What does APM measure?

APM, or Application Performance Monitoring, is a crucial tool that measures the performance and availability of applications. The primary focus of APM is to ensure that applications are running smoothly and efficiently. One of the key metrics APM tracks is errors. This includes monitoring for occurrences when an application fails to perform as expected, such as crashes, exceptions, and other types of malfunction that can degrade the user experience.

Measuring errors allows organizations to identify and resolve issues quickly, improving the overall reliability of their applications. By analyzing error rates, teams can pinpoint problem areas, understand their impact, and implement solutions to enhance application performance.

While memory, latency, and traffic are also important metrics in understanding application performance, the primary focus of APM lies in error tracking. This makes it essential for maintaining the quality of service and ensuring user satisfaction.
