Application performance monitoring

API APM is a set of practices and tools that focus on tracking, analyzing, and optimizing the performance of APIs. Using API APM helps you ensure that your API delivers a smooth, efficient, and reliable experience for consumers. Read on to learn about the critical topics of API APM, including API response time, error monitoring, end-to-end transaction tracing, and dependency tracking.

The response time of an API is a fundamental metric in API APM. It measures the time it takes for an API to respond to a request. Consumers have little patience for slow or unresponsive APIs. Therefore, monitoring and optimizing response time is crucial to ensuring that your API meets user expectations. Most APM tools, such as New Relic or Dynatrace, let you obtain a report of the response times of all the operations your API provides.

One of the key aspects of response time monitoring is setting response time thresholds. By defining acceptable response time limits...
