When monitoring Amazon EC2 instances, it's essential to focus on several key aspects to ensure optimal performance, reliability, and security of your cloud infrastructure. Here's what to look for when performing EC2 monitoring.

Key Metrics To Monitor in AWS EC2

To monitor the condition of your core infrastructure, you should monitor basic system-level metrics, regardless of how each of your instances is configured. Another important task is monitoring the degree to which demand and resource capacity align. 

Instance Health and Status Checks

Instance health and status checks are automated tests Amazon Web Services (AWS) performs to monitor the operational state of EC2 instances. These checks are crucial for verifying that an instance is reachable and functioning correctly within the AWS environment. There are two main types of status checks for AWS EC2 monitoring: system status checks and instance status checks.

1. System Status: Monitor system-level checks provided by AWS, which include network connectivity and instance reachability. Ensure these checks pass to confirm underlying infrastructure health.

AWS performs System Status checks every minute. The instance's system status is flagged as impaired if a check fails consecutively for a specified period (usually several minutes).

The following issues are instances of how system status checks may not succeed:

• Absence of network connectivity
• System power outage
• Problems with the physical host's software
• Physical host hardware problems that affect network reachability

The StatusCheckFailed System metric is increased when a system status check fails.

2. Instance Status: Monitor instance-specific checks to verify that the operating system and applications running on the instance are functioning correctly. These checks include checking reachability, monitoring system logs, and checking for any software or hardware issues.

AWS also performs instance status checks every minute. Like system status checks, consecutive failures over a period result in the instance's status being marked as impaired.

Issues that may lead to the failure of Instance Status Checks include the following:

• Ineffective system status checks
• Inaccurate networking or initial setup
• Worn-out memory
• Faulty file system
• Incompatible kernel 

On Windows, an instance status check displays a failure until the instance becomes available again, such as after an instance reboot or while a Windows instance store-backed instance is being packed.

The StatusCheckFailed Instance metric is incremented when an instance status check fails. 

Performance Metrics

Performance affects user experience, which in turn affects revenue. Slow page loads for web applications will cause users to leave, and some may never return. System performance should always be monitored since spikes in activity or times of high demand are often when it is most impacted.

1. CPU Metrics

The first metric affecting the instances' overall performance and health is CPU metrics. Here are all the CPU metrics with their details: 

• CPUUtilization: CPUUtilization measures the percentage of time that the CPU (Central Processing Unit) of an EC2 instance is busy processing instructions. It indicates how much of the CPU's processing capacity is utilized at any given time. CPU utilization is typically represented as a percentage (%) and can be monitored over different time intervals (e.g., every 5 minutes, hourly averages).
  You should track CPU usage to understand the workload demands on EC2 instances. High CPU utilization could indicate a need to scale up instance types or optimize applications.
• CPU Credit Metrics (T2/T3 Instances): AWS offers burstable performance instances (e.g., T2, T3) that accumulate CPU credits during periods of low usage. These credits are spent during bursts of CPU activity.
• CPUCreditUsage: CPUCreditUsage is a metric that measures the number of CPU credits consumed by an EC2 instance over a specific period.

What is its usage? 

• CPUCreditUsage increments when the instance consumes CPU resources beyond its baseline performance level (measured in CPU credits).
• Burstable instances accumulate CPU credits during periods of low CPU usage, which are then used during bursts of activity.
  Monitoring CPUCreditUsage helps understand how effectively an instance utilizes its CPU credits. It indicates whether the instance is operating within its baseline or consuming surplus credits during bursts of CPU activity.
  You can track CPUCreditUsage in AWS CloudWatch metrics to visualize and analyze CPU credit consumption. You can also set alarms based on thresholds to monitor usage patterns and ensure instances have sufficient credits to meet workload demands.

CPUCreditBalance: CPUCreditBalance represents the remaining CPU credits available for an EC2 instance at any given time.

When is it used? 

• Burstable instances like T2 and T3 give CPU credits when operating below their baseline CPU performance level.
• CPUCreditBalance decreases as CPU credits are consumed during bursts of CPU activity.

Monitoring CPUCreditBalance is crucial to ensure that burstable instances have sufficient credits to handle workload spikes effectively without performance throttling. You can monitor CPUCreditBalance alongside CPUCreditUsage in CloudWatch to assess the availability and depletion rate of CPU credits. Also, you can use alarms to alert when CPUCreditBalance drops below a specified threshold, indicating a potential need to scale instance types or adjust workload patterns.

CPUSurplusCreditBalance: CPUSurplusCreditBalance measures the accumulated surplus CPU credits available for a burstable instance beyond its baseline.

What is its usage? 

• Surplus CPU credits are accumulated when burstable instances operate below their baseline performance level and do not use their full allocation of accrued CPU credits.
• CPUSurplusCreditBalance reflects the surplus credits available for burstable performance beyond the initial baseline.

Tracking CPUSurplusCreditBalance provides insights into how efficiently burstable instances utilize surplus CPU credits during periods of low demand. You can monitor CPUSurplusCreditBalance to optimize resource usage and understand the efficiency of burstable instance performance. Also, this metric will be used to evaluate the effectiveness of instance sizing and workload management strategies.

CPUSurplusCreditsCharged: CPUSurplusCreditsCharged measures the number of surplus CPU credits consumed by an instance during a specific period.

What is its usage?

• Burstable instances use surplus CPU credits beyond their baseline during bursts of CPU activity.
• CPUSurplusCreditsCharged indicates the amount of additional CPU resources consumed beyond the baseline allocation of CPU credits.

Monitoring CPUSurplusCreditsCharged helps understand the impact of burstable performance on overall instance costs and resource utilization. You can track CPUSurplusCreditsCharged to analyze the cost implications of using surplus CPU credits for burstable instances. Use this metric to optimize cost management strategies and ensure efficient use of burstable instance capabilities.

Note: The last two metrics are exclusive to instances that have been set to unlimited. 

These AWS EC2 CPU metrics related to CPU credits (CPUCreditUsage, CPUCreditBalance, CPUSurplusCreditBalance, CPUSurplusCreditsCharged) are essential for monitoring and managing burstable performance instances like T2 and T3. By effectively monitoring these metrics through AWS CloudWatch, organizations can optimize instance performance, manage costs, and ensure that burstable instances operate efficiently within their CPU credit limits.
