Application Performance Monitoring (APM)

Tooling that instruments applications to track transaction performance, errors, dependencies, and resource usage.

Definition

APM tools collect traces, metrics, and code-level diagnostics to pinpoint slow transactions and failing dependencies. Examples include Azure Application Insights, Datadog APM, New Relic, Dynatrace, and Elastic APM.

Example

APM shows that a slow endpoint is caused by an N+1 SQL query pattern.

Exam tip

On AZ-400, Application Insights is the APM answer for Azure-hosted apps.
