AWS SDK Version 3 for .NET
API Reference

AWS services or capabilities described in AWS Documentation may vary by region/location. Click Getting Started with Amazon AWS to see specific differences applicable to the China (Beijing) Region.

Creates a log group with the specified name. You can create up to 20,000 log groups per account.

You must use the following guidelines when naming a log group:

When you create a log group, by default the log events in the log group never expire. To set a retention policy so that events expire and are deleted after a specified time, use PutRetentionPolicy.

If you associate a AWS Key Management Service (AWS KMS) customer master key (CMK) with the log group, ingested data is encrypted using the CMK. This association is stored as long as the data encrypted with the CMK is still within Amazon CloudWatch Logs. This enables Amazon CloudWatch Logs to decrypt this data whenever it is requested.

If you attempt to associate a CMK with the log group but the CMK does not exist or the CMK is disabled, you receive an InvalidParameterException error.

CloudWatch Logs supports only symmetric CMKs. Do not associate an asymmetric CMK with your log group. For more information, see Using Symmetric and Asymmetric Keys.

Note:

This is an asynchronous operation using the standard naming convention for .NET 4.5 or higher. For .NET 3.5 the operation is implemented as a pair of methods using the standard naming convention of BeginCreateLogGroup and EndCreateLogGroup.
