Resource: HealthCheck

Represents a Health Check resource.

Google Compute Engine has two Health Check resources:

Internal HTTP(S) load balancers must use regional health checks. Internal TCP/UDP load balancers can use either regional or global health checks. All other types of GCP load balancers and managed instance group auto-healing must use global health checks. For more information, read Health Check Concepts.

To perform health checks on network load balancers, you must use either httpHealthChecks or httpsHealthChecks.

Fields
`id`	`string (fixed64 format)` [Output Only] The unique identifier for the resource. This identifier is defined by the server.
`creationTimestamp`	`string` [Output Only] Creation timestamp in 3339 text format.
`name`	`string` Name of the resource. Provided by the client when the resource is created. The name must be 1-63 characters long, and comply with RFC1035. Specifically, the name must be 1-63 characters long and match the regular expression `[a-z]([-a-z0-9]*[a-z0-9])?` which means the first character must be a lowercase letter, and all following characters must be a dash, lowercase letter, or digit, except the last character, which cannot be a dash.
`description`	`string` An optional description of this resource. Provide this property when you create the resource.
`checkIntervalSec`	`integer` How often (in seconds) to send a health check. The default value is 5 seconds.
`timeoutSec`	`integer` How long (in seconds) to wait before claiming failure. The default value is 5 seconds. It is invalid for `timeoutSec` to have greater value than `checkIntervalSec`.
`unhealthyThreshold`	`integer` A so-far healthy instance will be marked unhealthy after this many consecutive failures. The default value is 2.
`healthyThreshold`	`integer` A so-far unhealthy instance will be marked healthy after this many consecutive successes. The default value is 2.
`type`	`enum` Specifies the type of the healthCheck, either `TCP`, `SSL`, `HTTP`, `HTTPS` or `HTTP2`. If not specified, the default is `TCP`. Exactly one of the protocol-specific health check field must be specified, which must match `type` field.
`tcpHealthCheck`	`object`

If not specified, gRPC health check follows behavior specified in `port` and `portName` fields.
`grpcHealthCheck.grpcServiceName`	`string` The gRPC service name for the health check. This field is optional. The value of grpcServiceName has the following meanings by convention: - Empty serviceName means the overall status of all services at the backend. - Non-empty serviceName means the health of that gRPC service, as defined by the owner of the service.
