Runtime

health_check.min_interval

Min value for the health checking interval. Default value is 0. The health checking interval will be between min_interval and max_interval.

health_check.max_interval

Max value for the health checking . Default value is MAX_INT. The health checking interval will be between min_interval and max_interval.

health_check.verify_cluster

What % of health check requests will be verified against the expected upstream service as the will write the remote service cluster into the response.

See the outlier detection architecture overview for more information on outlier detection. The runtime parameters supported by outlier detection are the same as the , namely:

outlier_detection.consecutive_5xx

consecutive_5XX setting in outlier detection

outlier_detection.consecutive_gateway_failure

setting in outlier detection

outlier_detection.interval_ms

interval_ms setting in outlier detection

outlier_detection.base_ejection_time_ms

outlier_detection.max_ejection_percent

setting in outlier detection

outlier_detection.enforcing_consecutive_5xx

enforcing_consecutive_5xx setting in outlier detection

outlier_detection.enforcing_consecutive_gateway_failure

setting in outlier detection

outlier_detection.enforcing_success_rate

enforcing_success_rate setting in outlier detection

outlier_detection.success_rate_minimum_hosts

setting in outlier detection

outlier_detection.success_rate_request_volume

success_rate_request_volume setting in outlier detection

outlier_detection.success_rate_stdev_factor

setting in outlier detection

Sets the panic threshold percentage. Defaults to 50%.

upstream.use_http2

Whether the cluster utilizes the http2 if configured. Set to 0 to disable HTTP/2 even if the feature is configured. Defaults to enabled.

upstream.zone_routing.enabled

% of requests that will be routed to the same upstream zone. Defaults to 100% of requests.

upstream.zone_routing.min_cluster_size

Minimal size of the upstream cluster for which zone aware routing can be attempted. Default value is 6. If the upstream cluster size is smaller than min_cluster_size zone aware routing will not be performed.
