}
Fields
percentage

integer

Required. Percentage of requests to delay, in the range 0 to 100, inclusive.
delay

string (Duration format)

Required. Delay duration.

A duration in seconds with up to nine fractional digits, ending with 's'. Example: "3.5s".

GCEFailCompute

GCEFailCompute specifies which instances to fail.
