Class LoggingClient (3.20.7)

GitHub RepositoryProduct Reference

Service Description: Service for ingesting and querying logs.

This class provides the ability to make remote calls to the backing service through method calls that map to API methods. Sample code to get started:


 // This snippet has been automatically generated and should be regarded as a code template only.
 // It will require modifications to work:
 // - It may require correct/in-range values for request initialization.
 // - It may require specifying regional endpoints when creating the service client as shown in
 // https://cloud.google.com/java/docs/setup#configure_endpoints_for_the_client_library
 try (LoggingClient loggingClient = LoggingClient.create()) {
   LogName logName = LogName.ofProjectLogName("[PROJECT]", "[LOG]");
   loggingClient.deleteLog(logName);
 }

Note: close() needs to be called on the LoggingClient object to clean up resources such as threads. In the example above, try-with-resources is used, which automatically calls close().

Methods
Method Description Method Variants

DeleteLog

Deletes all the log entries in a log for the _Default Log Bucket. The log reappears if it receives new entries. Log entries written shortly before the delete operation might not be deleted. Entries received after the delete operation with a timestamp before the operation will be deleted.

Request object method variants only take one parameter, a request object, which must be constructed before the call.

  • deleteLog(DeleteLogRequest request)

"Flattened" method variants have converted the fields of the request object into function parameters to enable multiple ways to call the same method.

  • deleteLog(LogName logName)

  • deleteLog(String logName)

Callable method variants take no parameters and return an immutable API callable object, which can be used to initiate calls to the service.

  • deleteLogCallable()

WriteLogEntries

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)

Request object method variants only take one parameter, a request object, which must be constructed before the call.

  • writeLogEntries(WriteLogEntriesRequest request)

"Flattened" method variants have converted the fields of the request object into function parameters to enable multiple ways to call the same method.

  • writeLogEntries(LogName logName, MonitoredResource resource, Map<String, String> labels, List<LogEntry> entries)

  • writeLogEntries(String logName, MonitoredResource resource, Map<String, String> labels, List<LogEntry> entries)

Callable method variants take no parameters and return an immutable API callable object, which can be used to initiate calls to the service.

  • writeLogEntriesCallable()

ListLogEntries

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.

Request object method variants only take one parameter, a request object, which must be constructed before the call.

  • listLogEntries(ListLogEntriesRequest request)

"Flattened" method variants have converted the fields of the request object into function parameters to enable multiple ways to call the same method.

  • listLogEntries(List<String> resourceNames, String filter, String orderBy)

ListMonitoredResourceDescriptors

Lists the descriptors for monitored resource types used by Logging.

Request object method variants only take one parameter, a request object, which must be constructed before the call.

  • listMonitoredResourceDescriptors(ListMonitoredResourceDescriptorsRequest request)

Callable method variants take no parameters and return an immutable API callable object, which can be used to initiate calls to the service.

  • listMonitoredResourceDescriptorsPagedCallable()

  • listMonitoredResourceDescriptorsCallable()

ListLogs

Lists the logs in projects, organizations, folders, or billing accounts. Only logs that have entries are listed.

Request object method variants only take one parameter, a request object, which must be constructed before the call.

  • listLogs(ListLogsRequest request)

"Flattened" method variants have converted the fields of the request object into function parameters to enable multiple ways to call the same method.

  • listLogs(BillingAccountName parent)

  • listLogs(FolderName parent)

  • listLogs(OrganizationName parent)

  • listLogs(ProjectName parent)

  • listLogs(String parent)

Callable method variants take no parameters and return an immutable API callable object, which can be used to initiate calls to the service.

  • listLogsPagedCallable()

  • listLogsCallable()

TailLogEntries

Streaming read of log entries as they are ingested. Until the stream is terminated, it will continue reading logs.

Callable method variants take no parameters and return an immutable API callable object, which can be used to initiate calls to the service.

  • tailLogEntriesCallable()

See the individual methods for example code.

Many parameters require resource names to be formatted in a particular way. To assist with these names, this class includes a format method for each type of name, and additionally a parse method to extract the individual identifiers contained within names that are returned.

This class can be customized by passing in a custom instance of LoggingSettings to create(). For example:

To customize credentials:


 // This snippet has been automatically generated and should be regarded as a code template only.
 // It will require modifications to work:
 // - It may require correct/in-range values for request initialization.
 // - It may require specifying regional endpoints when creating the service client as shown in
 // https://cloud.google.com/java/docs/setup#configure_endpoints_for_the_client_library
 LoggingSettings loggingSettings =
     LoggingSettings.newBuilder()
         .setCredentialsProvider(FixedCredentialsProvider.create(myCredentials))
         .build();
 LoggingClient loggingClient = LoggingClient.create(loggingSettings);

To customize the endpoint:


 // This snippet has been automatically generated and should be regarded as a code template only.
 // It will require modifications to work:
 // - It may require correct/in-range values for request initialization.
 // - It may require specifying regional endpoints when creating the service client as shown in
 // https://cloud.google.com/java/docs/setup#configure_endpoints_for_the_client_library
 LoggingSettings loggingSettings = LoggingSettings.newBuilder().setEndpoint(myEndpoint).build();
 LoggingClient loggingClient = LoggingClient.create(loggingSettings);

       loggingClient.listLogEntries(resourceNames, filter, orderBy).iterateAll()) {
     // doThingsWith(element);
   }
 }
Parameters
Name Description
resourceNames List<String>

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]

May alternatively be one or more views:

* projects/[PROJECT_ID]/locations/[LOCATION_ID]/buckets/[BUCKET_ID]/views/[VIEW_ID] * organizations/[ORGANIZATION_ID]/locations/[LOCATION_ID]/buckets/[BUCKET_ID]/views/[VIEW_ID] * billingAccounts/[BILLING_ACCOUNT_ID]/locations/[LOCATION_ID]/buckets/[BUCKET_ID]/views/[VIEW_ID] * folders/[FOLDER_ID]/locations/[LOCATION_ID]/buckets/[BUCKET_ID]/views/[VIEW_ID]

Projects listed in the project_ids field are added to this list. A maximum of 100 resources may be specified in a single request.
filter String

Optional. 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 a filter is 20,000 characters.
orderBy 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 their insert_id values.

writeLogEntries(LogName logName, MonitoredResource resource, Map<String,String> labels, List<LogEntry> entries)

public final WriteLogEntriesResponse writeLogEntries(LogName logName, MonitoredResource resource, Map<String,String> labels, List<LogEntry> entries)

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)

Sample code:


 // This snippet has been automatically generated and should be regarded as a code template only.
 // It will require modifications to work:
 // - It may require correct/in-range values for request initialization.
 // - It may require specifying regional endpoints when creating the service client as shown in

   Map<String, String> labels = new HashMap<>();
   List<LogEntry> entries = new ArrayList<>();
   WriteLogEntriesResponse response =
       loggingClient.writeLogEntries(logName, resource, labels, entries);
 }
Parameters
Name Description
logName LogName

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/123/logs/cloudaudit.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 com.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 Map<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 List<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 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.

To improve throughput and to avoid exceeding the quota limit 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.
Returns
Type Description
WriteLogEntriesResponse
