Represents possible action applied to upstream host

Used in: OutlierDetectionEvent

• EJECT = 0

  In case host was excluded from service

• UNEJECT = 1

  In case host was brought back into service

[#next-free-field: 12]

• OutlierEjectionType type = 1

  In case of eject represents type of ejection that took place.

• optional google.protobuf.Timestamp timestamp = 2

  Timestamp for event.

• optional google.protobuf.UInt64Value secs_since_last_action = 3

  The time in seconds since the last action (either an ejection or unejection) took place.

• string cluster_name = 4

  The :ref:`cluster <envoy_api_msg_Cluster>` that owns the ejected host.

• string upstream_url = 5

  The URL of the ejected host. E.g., ``tcp://1.2.3.4:80``.

• Action action = 6

  The action that took place.

• uint32 num_ejections = 7

  If ``action`` is ``eject``, specifies the number of times the host has been ejected (local to that Envoy and gets reset if the host gets removed from the upstream cluster for any reason and then re-added).

• bool enforced = 8

  If ``action`` is ``eject``, specifies if the ejection was enforced. ``true`` means the host was ejected. ``false`` means the event was logged but the host was not actually ejected.

• oneof event

  • OutlierEjectSuccessRate eject_success_rate_event = 9

  • OutlierEjectConsecutive eject_consecutive_event = 10

  • OutlierEjectFailurePercentage eject_failure_percentage_event = 11

(message has no fields)

Used in: OutlierDetectionEvent

• uint32 host_success_rate = 1

  Host's success rate at the time of the ejection event on a 0-100 range.

Used in: OutlierDetectionEvent

• uint32 host_success_rate = 1

  Host’s success rate at the time of the ejection event on a 0-100 range.

• uint32 cluster_average_success_rate = 2

  Average success rate of the hosts in the cluster at the time of the ejection event on a 0-100 range.

• uint32 cluster_success_rate_ejection_threshold = 3

  Success rate ejection threshold at the time of the ejection event.

Type of ejection that took place

Used in: OutlierDetectionEvent

• CONSECUTIVE_5XX = 0

  In case upstream host returns certain number of consecutive 5xx. If :ref:`outlier_detection.split_external_local_origin_errors<envoy_api_field_cluster.OutlierDetection.split_external_local_origin_errors>` is *false*, all type of errors are treated as HTTP 5xx errors. See :ref:`Cluster outlier detection <arch_overview_outlier_detection>` documentation for details.

• CONSECUTIVE_GATEWAY_FAILURE = 1

  In case upstream host returns certain number of consecutive gateway errors

• SUCCESS_RATE = 2

  Runs over aggregated success rate statistics from every host in cluster and selects hosts for which ratio of successful replies deviates from other hosts in the cluster. If :ref:`outlier_detection.split_external_local_origin_errors<envoy_api_field_cluster.OutlierDetection.split_external_local_origin_errors>` is *false*, all errors (externally and locally generated) are used to calculate success rate statistics. See :ref:`Cluster outlier detection <arch_overview_outlier_detection>` documentation for details.

• CONSECUTIVE_LOCAL_ORIGIN_FAILURE = 3

  Consecutive local origin failures: Connection failures, resets, timeouts, etc This type of ejection happens only when :ref:`outlier_detection.split_external_local_origin_errors<envoy_api_field_cluster.OutlierDetection.split_external_local_origin_errors>` is set to *true*. See :ref:`Cluster outlier detection <arch_overview_outlier_detection>` documentation for

• SUCCESS_RATE_LOCAL_ORIGIN = 4

  Runs over aggregated success rate statistics for local origin failures for all hosts in the cluster and selects hosts for which success rate deviates from other hosts in the cluster. This type of ejection happens only when :ref:`outlier_detection.split_external_local_origin_errors<envoy_api_field_cluster.OutlierDetection.split_external_local_origin_errors>` is set to *true*. See :ref:`Cluster outlier detection <arch_overview_outlier_detection>` documentation for

• FAILURE_PERCENTAGE = 5

  Runs over aggregated success rate statistics from every host in cluster and selects hosts for which ratio of failed replies is above configured value.

• FAILURE_PERCENTAGE_LOCAL_ORIGIN = 6

  Runs over aggregated success rate statistics for local origin failures from every host in cluster and selects hosts for which ratio of failed replies is above configured value.
