  #
  # @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
  #   inserted into those log entries in this list that do not provide their own
  #   values.
  #
  #   Stackdriver Logging also creates and inserts values for +timestamp+ and
  #   +insert_id+ if the entries do not provide them. The created +insert_id+ for
  #   the N'th entry in this list will be greater than earlier entries and less
  #   than later entries.  Otherwise, the order of log entries in this list does
  #   not matter.
  #
  #   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 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]"
  #       "billingAccounts/[BILLING_ACCOUNT_ID]/logs/[LOG_ID]"
  #       "folders/[FOLDER_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.
  # @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 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, then the response status is the error associated
  #   with one of the failed entries and the response includes error details
  #   keyed by the entries' zero-based index in the +entries.write+ method.
  # @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 filter [String]
  #   Optional. A filter that chooses which log entries to return.  See {Advanced
  #   Logs Filters}[https://cloud.google.com/logging/docs/view/advanced_filters].  Only log entries that
  #   match the filter are returned.  An empty filter matches all log entries in
  #   the resources listed in +resource_names+. Referencing a parent resource

  #   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

  • 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 inserted into those log entries in this list that do not provide their own values.

    Stackdriver Logging also creates and inserts values for +timestamp+ and +insert_id+ if the entries do not provide them. The created +insert_id+ for the N'th entry in this list will be greater than earlier entries and less than later entries. Otherwise, the order of log entries in this list does not matter.

    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.

  • 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]"
"billingAccounts/[BILLING_ACCOUNT_ID]/logs/[LOG_ID]"
"folders/[FOLDER_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.

  • 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, then the response status is the error associated with one of the failed entries and the response includes error details keyed by the entries' zero-based index in the +entries.write+ method.

  • 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.
