Azure application performance management service for monitoring live applications. Like having a personal trainer for your applications that tracks their health and performance.
Developers use Application Insights to identify slow database queries and optimize their web application performance.
Azure Application Insights is an APM/observability service focused on application telemetry (requests, dependencies, exceptions, traces, availability, and user behavior). AWS CloudWatch Application Signals provides application-level health and SLO-style views built on CloudWatch metrics/logs/traces. Google Cloud typically combines Cloud Monitoring (metrics/alerts) with Cloud Trace (distributed tracing) and Logging for similar outcomes. OCI APM provides end-to-end tracing and performance monitoring for applications running on OCI and beyond.
