APM Service Dependencies

This tool answers "how is my application wired together?" It returns the APM dependency graph — a set of directed edges from caller services to callee services, with protocol (http, grpc, dns, etc.), call volume, and per-service health (span count, latency, errors) when requested.

Prerequisites

• Elastic APM with OTel-instrumented services producing span.destination.service.resource values.
• Optional: Kubernetes metadata on the spans (for namespace filtering).

If the user is log-only or metrics-only (no APM), this tool won't work. Do not reach for it.
