Amazon CloudWatch Logs has recently introduced account-level retention policies, streamlining the way organizations manage log data across their AWS accounts. This comprehensive guide will explore these new policies in detail, providing you with the knowledge to leverage them efficiently to meet your organization’s retention requirements.
Introduction to Amazon CloudWatch Logs¶
Amazon CloudWatch is a powerful monitoring and observability service that allows you to collect and track metrics, collect log files, and set alarms in your AWS infrastructure. With the introduction of account-level retention policies, managing log data has become significantly more efficient, especially for organizations with multiple log groups.
What Are Account-Level Retention Policies?¶
Account-level retention policies enable you to set uniform log retention standards across all or a subset of your log groups. This is particularly beneficial for compliance and auditing initiatives, allowing teams to ensure that logs are kept for the required duration without the hassle of tracking each log group individually.
- Unified Management: Implement a single retention standard across multiple log groups.
- Customizable Scope: Apply rules to all log groups or target specific prefixes, like
/aws/lambda. - Simplicity: Avoid managing individual policies for each log group.
In the following sections, we will delve into how to create these policies, manage them efficiently, and explore the long-term benefits they offer.
Benefits of Account-Level Retention Policies¶
Implementing account-level retention policies provides numerous benefits that enhance data governance and operational efficiency:
- Centralized Control: Establishing a single retention policy reduces administrative overhead, allowing security teams to focus on compliance and audits without getting bogged down in logistical details.
- Flexibility: Depending on your regulatory requirements, you can set varying retention periods based on log group prefixes.
- Cost-Effectiveness: Since managing these policies incurs no additional costs, organizations can maximize their AWS investment.
Key Features¶
- Policy Length: You can create policies that dictate how long logs are kept, with the longest retention period applying when multiple policies match a single log group.
- Availability: These policies are available in all commercial AWS regions, with exceptions noted.
- Creation and Management: Utilize the AWS Management Console, AWS CLI, or AWS SDKs to manage your policies.

How to Create Account-Level Retention Policies¶
Creating account-level retention policies in Amazon CloudWatch Logs is a straightforward process that can be accomplished through various interfaces. We will outline the steps involved in creating and applying these policies using the AWS Management Console, AWS CLI, and AWS SDKs.
Step 1: Using the AWS Management Console¶
- Log in to AWS Management Console: Start by signing into your AWS account.
- Navigate to CloudWatch: In the services menu, search for and select CloudWatch.
- Select Log Groups: Click on “Logs” in the navigation pane.
- Create Policy:
- Click on “Retention Policies.”
- Choose “Create Policy.”
- Configure your policy by specifying the retention period you need.
Apply your policy to either all log groups or those matching a specific prefix.
Review and Confirm: Review the settings and confirm the creation of your policy.
Step 2: Using the AWS CLI¶
You can also manage your retention policies using the AWS CLI. Here’s an example command to create a policy:
bash
aws logs put-retention-policy –log-group-name
Step 3: Using AWS SDKs¶
If you’re building applications or automations, consider using the AWS SDKs. Here’s a sample code snippet in Python using Boto3:
python
import boto3
client = boto3.client(‘logs’)
Create a retention policy¶
client.put_retention_policy(
logGroupName=’/aws/lambda/my-function’,
retentionInDays=90
)
Managing Retention Policies¶
Once your retention policies are established, efficient management is vital. This includes monitoring their application and making necessary adjustments.
Steps to Monitor and Adjust Policies¶
- Regular Review: Regularly check your policy settings to ensure they meet compliance standards.
- Audit Logs: Use CloudTrail to monitor changes to your CloudWatch logs and retention policies.
- Modify Policies: Update or modify policies as needed based on changing retention requirements.
Common Scenarios for Policy Application¶
- Audit Requirements: Organizations in highly regulated industries may apply longer retention policies for specific log groups.
- Cost Management: By aligning retention policies with business needs, organizations can save on storage costs while maintaining compliance.
Best Practices for Using Account-Level Retention Policies¶
To make the most of your account-level retention policies, consider these best practices:
- Establish Clear Standards: Define a clear set of standards for your retention policies based on regulatory and operational needs.
- Automate Notifications: Set up notifications for when logs are about to expire, ensuring that no critical logs are lost.
- Utilize Compliance Tools: Implement AWS tools like Config and CloudTrail for compliance monitoring and reporting.
