Logstash Output Plugin for AWS CloudWatch Logs

This plugin for Logstash allows you to send events to AWS CloudWatch Logs.

The plugin is published on RubyGems. You can install it directly using the logstash-plugin command:

logstash-plugin install logstash-output-awslogs

Ensure that you have Logstash installed and properly configured before proceeding.

After installing the plugin, add it to your Logstash configuration file:

output {
  awslogs {
    access_key_id => "YOUR_ACCESS_KEY_ID"
    secret_access_key => "YOUR_SECRET_ACCESS_KEY"
    region => "us-east-1"
    log_group_name => "your_log_group_name"
    log_stream_name => "your_log_stream_name"
  }
}

1. Using AWS Session Token: If your environment requires temporary credentials with a session token, you can include it as follows:

   output {
     awslogs {
       access_key_id => "YOUR_ACCESS_KEY_ID"
       secret_access_key => "YOUR_SECRET_ACCESS_KEY"
       session_token => "YOUR_SESSION_TOKEN"
       region => "us-east-1"
       log_group_name => "your_log_group_name"
       log_stream_name => "your_log_stream_name"
     }
   }
   

2. Using IRSA (IAM Roles for Service Accounts): If you are running Logstash in an environment like Amazon EKS or EC2, where IAM roles are available, you can omit access_key_id, secret_access_key, and session_token. The plugin will automatically use the IAM role assigned to the service account or instance.

   output {
     awslogs {
       region => "us-east-1"
       log_group_name => "your_log_group_name"
       log_stream_name => "your_log_stream_name"
     }
   }
   

   Ensure that the IAM role has the necessary permissions to write to CloudWatch Logs.

• access_key_id: Your AWS Access Key ID.
• secret_access_key: Your AWS Secret Access Key.
• session_token: (Optional) Your AWS session token for temporary credentials.
• region: AWS Region (e.g., us-east-1).
• log_group_name: The name of the CloudWatch Logs group.
• log_stream_name: The name of the CloudWatch Logs stream.

Make sure the provided AWS credentials or IAM roles have sufficient permissions to write to CloudWatch Logs.
