1. Define Monitoring Goals
According to a survey conducted by Amazon Web Services in 2021, 71% of IT decision-makers reported that monitoring and observability were the top cloud initiatives for their organizations.
But, in order to do that effectively, you need to sort out and define your monitoring goals first.
Focus on the following questions:
- What are you trying to achieve?
- What are your top priorities?
Once you have the answers, you can develop a monitoring strategy that outlines the metrics you’ll use to track the health of your systems.
What next? Have clear processes in place for responding to alerts and incidents. In case of incidents, you’ll need to quickly identify the root cause of the issue and take action before it escalates.
Create an incident response plan with well-defined steps you’ll take to minimize the impact of any issues.
2. Collect and Analyze Data from All Areas of Your AWS Environment:
Multiple Amazon services (and platforms) have different roles and specifications. Some might seem like a better fit for your needs, and some won’t. However, creating a monitoring plan that collects data from all areas of your AWS environment is essential.
With complete visibility, you can efficiently collect and analyze data, enabling you to quickly address multi-point failures as and when they occur. It’s important to have answers to basic monitoring questions to save time when navigating different areas of your cloud infrastructure. Some of these questions include:
- What resources are being monitored?

4. Automate Monitoring Tasks as Much as Possible
Automating monitoring tasks is an essential part of maintaining a stable and efficient AWS infrastructure. It lets you can free up valuable time for your team to focus on more strategic tasks and minimize the risk of human error.
Here are some tips to help you automate your monitoring tasks in AWS:
- Use AWS CloudFormation: It lets you define your infrastructure as code and automate the provisioning and configuration of your resources.
- Use AWS Lambda: A serverless computing service that lets you run code in response to events or triggers. You can automate monitoring tasks like log processing and data aggregation using AWS Lambda.
- Use AWS Config: This service allows you to track changes to your AWS resources and enforce compliance policies. You can use Config rules to automate monitoring tasks, such as checking for security vulnerabilities and resource misconfigurations.
- Leverage machine learning: Machine learning algorithms can help you detect patterns and anomalies in your data that may be difficult to identify manually. AWS offers a range of machine learning services, such as Amazon SageMaker and Amazon Rekognition, that can be used for monitoring and analysis.
5. Setup Alerts and Smartly Route Them to the Correct Person
Setting up alerts is a crucial aspect of AWS monitoring. It enables you to receive notifications at the time of incidents. This allows you to take quick action and resolve issues before it affects your end users.
Ensure that these alerts are routed to the right person or team. Here are some best practices for setting up alerts in AWS:
- Define appropriate thresholds for your alerts. They should be based on the specific requirements of your infrastructure. Setting too high or too low thresholds can lead to unnecessary alerts or missed critical issues.
- Configure notification preferences for alerts, including the method of notification (email, SMS, etc.), the recipient, and the severity level. Use AWS Simple Notification Service (SNS) to route notifications to multiple recipients or endpoints.
- Use escalation policies to ensure that alerts are routed to the appropriate person or team based on severity level or time sensitivity.
6. Check the Log Files on Your EC2 Instances
Checking log files on your EC2 instances is one of the important AWS monitoring best practices. Log files provide valuable information about your system events, errors, and application performance.
To check log files on EC2 instances, you can SSH into the instance and navigate to the relevant log files.
Collect the following log data:
- Database Logs: To detect slow queries.
- Application Logs: Understand the reasons behind application failure.
- AWS CloudTrail Logs: To detect API calls made to the application.
- OS Logs: To identify host-failure reasons.
- Web Server Logs: To capture firewall logs and VPC logs for patterns of access and attacks.
However, manually checking log files can be time-consuming and inefficient, especially in larger environments. That’s where log monitoring tools, such as Middleware, can come in handy.
To simplify the process, you can use tools like Middleware to collect log data from multiple sources, including EC2 instances, and provides centralized log analysis.
You can search, filter, and analyze log data, set up alerts and notifications, and quickly troubleshoot issues in your AWS environment.
