CircuitBreaker
sources
(required, repeated)List of selectors to match dataplanes that are sources of traffic.
destinations
(required, repeated)List of selectors to match services that are destinations of traffic.
conf
(required)Child properties:
interval
(optional)Time interval between ejection analysis sweeps
baseejectiontime
(optional)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
maxejectionpercent
(optional)The maximum percent of an upstream cluster that can be ejected due to outlier detection, has to be in [0 - 100] range
splitexternalandlocalerrors
(optional)Enables Split Mode in which local and external errors are distinguished
detectors
(optional)Child properties:
totalerrors
(optional)Errors with status code 5xx and locally originated errors, in Split Mode - just errors with status code 5xx
Child properties:
consecutive
(optional)
gatewayerrors
(optional)Subset of ‘total’ related to gateway errors (502, 503 or 504 status code)
Child properties:
consecutive
(optional)
localerrors
(optional)Takes into account only in Split Mode, number of locally originated errors
Child properties:
consecutive
(optional)
standarddeviation
(optional)Child properties:
requestvolume
(optional)Ignore hosts with less number of requests than ‘requestVolume’
minimumhosts
(optional)Won’t count success rate for cluster if number of hosts with required ‘requestVolume’ is less than ‘minimumHosts’
factor
(optional)Resulting threshold = mean - (stdev * factor)
failure
(optional)Child properties:
requestvolume
(optional)Ignore hosts with less number of requests than ‘requestVolume’
minimumhosts
(optional)Won’t count success rate for cluster if number of hosts with required ‘requestVolume’ is less than ‘minimumHosts’
threshold
(optional)Eject host if failure percentage of a given host is greater than or equal to this value, has to be in [0 - 100] range
thresholds
(optional)Child properties:
maxconnections
(optional)The maximum number of connections that Envoy will make to the upstream cluster. If not specified, the default is 1024.
maxpendingrequests
(optional)The maximum number of pending requests that Envoy will allow to the upstream cluster. If not specified, the default is 1024.
maxretries
(optional)The maximum number of parallel retries that Envoy will allow to the upstream cluster. If not specified, the default is 3.
maxrequests
(optional)The maximum number of parallel requests that Envoy will make to the upstream cluster. If not specified, the default is 1024.
