Overview

The AlertPolicyService API is used to manage (list, create, delete, edit) alert policies in Stackdriver Monitoring. An alerting policy is a description of the conditions under which some aspect of your system is considered to be "unhealthy" and the ways to notify people or services about this state. In addition to using this API, alert policies can also be managed through Stackdriver Monitoring, which can be reached by clicking the "Monitoring" tab in Cloud Console.

Constructor Details

#initialize(credentials: nil, scopes: ALL_SCOPES, client_config: {}, timeout: DEFAULT_TIMEOUT, metadata: nil, exception_transformer: nil, lib_name: nil, lib_version: "") ⇒ AlertPolicyServiceClient

Returns a new instance of AlertPolicyServiceClient

Parameters:

  • credentials (Google::Auth::Credentials, String, Hash, GRPC::Core::Channel, GRPC::Core::ChannelCredentials, Proc) —

    Provides the means for authenticating requests made by the client. This parameter can be many types. A Google::Auth::Credentials uses a the properties of its represented keyfile for authenticating requests made by this client. A String will be treated as the path to the keyfile to be used for the construction of credentials for this client. A Hash will be treated as the contents of a keyfile to be used for the construction of credentials for this client. A GRPC::Core::Channel will be used to make calls through. A GRPC::Core::ChannelCredentials for the setting up the RPC client. The channel credentials should already be composed with a GRPC::Core::CallCredentials object. A Proc will be used as an updater_proc for the Grpc channel. The proc transforms the metadata for requests, generally, to give OAuth credentials.

  • scopes (Array<String>) —

    The OAuth scopes for this service. This parameter is ignored if an updater_proc is supplied.

  • client_config (Hash) —

    A Hash for call options for each method. See Google::Gax#construct_settings for the structure of this data. Falls back to the default config if not specified or the specified config is missing data points.

  • timeout (Numeric) —

    The default timeout, in seconds, for calls made through this client.

  • metadata (Hash) —

    Default metadata to be sent with each request. This can be overridden on a per call basis.

  • exception_transformer (Proc) —

    An optional proc that intercepts any exceptions raised during an API call to inject custom error handling.

Instance Method Details

#create_alert_policy(name, alert_policy, options: nil) {|result, operation| ... } ⇒ Google::Monitoring::V3::AlertPolicy

Creates a new alerting policy.

Examples:

require "google/cloud/monitoring"

alert_policy_service_client = Google::Cloud::Monitoring::AlertPolicy.new(version: :v3)
formatted_name = Google::Cloud::Monitoring::V3::AlertPolicyServiceClient.project_path("[PROJECT]")

# TODO: Initialize +alert_policy+:
alert_policy = {}
response = alert_policy_service_client.create_alert_policy(formatted_name, alert_policy)

Parameters:

  • name (String) —

    The project in which to create the alerting policy. The format is +projects/[PROJECT_ID]+.

    Note that this field names the parent container in which the alerting policy will be written, not the name of the created policy. The alerting policy that is returned will have a name that contains a normalized representation of this name as a prefix but adds a suffix of the form +/alertPolicies/[POLICY_ID]+, identifying the policy in the container.

  • alert_policy (Google::Monitoring::V3::AlertPolicy | Hash) —

    The requested alerting policy. You should omit the +name+ field in this policy. The name will be returned in the new policy, including a new [ALERT_POLICY_ID] value. A hash of the same form as Google::Monitoring::V3::AlertPolicy can also be provided.

  • options (Google::Gax::CallOptions) —

    Overrides the default settings for this call, e.g, timeout, retries, etc.

Yields:

  • (result, operation) —

    Access the result along with the RPC operation

Yield Parameters:

Returns:

Raises:

  • (Google::Gax::GaxError) —

    if the RPC is aborted.

end

#list_alert_policies(name, filter: nil, order_by: nil, page_size: nil, options: nil) {|result, operation| ... } ⇒ Google::Gax::PagedEnumerable<Google::Monitoring::V3::AlertPolicy>

Lists the existing alerting policies for the project.

