list method
Lists all the HealthCheckService resources that have been configured for the specified project in the given region.
Request parameters:
project
- Project ID for this request.
Value must have pattern
(?:(?:\[-a-z0-9\]{1,63}\.)*(?:\[a-z\](?:\[-a-z0-9\]{0,61}\[a-z0-9\])?):)?(?:\[0-9\]{1,19}|(?:\[a-z0-9\](?:\[-a-z0-9\]{0,61}\[a-z0-9\])?))
.
region
- Name of the region scoping this request.
Value must have pattern \[a-z\](?:\[-a-z0-9\]{0,61}\[a-z0-9\])?
.
filter
- 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.
maxResults
- 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
- 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
- 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
- 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.
$fields
- Selector specifying which fields to include in a partial
response.
Completes with a HealthCheckServicesList.
Completes with a commons.ApiRequestError if the API endpoint returned an error.
If the used http.Client
completes with an error when making a REST call,
this method will complete with the same error.
