### Method Details

`close()`

    Close httplib2 connections.

`delete(project, region, healthCheck, requestId=None, x__xgafv=None)`

    Deletes the specified HealthCheck resource.

    Args:
      project: string, Project ID for this request. (required)
      region: string, Name of the region scoping this request. (required)
      healthCheck: string, Name of the HealthCheck resource to delete. (required)
      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).
      x__xgafv: string, V1 error format.
        Allowed values
          1 - v1 error format
          2 - v2 error format

    Returns:
      An object of the form:

    { # Represents a health check resource.
        #
        # Google Compute Engine has two health check resources:
        #
        # * [Regional](/compute/docs/reference/rest/v1/regionHealthChecks)
        # * [Global](/compute/docs/reference/rest/v1/healthChecks)
        #
        # These health check resources can be used for load balancing and for
        # autohealing VMs in a managed instance group (MIG).
        #
        # **Load balancing**
        #
        # Health check requirements vary depending on the type of load balancer. For
        # details about the type of health check supported for
        # each load balancer and corresponding backend type,
        # see Health
        # checks overview: Load balancer guide.
        #
        # **Autohealing in MIGs**
        #
        # The health checks that you use for autohealing VMs in a MIG can be either
        # regional or global. For more information, see  Set up an
        # application health check and autohealing.

      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).
      x__xgafv: string, V1 error format.
        Allowed values
          1 - v1 error format
          2 - v2 error format

`list(project, region, filter=None, maxResults=None, orderBy=None, pageToken=None, returnPartialSuccess=None, x__xgafv=None)`

    Retrieves the list of HealthCheck resources available to the specified
    project.

    Args:
      project: string, Project ID for this request. (required)
      region: string, Name of the region scoping this request. (required)
      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 onresource 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 GoogleRE2 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.
      maxResults: integer, 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`)
      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.
      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.
      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.
      x__xgafv: string, V1 error format.
        Allowed values
          1 - v1 error format
          2 - v2 error format

    Returns:
      An object of the form:

      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

      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
