@Generated(value="jsii-pacmak/1.120.0 (build 192dc88)", date="2025-12-05T22:26:39.847Z") @Stability(Stable) public class CfnLogStream extends CfnResource implements IInspectable, ILogStreamRef
The AWS::Logs::LogStream resource specifies an Amazon CloudWatch Logs log stream in a specific log group.

A log stream represents the sequence of events coming from an application instance or resource that you are monitoring.

There is no limit on the number of log streams that you can create for a log group.

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

  • Log stream names must be unique within the log group.
  • Log stream names can be between 1 and 512 characters long.
  • The ':' (colon) and '*' (asterisk) characters are not allowed.

Example: 

 // The code below shows an example of how to instantiate this type.
 // The values are placeholders you should change.
 import software.amazon.awscdk.services.logs.*;
 CfnLogStream cfnLogStream = CfnLogStream.Builder.create(this, "MyCfnLogStream")
         .logGroupName("logGroupName")
         // the properties below are optional
         .logStreamName("logStreamName")
         .build();
