Field Type Description Default
consecutive5xx .google.protobuf.UInt32Value The number of consecutive 5xx responses or local origin errors that are mapped to 5xx error codes before a consecutive 5xx ejection occurs. Defaults to 5.
interval .google.protobuf.Duration The time interval between ejection analysis sweeps. This can result in both new ejections as well as hosts being returned to service. Defaults to 10000ms or 10s.
baseEjectionTime .google.protobuf.Duration The base time that a host is ejected for. The real time is equal to the base time multiplied by the number of times the host has been ejected. Defaults to 30000ms or 30s.
maxEjectionPercent .google.protobuf.UInt32Value The maximum % of an upstream cluster that can be ejected due to outlier detection. Defaults to 10% but will eject at least one host regardless of the value.
enforcingConsecutive5xx .google.protobuf.UInt32Value The % chance that a host will be actually ejected when an outlier status is detected through consecutive 5xx. This setting can be used to disable ejection or to ramp it up slowly. Defaults to 100.
enforcingSuccessRate .google.protobuf.UInt32Value The % chance that a host will be actually ejected when an outlier status is detected through success rate statistics. This setting can be used to disable ejection or to ramp it up slowly. Defaults to 100.
successRateMinimumHosts .google.protobuf.UInt32Value The number of hosts in a cluster that must have enough request volume to detect success rate outliers. If the number of hosts is less than this setting, outlier detection via success rate statistics is not performed for any host in the cluster. Defaults to 5.
successRateRequestVolume .google.protobuf.UInt32Value The minimum number of total requests that must be collected in one interval (as defined by the interval duration above) to include this host in success rate based outlier detection. If the volume is lower than this setting, outlier detection via success rate statistics is not performed for that host. Defaults to 100.
successRateStdevFactor .google.protobuf.UInt32Value This factor is used to determine the ejection threshold for success rate outlier ejection. The ejection threshold is the difference between the mean success rate, and the product of this factor and the standard deviation of the mean success rate: mean - (stdev * success_rate_stdev_factor). This factor is divided by a thousand to get a double. That is, if the desired factor is 1.9, the runtime value should be 1900. Defaults to 1900.
consecutiveGatewayFailure .google.protobuf.UInt32Value The number of consecutive gateway failures (502, 503, 504 status codes) before a consecutive gateway failure ejection occurs. Defaults to 5.
enforcingConsecutiveGatewayFailure .google.protobuf.UInt32Value The % chance that a host will be actually ejected when an outlier status is detected through consecutive gateway failures. This setting can be used to disable ejection or to ramp it up slowly. Defaults to 0.
splitExternalLocalOriginErrors bool Determines whether to distinguish local origin failures from external errors. If set to true the following configuration parameters are taken into account: :ref:consecutive_local_origin_failure<envoy_api_field_cluster.OutlierDetection.consecutive_local_origin_failure>, :ref:enforcing_consecutive_local_origin_failure<envoy_api_field_cluster.OutlierDetection.enforcing_consecutive_local_origin_failure> and :ref:enforcing_local_origin_success_rate<envoy_api_field_cluster.OutlierDetection.enforcing_local_origin_success_rate>. Defaults to false.
consecutiveLocalOriginFailure .google.protobuf.UInt32Value The number of consecutive locally originated failures before ejection occurs. Defaults to 5. Parameter takes effect only when :ref:split_external_local_origin_errors<envoy_api_field_cluster.OutlierDetection.split_external_local_origin_errors> is set to true.
enforcingConsecutiveLocalOriginFailure .google.protobuf.UInt32Value The % chance that a host will be actually ejected when an outlier status is detected through consecutive locally originated failures. This setting can be used to disable ejection or to ramp it up slowly. Defaults to 100. Parameter takes effect only when :ref:split_external_local_origin_errors<envoy_api_field_cluster.OutlierDetection.split_external_local_origin_errors> is set to true.
enforcingLocalOriginSuccessRate .google.protobuf.UInt32Value The % chance that a host will be actually ejected when an outlier status is detected through success rate statistics for locally originated errors. This setting can be used to disable ejection or to ramp it up slowly. Defaults to 100. Parameter takes effect only when :ref:split_external_local_origin_errors<envoy_api_field_cluster.OutlierDetection.split_external_local_origin_errors> is set to true.
