Amazon CloudWatch agent adds Shared Memory Metrics

Amazon CloudWatch agent now supports collection of shared memory utilization metrics from Linux hosts running on Amazon EC2 or on-premises environments. This new capability enables you to monitor total shared memory usage in CloudWatch, alongside existing memory metrics like free memory, used memory, and cached memory. Enterprise applications such as SAP HANA and Oracle RDBMS make extensive use of shared memory segments that were previously not captured in standard memory metrics. By enabling shared memory metric collection in your CloudWatch agent configuration file, you can now accurately assess total memory utilization across your hosts, helping you optimize host and application configurations and make informed decisions about instance sizing. Amazon CloudWatch agent is supported in all commercial AWS Regions and AWS GovCloud (US) Regions. For Amazon CloudWatch custom metrics pricing, see the [CloudWatch Pricing](https://aws.amazon.com/cloudwatch/pricing/) page. To get started, see [Configuring the CloudWatch agent](https://docs.aws.amazon.com/AmazonCloudWatch/latest/monitoring/CloudWatch-Agent-Configuration-File-Details.html) in the Amazon CloudWatch User Guide.
