Validate that the CloudWatch agents are sending their monitoring data to CloudWatch.Configure CloudWatch agents to use agent configuration stored in Parameter Store using the Run Command.This configuration is then stored in AWS System Manager Parameter Store These items could be performance counters and logs on the server.

Run the CloudWatch agent configuration wizard, which captures what you want to monitor.

AWS provides a service called AWS Systems Manager Run Command, which enables you to do this agent installation across all your servers.

Install the CloudWatch agent onto your servers.

There are four steps to implement internal monitoring: Also, dashboards can be created to view the health of your Windows servers. The agent then sends this information to Amazon CloudWatch, where rules can be created to alert on certain conditions (for example, low free disk space) and automated responses can be set up (for example, perform backup to clear transaction logs). The agent can also capture logs from the server. For more details, please see Metrics Collected by the CloudWatch Agent.

For Linux, the CloudWatch agent can capture system-level metrics. For Windows, the CloudWatch agent can capture any of the Windows performance monitor counters. To capture the server’s internal performance metrics, a CloudWatch agent must be installed on the instance. AWS places an extra safeguard on gathering data inside a customer’s instance so this capability is not enabled by default. However, to understand what percentage of the disk is being used or what percentage of the memory is being used, these metrics require an internal operating system view of the instance. The Monitoring tab (shown in the following image) shows the metrics that can be measured external to the instance (for example, CPU utilization, network bytes in/out). Amazon CloudWatch is an AWS monitoring service. If you open the Amazon EC2 console, select a running Amazon EC2 instance, and select the Monitoring tab you can see Amazon CloudWatch metrics for that instance. This post was written by Dean Suzuki, Solution Architect Manager.Ĭustomers who run Windows or Linux instances on AWS frequently ask, “How do I know if my disks are almost full?” or “How do I know if my application is using all the available memory and is paging to disk?” This blog helps answer these questions by walking you through how to set up monitoring to capture these internal performance metrics.
