Constructor Details

#initialize(credentials: nil, scopes: ALL_SCOPES, client_config: {}, timeout: DEFAULT_TIMEOUT, metadata: nil, exception_transformer: nil, lib_name: nil, lib_version: "") ⇒ MetricsServiceV2Client

Returns a new instance of MetricsServiceV2Client

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.

#list_log_metrics(parent, page_size: nil, options: nil) {|result, operation| ... } ⇒ Google::Gax::PagedEnumerable<Google::Logging::V2::LogMetric>

Lists logs-based metrics.

Examples:

require "google/cloud/logging/v2"

metrics_service_v2_client = Google::Cloud::Logging::V2::MetricsServiceV2Client.new
formatted_parent = Google::Cloud::Logging::V2::MetricsServiceV2Client.project_path("[PROJECT]")

# Iterate over all results.
metrics_service_v2_client.list_log_metrics(formatted_parent).each do |element|
  # Process element.
end

# Or iterate over results one page at a time.
metrics_service_v2_client.list_log_metrics(formatted_parent).each_page do |page|
  # Process each page at a time.
  page.each do |element|
    # Process element.
  end
end

Parameters:

  • parent (String) —

    Required. The name of the project containing the metrics:

    "projects/[PROJECT_ID]"
  • 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::Logging::V2::LogMetric>) —

    An enumerable of Google::Logging::V2::LogMetric 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.

#update_log_metric(metric_name, metric, options: nil) {|result, operation| ... } ⇒ Google::Logging::V2::LogMetric

Creates or updates a logs-based metric.
