Optional healthyThe number of consecutive health checks successes required before considering an unhealthy target healthy. Defaults to 3.
Optional intervalThe approximate amount of time, in seconds, between health checks of an individual target. Minimum value 5 seconds, Maximum value 300 seconds. For lambda target groups, it needs to be greater as the [timeout] of the underlying [lambda]. Default 30 seconds.
Optional matcherThe HTTP codes to use when checking for a successful response from a target. You can specify multiple values (for example, "200,202") or a range of values (for example, "200-299"). Applies to Application Load Balancers only (HTTP/HTTPS), not Network Load Balancers (TCP)
(Required for HTTP/HTTPS ALB) The destination for the health check request.
Optional portThe port to use to connect with the target.
Optional protocolThe protocol to use to connect with the target. Defaults to HTTP. Not applicable when target_type is [lambda].
Optional timeoutThe amount of time, in seconds, during which no response means a failed health check. For Application Load Balancers, the range is 2 to 60 seconds and the default is 5 seconds.
Optional unhealthyThe number of consecutive health check failures required before considering the target unhealthy. Defaults to 3.
Generated using TypeDoc
A Health Check block.
The Health Check parameters you can set vary by the protocol of the Target Group. See http://docs.aws.amazon.com/elasticloadbalancing/latest/APIReference/API_CreateTargetGroup.html for a complete reference. Keep in mind, that health checks produce actual requests to the backend. The underlying function is invoked when target_type is set to lambda.
