Method: regionHealthChecks.insert

Creates a HealthCheck resource in the specified project using the data included in the request.

HTTP request

POST https://compute.googleapis.com/compute/v1/projects/{project}/regions/{region}/healthChecks

The URL uses gRPC Transcoding syntax.

Path parameters

Parameters

Parameters
`project`	`string` Project ID for this request.
`region`	`string` Name of the region scoping this request.

project

string

Project ID for this request.

region

string

Name of the region scoping this request.

Query parameters

Parameters

Parameters
`requestId`	`string` An optional request ID to identify requests. Specify a unique request ID so that if you must retry your request, the server will know to ignore the request if it has already been completed. For example, consider a situation where you make an initial request and the request times out. If you make the request again with the same request ID, the server can check if original operation with the same request ID was received, and if so, will ignore the second request. This prevents clients from accidentally creating duplicate commitments. The request ID must be a valid UUID with the exception that zero UUID is not supported (`00000000-0000-0000-0000-000000000000`).

requestId

string

An optional request ID to identify requests. Specify a unique request ID so that if you must retry your request, the server will know to ignore the request if it has already been completed.

For example, consider a situation where you make an initial request and the request times out. If you make the request again with the same request ID, the server can check if original operation with the same request ID was received, and if so, will ignore the second request. This prevents clients from accidentally creating duplicate commitments.

The request ID must be a valid UUID with the exception that zero UUID is not supported (00000000-0000-0000-0000-000000000000).

Fields
`kind`	`string` Type of the resource.
`id`	`string (uint64 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. For example, a name that is 1-63 characters long, matches the regular expression `[a-z]([-a-z0-9]*[a-z0-9])?`, and otherwise complies with RFC1035. This regular expression describes a name where the first character is a lowercase letter, and all following characters are a dash, lowercase letter, or digit, except the last character, which isn't 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`, `HTTP2` or `GRPC`. Exactly one of the protocol-specific health check fields must be specified, which must match `type` field.

`tcpHealthCheck.portName`	`string` Not supported.
`tcpHealthCheck.portSpecification`	`enum` Specifies how a port is selected for health checking. Can be one of the following values: `USE_FIXED_PORT`: Specifies a port number explicitly using the `port` field in the health check. Supported by backend services for passthrough load balancers and backend services for proxy load balancers. Not supported by target pools.

For instance group backends, the health check uses the port number determined by looking up the backend service's named port in the instance group's list of named ports.
`tcpHealthCheck.request`	`string` Instructs the health check prober to send this exact ASCII string, up to 1024 bytes in length, after establishing the TCP connection.
`tcpHealthCheck.response`	`string` Creates a content-based TCP health check.

Response body

Represents an Operation resource.

Google Compute Engine has three Operation resources:

You can use an operation resource to manage asynchronous API requests. For more information, read Handling API responses.

Operations can be global, regional or zonal.

For global operations, use the globalOperations resource.
For regional operations, use the regionOperations resource.
For zonal operations, use the zoneOperations resource.

For more information, read Global, Regional, and Zonal Resources.

Note that completed Operation resources have a limited retention period.

If successful, the response body contains data with the following structure:

The error domain is typically the registered service name of the tool or product that generates the error. Example: "pubsub.googleapis.com".

For example, for warnings where there are no results in a list request for a particular zone, this key might be `scope` and the key value might be the zone name. Other examples might be a key indicating a deprecated resource and a suggested replacement, or a warning about invalid network settings (for example, if an instance attempts to perform IP forwarding but is not enabled for IP forwarding).
`warnings[].data[].value`	`string` [Output Only] A warning data value corresponding to the key.
`httpErrorStatusCode`	`integer` [Output Only] If the operation fails, this field contains the HTTP error status code that was returned. For example, a `404` means the resource was not found.

`setCommonInstanceMetadataOperationMetadata.perLocationOperations[].error.details[]`	`object` A list of messages that carry the error details. There is a common set of message types for APIs to use. An object containing fields of an arbitrary type. An additional field `"@type"` contains a URI identifying the type. Example: `{ "id": 1234, "@type": "types.example.com/standard/id" }`.
