Application Performance Monitoring
APM traces a request across every service it touches, then keeps the profile, the logs and the host metrics attached to that same trace. You instrument once per service — with an agent for most languages, or manually where no agent exists — and the correlation comes from request context, not from you tagging things by hand.
