Compute Optimizer 會分析 EC2 執行個體的下列 CloudWatch 指標,包括屬於 EC2 Auto Scaling 群組的執行個體。 指標描述 CPUUtilization 執行個體上使用的已配置 EC2 運算單位百分比。此指標可識別在執行個體上執行應用程式所需的處理能力。 MemoryUtilization
For example, the CPU utilization of an Auto Scaling group works (that is, the Amazon EC2 metric CPUUtilization with the metric dimension AutoScalingGroupName) if the load on the Auto Scaling group is distributed across the instances. The memory utilization metric is not one of the ...
步骤4:创建完仪表盘后,在左侧的导航栏中,选择“Metrics”(指标)。 步骤5:在“Metrics”页面中,在左侧的面板中,找到“EC2”(云服务器)部分。 步骤6:在“EC2”部分,选择要监控的指标,如CPU利用率(“CPUUtilization”)和内存使用(“MemoryUsed”)。 步骤7:选择指标后,会显示一个详细的图表,您可以在图表上选择...
memory utilization on the instances for operational visibility. These applications benefit from scaling with memory utilization. You also need memory utilization metrics to get recommendations on right-sizing your EC2 instances. This blog post provides guidance on how to automate setting up memory ...
Describes a utilization metric of a resource, such as an Amazon EC2 instance. Compare the utilization metric data of your resource against its projected utilization metric data to determine the performance difference between your current resource and the recommended option.

A: AWS 不会关闭用户 EC2 实例,哪怕是底层硬件故障。请检查是否有 Autoscaling / Cloudformation 等其他服务触发了操作。打开 Cloudtrail 可以看到 API 调用记录。 Q: EC2 是否支持广播? A: EC2 不支持广播和组播,只支持单播。一些应用中,例如 LVS keepalived,需要特别设置为单播模式。
Amazon EC2 Instance Connect is a simple and secure way to connect to your instances using Secure Shell (SSH). With EC2 Instance Connect, you can control SSH access to your instances using AWS Identity and Access Management (IAM) policies as well as audit connection requests with AWS CloudTrail...
