Method: regionHealthCheckServices.list

Lists all the HealthCheckService resources that have been configured for the specified project in the given region.

HTTP request

GET https://compute.googleapis.com/compute/beta/projects/{project}/regions/{region}/healthCheckServices

The URL uses gRPC Transcoding syntax.

Path parameters

Parameters
project

string

Project ID for this request.
region

string

Name of the region scoping this request.

Query parameters

Parameters
maxResults

integer (uint32 format)

The maximum number of results per page that should be returned. If the number of available results is larger than maxResults, Compute Engine returns a nextPageToken that can be used to get the next page of results in subsequent list requests. Acceptable values are 0 to 500, inclusive. (Default: 500)
pageToken

string

Specifies a page token to use. Set pageToken to the nextPageToken returned by a previous list request to get the next page of results.
filter

string

A filter expression that filters resources listed in the response. Most Compute resources support two types of filter expressions: expressions that support regular expressions and expressions that follow API improvement proposal AIP-160. These two types of filter expressions cannot be mixed in one request.

If you want to use AIP-160, your expression must specify the field name, an operator, and the value that you want to use for filtering. The value must be a string, a number, or a boolean. The operator must be either =, !=, >, <, <=, >= or :.

For example, if you are filtering Compute Engine instances, you can exclude instances named example-instance by specifying name != example-instance.

The :* comparison can be used to test whether a key has been defined. For example, to find all objects with owner label use:

labels.owner:*

You can also filter nested fields. For example, you could specify scheduling.automaticRestart = false to include instances only if they are not scheduled for automatic restarts. You can use filtering on nested fields to filter based on resource labels.

To filter on multiple expressions, provide each separate expression within parentheses. For example:

(scheduling.automaticRestart = true)
(cpuPlatform = "Intel Skylake")

By default, each expression is an AND expression. However, you can include AND and OR expressions explicitly. For example:

(cpuPlatform = "Intel Skylake") OR
(cpuPlatform = "Intel Broadwell") AND
(scheduling.automaticRestart = true)

If you want to use a regular expression, use the eq (equal) or ne (not equal) operator against a single un-parenthesized expression with or without quotes or against multiple parenthesized expressions. Examples:

fieldname eq unquoted literal fieldname eq 'single quoted literal' fieldname eq "double quoted literal" (fieldname1 eq literal) (fieldname2 ne "literal")

The literal value is interpreted as a regular expression using Google RE2 library syntax. The literal value must match the entire field.

For example, to filter for instances that do not end with name "instance", you would use name ne .*instance.

You cannot combine constraints on multiple fields using regular expressions.
orderBy

string

Sorts list results by a certain order. By default, results are returned in alphanumerical order based on the resource name.

You can also sort results in descending order based on the creation timestamp using orderBy="creationTimestamp desc". This sorts results based on the creationTimestamp field in reverse chronological order (newest result first). Use this to sort resources like operations so that the newest operation is returned first.

Currently, only sorting by name or creationTimestamp desc is supported.
returnPartialSuccess

boolean

Opt-in for partial success behavior which provides partial results in case of failure. The default value is false.

For example, when partial success behavior is enabled, aggregatedList for a single zone scope either returns all resources in the zone or no resources, with an error code.

Request body

The request body must be empty.

Response body

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

Fields
kind

string

[Output Only] Type of the resource. Always compute#healthCheckServicesList for lists of HealthCheckServices.
id

string

[Output Only] Unique identifier for the resource; defined by the server.
items[]

object

A list of HealthCheckService resources.
items[].kind

string

[Output only] Type of the resource. Always compute#healthCheckServicefor health check services.
items[].id

string (uint64 format)

[Output Only] The unique identifier for the resource. This identifier is defined by the server.
items[].creationTimestamp

string

[Output Only] Creation timestamp in RFC3339 text format.
items[].selfLink

string

[Output Only] Server-defined URL for the resource.
items[].name

string

Name of the resource. 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.
items[].description

string

An optional description of this resource. Provide this property when you create the resource.
items[].region

string

[Output Only] URL of the region where the health check service resides. This field is not applicable to global health check services. You must specify this field as part of the HTTP request URL. It is not settable as a field in the request body.
items[].healthStatusAggregationStrategy
(deprecated)

enum

This field is deprecated. Use healthStatusAggregationPolicy instead.

