#initialize(service_path: SERVICE_ADDRESS, port: DEFAULT_SERVICE_PORT, channel: nil, chan_creds: nil, scopes: ALL_SCOPES, client_config: {}, timeout: DEFAULT_TIMEOUT, app_name: nil, app_version: nil, lib_name: nil, lib_version: "") ⇒ LoggingServiceV2Client

Returns a new instance of LoggingServiceV2Client

Parameters:

  • service_path (String) —

    The domain name of the API remote host.

  • port (Integer) —

    The port on which to connect to the remote host.

  • channel (Channel) —

    A Channel object through which to make calls.

  • chan_creds (Grpc::ChannelCredentials) —

    A ChannelCredentials for the setting up the RPC client.

  • 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.

  #   For more information about log names, see
  #   LogEntry.
  # @param resource [Google::Api::MonitoredResource]
  #   Optional. A default monitored resource object that is assigned to all log
  #   entries in +entries+ that do not specify a value for +resource+. Example:
  #
  #       { "type": "gce_instance",
  #         "labels": {
  #           "zone": "us-central1-a", "instance_id": "00000000000000000000" }}
  #
  #   See LogEntry.
  # @param labels [Hash{String => String}]
  #   Optional. Default labels that are added to the +labels+ field of all log
  #   entries in +entries+. If a log entry already has a label with the same key
  #   as a label in this parameter, then the log entry's label is not changed.
  #   See LogEntry.
  # @param entries [Array<Google::Logging::V2::LogEntry>]
  #   Required. The log entries to write. Values supplied for the fields
  #   +log_name+, +resource+, and +labels+ in this +entries.write+ request are
  #   added to those log entries that do not provide their own values for the
  #   fields.
  #
  #   To improve throughput and to avoid exceeding the
  #   {quota limit}[https://cloud.google.com/logging/quota-policy] for calls to +entries.write+,
  #   you should write multiple log entries at once rather than
  #   calling this method for each individual log entry.
  # @param partial_success [true, false]
  #   Optional. Whether valid entries should be written even if some other
  #   entries fail due to INVALID_ARGUMENT or PERMISSION_DENIED errors. If any
  #   entry is not written, the response status will be the error associated
  #   with one of the failed entries and include error details in the form of
  #   WriteLogEntriesPartialErrors.
  # @param options [Google::Gax::CallOptions]
  #   Overrides the default settings for this call, e.g, timeout,
  #   retries, etc.
  # @return [Google::Logging::V2::WriteLogEntriesResponse]
  # @raise [Google::Gax::GaxError] if the RPC is aborted.
  # @example

  #
  # @param project_ids [Array<String>]
  #   Deprecated. Use +resource_names+ instead.  One or more project identifiers
  #   or project numbers from which to retrieve log entries.  Example:
  #   +"my-project-1A"+. If present, these project identifiers are converted to

  #   match the filter are returned.  An empty filter matches all log entries in
  #   the resources listed in +resource_names+. Referencing a parent resource
  #   that is not listed in +resource_names+ will cause the filter to return no
  #   results.
  #   The maximum length of the filter is 20000 characters.
  # @param order_by [String]
  #   Optional. How the results should be sorted.  Presently, the only permitted
  #   values are +"timestamp asc"+ (default) and +"timestamp desc"+. The first
  #   option returns entries in order of increasing values of
  #   +LogEntry.timestamp+ (oldest first), and the second option returns entries
  #   in order of decreasing timestamps (newest first).  Entries with equal
  #   timestamps are returned in order of +LogEntry.insertId+.
  # @param page_size [Integer]
  #   The maximum number of resources contained in the underlying API

#write_log_entries(entries, log_name: nil, resource: nil, labels: nil, partial_success: nil, options: nil) ⇒ Google::Logging::V2::WriteLogEntriesResponse

Writes log entries to Stackdriver Logging. All log entries are written by this method.

Examples:

entries = []
response = logging_service_v2_client.write_log_entries(entries)

Parameters:

  • log_name (String) —

    Optional. A default log resource name that is assigned to all log entries in +entries+ that do not specify a value for +log_name+:

    "projects/[PROJECT_ID]/logs/[LOG_ID]"
"organizations/[ORGANIZATION_ID]/logs/[LOG_ID]"

    +[LOG_ID]+ must be URL-encoded. For example, +"projects/my-project-id/logs/syslog"+ or +"organizations/1234567890/logs/cloudresourcemanager.googleapis.com%2Factivity"+. For more information about log names, see LogEntry.

  • resource (Google::Api::MonitoredResource) —

    Optional. A default monitored resource object that is assigned to all log entries in +entries+ that do not specify a value for +resource+. Example:

    { "type": "gce_instance",
  "labels": {
    "zone": "us-central1-a", "instance_id": "00000000000000000000" }}

    See LogEntry.

  • labels (Hash{String => String}) —

    Optional. Default labels that are added to the +labels+ field of all log entries in +entries+. If a log entry already has a label with the same key as a label in this parameter, then the log entry's label is not changed. See LogEntry.

  • entries (Array<Google::Logging::V2::LogEntry>) —

    Required. The log entries to write. Values supplied for the fields +log_name+, +resource+, and +labels+ in this +entries.write+ request are added to those log entries that do not provide their own values for the fields.

    To improve throughput and to avoid exceeding the limit[https://cloud.google.com/logging/quota-policy] for calls to +entries.write+, you should write multiple log entries at once rather than calling this method for each individual log entry.

  • partial_success (true, false) —

    Optional. Whether valid entries should be written even if some other entries fail due to INVALID_ARGUMENT or PERMISSION_DENIED errors. If any entry is not written, the response status will be the error associated with one of the failed entries and include error details in the form of WriteLogEntriesPartialErrors.

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

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

Returns:

Raises:

  • (Google::Gax::GaxError) —

    if the RPC is aborted.
