Integrating AWS Lambda with Metrics
Learn how to use metrics in AWS Lambda.
We'll cover the following...
Metrics in a software application are used to quantitatively measure and track various aspects of the application’s behavior, performance, and usage. Unlike traces and log messages, metrics tend to be fairly primitive data points that may include the following:
Counter: Incremented every time a specific event occurs.
Gauge: Shows the current state of something in the system (such as CPU usage) that can increase or decrease over time.
Duration: Shows how long a process took.
Importance of metrics
Metrics provide valuable data that helps developers, operators, and stakeholders understand how the application is performing, identify issues, make informed decisions, and optimize system resources. Here are some of the vital tasks that use metrics.
Performance monitoring: Metrics allow us to monitor the performance of our application in real time or historically. We can track response times, resource utilization, throughput, and other performance-related indicators to ensure our application meets its performance goals. ...
