getBaseEjectionTime()

public Duration getBaseEjectionTime()

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.

Returns
Type Description
Duration

The baseEjectionTime.

getBaseEjectionTimeOrBuilder()

public DurationOrBuilder getBaseEjectionTimeOrBuilder()

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.

getInterval()

public Duration getInterval()

Time interval between ejection analysis sweeps. This can result in both new ejections and backend endpoints being returned to service. The interval is equal to the number of seconds as defined in outlierDetection.interval.seconds plus the number of nanoseconds as defined in outlierDetection.interval.nanos. Defaults to 1 second.

optional .google.cloud.compute.v1.Duration interval = 33547461;

Returns
Type Description
Duration

The interval.

getIntervalOrBuilder()

public DurationOrBuilder getIntervalOrBuilder()

getSuccessRateMinimumHosts()

public int getSuccessRateMinimumHosts()

The number of backend endpoints in the load balancing pool that must have enough request volume to detect success rate outliers.

Returns
Type Description

getSuccessRateRequestVolume()

public int getSuccessRateRequestVolume()

Returns
Type Description
