How to Edit a Metric Policy in AWS MediaStore

To edit a metric policy in AWS, specifically within the AWS MediaStore service, you can easily do so through the console. Metric policies in MediaStore define how metrics are collected and aggregated for your containers, which is crucial for monitoring the performance and health of your media workflows.

Steps to Modify a Metric Policy in AWS MediaStore

Editing a metric policy in MediaStore is a straightforward process, primarily managed through the AWS Management Console.

1. Access the MediaStore Console: Begin by navigating to the AWS MediaStore console. This is your central hub for managing MediaStore containers and their configurations.

2. Select Your Container: On the Containers page, you will see a list of your existing MediaStore containers. Choose the specific container for which you want to modify the metric policy by clicking on its name.

3. Locate Metric Policy Section: Once inside the container's details page, scroll down to find the Metric policy section. This area displays the current configuration for how metrics are handled for this particular container.

4. Initiate Edit: Within the Metric policy section, select the Edit metric policy option. This will open an interface where you can review and modify the existing policy settings.

5. Make Necessary Changes: In the editing interface, you can adjust various parameters of your metric policy. This might include:

   • Metric aggregation settings: How data points are combined (e.g., sum, average, maximum).
   • Data retention periods: How long metric data is stored.
   • Specific metric dimensions: Which attributes of your media assets or container usage are included in the metrics.

6. Save Your Changes: After making all the desired modifications, choose Save to apply the updated metric policy to your MediaStore container. The changes will typically take effect shortly after saving.

Understanding MediaStore Metric Policies

A metric policy in AWS MediaStore dictates how CloudWatch metrics are generated for your container. These metrics provide valuable insights into your container's performance, such as egress bandwidth, object count, and errors. By editing a metric policy, you can fine-tune the granularity and types of data collected, allowing for more precise monitoring and cost optimization.

Why Edit a Metric Policy?

• Refine Monitoring: Adjust the policy to collect more relevant data for your specific use cases, helping you identify performance bottlenecks or unusual activity.
• Optimize Costs: Control the level of detail for metrics. While more detailed metrics can offer deeper insights, they might also incur higher costs for storage and analysis in CloudWatch.
• Adapt to Workload Changes: As your media workflows evolve, your monitoring needs may change. Updating the metric policy ensures your metrics remain aligned with your operational requirements.

Example Scenario:

Imagine you have a MediaStore container serving live video streams. Initially, you might have a standard metric policy. However, during peak viewership events, you might want to increase the frequency of data collection or add specific dimensions to track egress traffic more closely per region. Editing your metric policy allows you to implement these changes without affecting the underlying media storage or delivery.

Key Considerations

• Impact on CloudWatch: Changes to your MediaStore metric policy directly affect the metrics sent to Amazon CloudWatch. Be mindful of how these changes might influence your existing CloudWatch alarms, dashboards, and monitoring tools.
• Permission Requirements: Ensure your AWS Identity and Access Management (IAM) user or role has the necessary permissions to modify MediaStore container policies. Typically, this involves mediastore:PutMetricPolicy permissions.
• Review Documentation: For advanced configurations or troubleshooting, always refer to the official AWS MediaStore documentation for the most up-to-date and comprehensive information.

By following these steps, you can effectively manage and customize the metric collection for your AWS MediaStore containers, ensuring you have the right data to maintain optimal performance and reliability.