Examples:

require "google/cloud/monitoring"

alert_policy_service_client = Google::Cloud::Monitoring::AlertPolicy.new(version: :v3)
formatted_name = Google::Cloud::Monitoring::V3::AlertPolicyServiceClient.project_path("[PROJECT]")

# Iterate over all results.
alert_policy_service_client.list_alert_policies(formatted_name).each do |element|
  # Process element.
end

# Or iterate over results one page at a time.
alert_policy_service_client.list_alert_policies(formatted_name).each_page do |page|
  # Process each page at a time.
  page.each do |element|
    # Process element.
  end
end

Parameters:

  • name (String) —

    The project whose alert policies are to be listed. The format is

    projects/[PROJECT_ID]

    Note that this field names the parent container in which the alerting policies to be listed are stored. To retrieve a single alerting policy by name, use the GetAlertPolicy operation, instead.

  • filter (String) —

    If provided, this field specifies the criteria that must be met by alert policies to be included in the response.

    For more details, see sorting and filtering.

  • order_by (String) —

    A comma-separated list of fields by which to sort the result. Supports the same set of field references as the +filter+ field. Entries can be prefixed with a minus sign to sort by the field in descending order.

    For more details, see sorting and filtering.

  • page_size (Integer) —

    The maximum number of resources contained in the underlying API response. If page streaming is performed per-resource, this parameter does not affect the return value. If page streaming is performed per-page, this determines the maximum number of resources in a page.

  • options (Google::Gax::CallOptions) —

    Overrides the default settings for this call, e.g, timeout, retries, etc.

Yields:

  • (result, operation) —

    Access the result along with the RPC operation

Yield Parameters:

Returns:

  • (Google::Gax::PagedEnumerable<Google::Monitoring::V3::AlertPolicy>) —

    An enumerable of Google::Monitoring::V3::AlertPolicy instances. See Google::Gax::PagedEnumerable documentation for other operations such as per-page iteration or access to the response object.

Raises:

  • (Google::Gax::GaxError) —

    if the RPC is aborted.

end

#update_alert_policy(alert_policy, update_mask: nil, options: nil) {|result, operation| ... } ⇒ Google::Monitoring::V3::AlertPolicy

Updates an alerting policy. You can either replace the entire policy with a new one or replace only certain fields in the current alerting policy by specifying the fields to be updated via +updateMask+. Returns the updated alerting policy.

Examples:

require "google/cloud/monitoring"

alert_policy_service_client = Google::Cloud::Monitoring::AlertPolicy.new(version: :v3)

# TODO: Initialize +alert_policy+:
alert_policy = {}
response = alert_policy_service_client.update_alert_policy(alert_policy)

Parameters:

  • alert_policy (Google::Monitoring::V3::AlertPolicy | Hash) —

    Required. The updated alerting policy or the updated values for the fields listed in +update_mask+. If +update_mask+ is not empty, any fields in this policy that are not in +update_mask+ are ignored. A hash of the same form as Google::Monitoring::V3::AlertPolicy can also be provided.

  • update_mask (Google::Protobuf::FieldMask | Hash) —

    Optional. A list of alerting policy field names. If this field is not empty, each listed field in the existing alerting policy is set to the value of the corresponding field in the supplied policy (+alert_policy+), or to the field's default value if the field is not in the supplied alerting policy. Fields not listed retain their previous value.

    Examples of valid field masks include +display_name+, +documentation+, +documentation.content+, +documentation.mime_type+, +user_labels+, +user_label.nameofkey+, +enabled+, +conditions+, +combiner+, etc.

    If this field is empty, then the supplied alerting policy replaces the existing policy. It is the same as deleting the existing policy and adding the supplied policy, except for the following:

    • The new policy will have the same +[ALERT_POLICY_ID]+ as the former policy. This gives you continuity with the former policy in your notifications and incidents.
    • Conditions in the new policy will keep their former +[CONDITION_ID]+ if the supplied condition includes the +name+ field with that +[CONDITION_ID]+. If the supplied condition omits the +name+ field, then a new +[CONDITION_ID]+ is created. A hash of the same form as Google::Protobuf::FieldMask can also be provided.
  • options (Google::Gax::CallOptions) —

    Overrides the default settings for this call, e.g, timeout, retries, etc.

Yields:

  • (result, operation) —

    Access the result along with the RPC operation

Yield Parameters:

Returns:

Raises:

  • (Google::Gax::GaxError) —

    if the RPC is aborted.
