Extending Visibility: Amazon CloudWatch Now Supports Querying Metrics Data Up to Two Weeks Old
Amazon Web Services (AWS) is pleased to announce a significant enhancement to Amazon CloudWatch, its comprehensive monitoring and observability service. Effective September 3, 2025, CloudWatch now empowers users to query their metrics data for a period of up to two weeks. This update significantly expands the historical data retention and analysis capabilities for CloudWatch metrics, offering greater flexibility and deeper insights into application and resource performance.
Previously, the queryable retention period for CloudWatch metrics was more limited. This new capability addresses a common customer request for extended historical data access, enabling more robust trend analysis, anomaly detection over longer periods, and more informed troubleshooting.
Key Benefits of This Enhancement:
- Deeper Historical Analysis: With the ability to query up to two weeks of metrics data, users can now conduct more comprehensive analysis of performance trends, seasonal patterns, and the impact of changes deployed over longer timeframes. This is particularly valuable for understanding the long-term health and behavior of applications and infrastructure.
- Enhanced Troubleshooting: When issues arise, having access to a two-week history of metrics can be invaluable for pinpointing the root cause. It allows for the correlation of events and performance degradation across a more extended period, making it easier to identify the sequence of actions that led to a problem.
- Improved Capacity Planning: Understanding resource utilization and performance over a two-week window provides a more accurate picture for capacity planning. This can help organizations anticipate future needs, optimize resource allocation, and avoid potential bottlenecks.
- More Effective Anomaly Detection: Identifying unusual deviations in metrics often requires observing data over time. The extended retention period allows for the establishment of more reliable baseline behaviors, leading to more accurate and actionable anomaly detection.
- Greater Flexibility for Dashboards and Alarms: Users can now configure CloudWatch dashboards and alarms to reference a longer historical data range, providing more context and a broader perspective on the systems they are monitoring.
This expansion of CloudWatch’s queryable metrics data retention is a testament to AWS’s ongoing commitment to providing customers with the tools they need to effectively manage and optimize their cloud environments. By offering greater visibility into historical performance, this enhancement empowers teams to make more informed decisions, proactively address potential issues, and ensure the reliability and efficiency of their applications and services running on AWS.
We encourage all CloudWatch users to take advantage of this new capability to enhance their monitoring strategies and gain deeper insights into their operations.
