Term	Kind	Topic	What it is
APM Transaction Tracing	tool	Application Performance Monitoring	Instrumentation that attributes application latency and errors to specific code paths, database queries and external calls, usually with automatic tracing.
Application Performance Monitoring APM	tool	Application Performance Monitoring	Instrumentation that attributes latency and errors to code paths and dependencies inside a service — the layer between metrics and a profiler.
Application Performance Monitoring APM	tool	Observability	Instrumentation inside the application that attributes latency and errors to specific code paths, queries and dependencies.
Distributed Tracing	tool	Observability	Following one logical request across every service it touches by propagating a shared trace identifier and recording timed spans.
Distributed Tracing in Practice	tool	Distributed Tracing	Following one request across every service it touches — the only tool that answers "where did the time go" in a distributed system.
OpenTelemetry OTel	tool	OpenTelemetry	A vendor-neutral standard and toolset for generating, collecting and exporting traces, metrics and logs.
