Methods

#base_ejection_time

def base_ejection_time() -> ::Google::Cloud::Compute::V1::Duration

Returns

• (::Google::Cloud::Compute::V1::Duration) — The base time that a backend endpoint is ejected for. Defaults to 30000ms or 30s. After a backend endpoint is returned back to the load balancing pool, it can be ejected again in another ejection analysis. Thus, the total ejection time is equal to the base ejection time multiplied by the number of times the backend endpoint has been ejected. Defaults to 30000ms or 30s.

#base_ejection_time=

def base_ejection_time=(value) -> ::Google::Cloud::Compute::V1::Duration

Parameter

• value (::Google::Cloud::Compute::V1::Duration) — The base time that a backend endpoint is ejected for. Defaults to 30000ms or 30s. After a backend endpoint is returned back to the load balancing pool, it can be ejected again in another ejection analysis. Thus, the total ejection time is equal to the base ejection time multiplied by the number of times the backend endpoint has been ejected. Defaults to 30000ms or 30s.
