Cloud Logging Client

Client for interacting with the Google Cloud Logging API.

class google.cloud.logging_v2.client.Client(*, project=None, credentials=None, _http=None, _use_grpc=None, client_info=None, client_options=None)

Bases: google.cloud.client.ClientWithProject

Client to bundle configuration needed for API requests.

Parameters
- project (Optional[str]) – the project which the client acts on behalf of. If not passed, falls back to the default inferred from the environment.
- credentials (Optional[google.auth.credentials.Credentials]) – Thehe OAuth2 Credentials to use for this client. If not passed (and if no _http object is passed), falls back to the default inferred from the environment.
- _http (Optional[requests.Session]) – HTTP object to make requests. Can be any object that defines request() with the same interface as requests.Session.request(). If not passed, an _http object is created that is bound to the credentials for the current object. This parameter should be considered private, and could change in the future.
- _use_grpc (Optional[bool]) – Explicitly specifies whether to use the gRPC transport or HTTP. If unset, falls back to the GOOGLE_CLOUD_DISABLE_GRPC environment variable This parameter should be considered private, and could change in the future.
- client_info (Optional[Union[google.api_core.client_info.ClientInfo, *[google.api_core.gapic_v1.client_info.ClientInfo](https://googleapis.dev/python/google-api-core/latest/client_info.html#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 library or partner tool.
- client_options (Optional[Union[dict, *[google.api_core.client_options.ClientOptions](https://googleapis.dev/python/google-api-core/latest/client_options.html#google.api_core.client_options.ClientOptions)]*]) – Client options used to set user options on the client. API Endpoint should be set through client_options.

The scopes required for authenticating as a Logging consumer.

get_default_handler(**kw)

Return the default logging handler based on the local environment.

Parameters

kw (dict) – keyword args passed to handler constructor
Returns

The default log handler based on the environment
Return type

logging.Handler

list_entries(*, resource_names=None, filter_=None, order_by=None, max_results=None, page_size=None, page_token=None)

Return a generator of log entry resources.

Parameters
- resource_names (Sequence[str]) – 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]"
```
  If not passed, defaults to the project bound to the API’s client.
- filter (str) – a filter expression. See https://cloud.google.com/logging/docs/view/advanced_filters
- order_by (str) – or DESCENDING.
- max_results (Optional[int]) – Optional. The maximum number of entries to return. Non-positive values are treated as 0. If None, uses API defaults.
- page_size (int) – number of entries to fetch in each API call. Although requests are paged internally, logs are returned by the generator one at a time. If not passed, defaults to a value set by the API.
- page_token (str) – opaque marker for the starting “page” of entries. If not passed, the API will return the first page of entries.
Returns

Generator[~logging_v2.LogEntry]

list_metrics(*, max_results=None, page_size=None, page_token=None)

Parameters
- max_results (Optional[int]) – Optional. The maximum number of entries to return. Non-positive values are treated as 0. If None, uses API defaults.

- page_token (str) – opaque marker for the starting “page” of entries. If not passed, the API will return the first page of entries.
Returns

Generator[logging_v2.Metric]

list_sinks(*, parent=None, max_results=None, page_size=None, page_token=None)

List sinks for the a parent resource.

See https://cloud.google.com/logging/docs/reference/v2/rest/v2/projects.sinks/list

"folders/[FOLDER_ID]".
```
  If not passed, defaults to the project bound to the API’s client.
- max_results (Optional[int]) – Optional. The maximum number of entries to return. Non-positive values are treated as 0. If None, uses API defaults.

logger(name, *, labels=None, resource=None)

Creates a logger bound to the current client.

Parameters
- name (str) – The name of the logger to be constructed.
- resource (Optional[Resource]) – a monitored resource object representing the resource the code was run on. If not given, will be inferred from the environment.

setup_logging(*, log_level=20, excluded_loggers=('google.cloud', 'google.auth', 'google_auth_httplib2', 'google.api_core.bidi', 'werkzeug'), **kw)

Attach default Cloud Logging handler to the root logger.

This method uses the default log handler, obtained by get_default_handler(), and attaches it to the root Python logger, so that a call such as logging.warn, as well as all child loggers, will report to Cloud Logging.

Parameters
- log_level (Optional[int]) – Python logging log level. Defaults to logging.INFO.
- excluded_loggers (Optional[Tuple[str]]) – The loggers to not attach the handler to. This will always include the loggers in the path of the logging client itself.
Returns

keyword args passed to handler constructor
Return type

dict

sink(name, *, filter_=None, destination=None)

Creates a sink bound to the current client.

Parameters
- name (str) – the name of the sink to be constructed.
- filter (Optional[str]) – the advanced logs filter expression defining the entries exported by the sink. If not passed, the instance should already exist, to be refreshed via Sink.reload().
- destination (str) – destination URI for the entries exported by the sink. If not passed, the instance should already exist, to be refreshed via Sink.reload().
Returns

Sink created with the current client.
Return type

Sink

property sinks_api()
