Runtime

health_check.min_interval

Min value for the health checking . 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 interval. 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 as the health check filter will write the remote service cluster into the response.

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

outlier_detection.consecutive_gateway_failure

consecutive_gateway_failure setting in outlier detection

outlier_detection.interval_ms

setting in outlier detection

outlier_detection.base_ejection_time_ms

outlier_detection.max_ejection_percent

max_ejection_percent setting in outlier detection

outlier_detection.enforcing_consecutive_5xx

setting in outlier detection

outlier_detection.enforcing_consecutive_gateway_failure

enforcing_consecutive_gateway_failure setting in outlier detection

outlier_detection.enforcing_success_rate

outlier_detection.success_rate_stdev_factor

success_rate_stdev_factor setting in outlier detection

Sets the percentage. Defaults to 50%.

upstream.use_http2

Whether the cluster utilizes the http2 feature 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.
