Understanding Metrics, Alarms, and Dashboards

Effective monitoring relies on understanding key concepts:

• Metrics: Measurements of various aspects of your resources (CPU utilization, disk space, network traffic).
• Alarms: Automated notifications triggered when metrics exceed or fall below predefined thresholds. They can alert you to potential issues.
• Dashboards: Visual representations of your metrics, alarms, and other data, allowing you to quickly assess the health of your systems.

{"AlarmName": "HighCPUAlarm", "MetricName": "CPUUtilization", "Threshold": 80}

Creating custom dashboards allows for a personalized monitoring experience.

Summary

• AWS offers robust monitoring capabilities through integrated services.
• Understanding metrics, alarms, and dashboards is crucial for effective monitoring.
• Proactive monitoring is key to maintaining performance and preventing outages.
