Amazon Ec2 Memory Usage

Monitor Memory Utilization of Your EC2 Instance

Historical Performance and Recommendations

By comparing current Amazon EC2 performance to historical data, you can identify normal performance and detect any anomalies. Memory utilization metrics can also help you with recommendations on right-sizing your instance.

Monitoring Memory Utilization with CloudWatch

The recommended method for monitoring memory usage is to create a custom CloudWatch metric using the following steps:

1. Log in to the AWS Management Console and navigate to the CloudWatch service.
2. Click on "Create Metric" and select "Custom Metric."
3. Enter a name for your metric, such as "EC2 Memory Utilization," and select "Percent" as the unit.
4. Select the "Namespace" for your metric, which can be "AWS/EC2" or a custom namespace you create.
5. Configure the metric dimensions, such as the EC2 instance ID.
6. Enter the following expression to calculate the memory utilization: `100 * (used_memory / total_memory)`
7. Click on "Create Metric" to save your new metric.

Once you have created the custom metric, you can monitor memory utilization for your EC2 instance by creating an alarm or graph in CloudWatch.

General Purpose Instances

General purpose instances provide a balance of compute, memory, and networking resources and can be used for a wide range of workloads. They are a good choice for applications that require a combination of resources, such as web servers, application servers, and databases.