Policy for how the results from multiple health checks for the same endpoint are aggregated.

  • NO_AGGREGATION. An EndpointHealth message is returned for each backend in the health check service.
  • AND. If any backend's health check reports UNHEALTHY, then UNHEALTHY is the HealthState of the entire health check service. If all backend's are healthy, the HealthState of the health check service is HEALTHY.
.
items[].healthStatusAggregationPolicy

enum

Optional. Policy for how the results from multiple health checks for the same endpoint are aggregated. Defaults to NO_AGGREGATION if unspecified.

  • NO_AGGREGATION. An EndpointHealth message is returned for each <endpoint, health check> pair in the health check service.
  • AND. If any health check of an endpoint reports UNHEALTHY, then UNHEALTHY is the HealthState of the endpoint. If all health checks report HEALTHY, the HealthState of the endpoint is HEALTHY.
. This is only allowed with regional HealthCheckService.
items[].healthChecks[]

string

A list of URLs to the HealthCheck resources. Must have at least one HealthCheck, and not more than 10 for regional HealthCheckService, and not more than 1 for global HealthCheckService. HealthCheck resources must have portSpecification=USE_SERVING_PORT or portSpecification=USE_FIXED_PORT. For regional HealthCheckService, the HealthCheck must be regional and in the same region. For global HealthCheckService, HealthCheck must be global. Mix of regional and global HealthChecks is not supported. Multiple regional HealthChecks must belong to the same region. Regional HealthChecks must belong to the same region as zones of NetworkEndpointGroups. For global HealthCheckService using global INTERNET_IP_PORT NetworkEndpointGroups, the global HealthChecks must specify sourceRegions, and HealthChecks that specify sourceRegions can only be used with global INTERNET_IP_PORT NetworkEndpointGroups.
items[].networkEndpointGroups[]

string

A list of URLs to the NetworkEndpointGroup resources. Must not have more than 100. For regional HealthCheckService, NEGs must be in zones in the region of the HealthCheckService. For global HealthCheckServices, the NetworkEndpointGroups must be global INTERNET_IP_PORT.
items[].notificationEndpoints[]

string

A list of URLs to the NotificationEndpoint resources. Must not have more than 10. A list of endpoints for receiving notifications of change in health status. For regional HealthCheckService, NotificationEndpoint must be regional and in the same region. For global HealthCheckService, NotificationEndpoint must be global.
items[].fingerprint

string (bytes format)

Fingerprint of this resource. A hash of the contents stored in this object. This field is used in optimistic locking. This field will be ignored when inserting a HealthCheckService. An up-to-date fingerprint must be provided in order to patch/update the HealthCheckService; Otherwise, the request will fail with error 412 conditionNotMet. To see the latest fingerprint, make a get() request to retrieve the HealthCheckService.

A base64-encoded string.
nextPageToken

string

[Output Only] This token allows you to get the next page of results for list requests. If the number of results is larger than maxResults, use the nextPageToken as a value for the query parameter pageToken in the next list request. Subsequent list requests will have their own nextPageToken to continue paging through the results.
warning

object

[Output Only] Informational warning message.
warning.code

enum

[Output Only] A warning code, if applicable. For example, Compute Engine returns NO_RESULTS_ON_PAGE if there are no results in the response.
warning.message

string

warning.data[]

object

[Output Only] Metadata about this warning in key: value format. For example: 

"data": [  {  "key": "scope",  "value": "zones/us-east1-d"  }
warning.data[].key

string

[Output Only] A key that provides more detail on the warning being returned. 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).
