Constructor.

Parameters
NameDescription
channel grpc.Channel

DEPRECATED. A Channel instance through which to make calls. This argument is mutually exclusive with credentials; providing both will raise an exception.

credentials google.auth.credentials.Credentials

The authorization credentials to attach to requests. These credentials identify this application to the service. If none are specified, the client will attempt to ascertain the credentials from the environment. This argument is mutually exclusive with providing a transport instance to transport; doing so will raise an exception.

client_config dict

DEPRECATED. A dictionary of call options for each method. If not specified, the default configuration is used.

client_info google.api_core.gapic_v1.client_info.ClientInfo

The client info used to send a user-agent string along with API requests. If None, then default info will be used. Generally, you only need to set this if you're developing your own client library.

client_options Union[dict, google.api_core.client_options.ClientOptions]

Client options used to set user options on the client. API Endpoint should be set through client_options.

billing_log_path

billing_log_path(billing_account, log)

list_log_entries(resource_names, project_ids=None, filter_=None, order_by=None, page_size=None, retry=<_MethodDefault._DEFAULT_VALUE: <object object>>, timeout=<_MethodDefault._DEFAULT_VALUE: <object object>>, metadata=None)

Lists log entries. Use this method to retrieve log entries that originated from a project/folder/organization/billing account. For ways to export log entries, see Exporting Logs <https://cloud.google.com/logging/docs/export>__.

.. rubric:: Example

from google.cloud import logging_v2

client = logging_v2.LoggingServiceV2Client()

TODO: Initialize resource_names:

resource_names = []

Iterate over all results

for element in client.list_log_entries(resource_names): ... # process element ... pass

Alternatively:

Iterate over results one page at a time

for page in client.list_log_entries(resource_names).pages: ... for element in page: ... # process element ... pass

Parameters
NameDescription
resource_names list[str]

Required. Names of one or more parent resources from which to retrieve log entries: :: "projects/[PROJECT_ID]" "organizations/[ORGANIZATION_ID]" "billingAccounts/[BILLING_ACCOUNT_ID]" "folders/[FOLDER_ID]" Projects listed in the project_ids field are added to this list.

project_ids list[str]

Deprecated. Use resource_names instead. One or more project identifiers or project numbers from which to retrieve log entries. Example: "my-project-1A".

filter_ str

Optional. A filter that chooses which log entries to return. See Advanced Logs Queries https://cloud.google.com/logging/docs/view/advanced-queries__. 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 that is not listed in resource_names will cause the filter to return no results. The maximum length of the filter is 20000 characters.

order_by str

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 their insert_id values.

page_size int

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.

Writes log entries to Logging. This API method is the only way to send log entries to Logging. This method is used, directly or indirectly, by the Logging agent (fluentd) and all logging libraries configured to use Logging. A single request may contain log entries for a maximum of 1000 different resources (projects, organizations, billing accounts or folders)

.. rubric:: Example

from google.cloud import logging_v2

client = logging_v2.LoggingServiceV2Client()

TODO: Initialize entries:

entries = []

response = client.write_log_entries(entries)

Parameters
NameDescription
entries list[Union[dict, LogEntry]]

Required. The log entries to send to Logging. The order of log entries in this list does not matter. Values supplied in this method's log_name, resource, and labels fields are copied into those log entries in this list that do not include values for their corresponding fields. For more information, see the LogEntry type. If the timestamp or insert_id fields are missing in log entries, then this method supplies the current time or a unique identifier, respectively. The supplied values are chosen so that, among the log entries that did not supply their own values, the entries earlier in the list will sort before the entries later in the list. See the entries.list method. Log entries with timestamps that are more than the logs retention period https://cloud.google.com/logging/quota-policy in the past or more than 24 hours in the future will not be available when calling entries.list. However, those log entries can still be exported with LogSinks https://cloud.google.com/logging/docs/api/tasks/exporting-logs. To improve throughput and to avoid exceeding the quota limit https://cloud.google.com/logging/quota-policy__ for calls to entries.write, you should try to include several log entries in this list, rather than calling this method for each individual log entry. If a dict is provided, it must be of the same form as the protobuf message LogEntry

log_name str

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" "organizations/1234567890/logs/cloudresourcemanager.googleapis.com%2Factivity" The permission logging.logEntries.create is needed on each project, organization, billing account, or folder that is receiving new log entries, whether the resource is specified in logName or in an individual log entry.

resource Union[dict, 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. If a dict is provided, it must be of the same form as the protobuf message MonitoredResource

labels dict[str -> str]

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 bool

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.

dry_run bool

Optional. If true, the request should expect normal response, but the entries won't be persisted nor exported. Useful for checking whether the logging API endpoints are working properly before sending valuable data.

retry Optional[google.api_core.retry.Retry]

A retry object used to retry requests. If None is specified, requests will be retried using a default configuration.

timeout Optional[float]

The amount of time, in seconds, to wait for the request to complete. Note that if retry is specified, the timeout applies to each individual attempt.

metadata Optional[Sequence[Tuple[str, str]]]

Additional metadata that is provided to the method.

Exceptions
TypeDescription
google.api_core.exceptions.GoogleAPICallErrorIf the request failed for any reason.
google.api_core.exceptions.RetryErrorIf the request failed due to a retryable error and retry attempts failed.
ValueErrorIf the parameters are invalid.
