%
of the requests.
JavaScript
const fault = {
averageDelay: '50ms',
statusCode: 10,
errorRate: 0.1,
};
