Glossary

The terms below are shared across every IAPM surface: 3D, Web, and Studio. Use them exactly as written.

For the 3D client's spatial vocabulary (the Core, the Diagnostics cube, photons, altitude, camera views), see Spatial Vocabulary, which names the objects and places specific to the 3D environment.

Telemetry

Term What it is
Trace The record of a single request as it moves through your services, tying together every operation that request triggered.
Span One operation within a trace (a service call, a query, a handler). A trace is a tree of spans.
Trace ID The identifier shared by every span and log belonging to the same request. IAPM keys a request's telemetry on its trace ID.
Log A timestamped record of a discrete event. Logs that carry a trace ID are correlated to that request.
Metric A numeric measurement captured over time (a rate, a count, a duration).
Telemetry The traces, metrics, and logs your instrumented application emits.

Instrumentation

Term What it is
Instrumentation Adding OpenTelemetry to your application so it emits telemetry to IAPM.
OpenTelemetry (OTel) The open standard IAPM builds on for traces, metrics, and logs.
OTLP The OpenTelemetry Protocol, the wire format your application uses to send telemetry to IAPM. See Instrument your application for the current endpoint.
API key The credential that authorizes your application to send telemetry to a specific grid.

Your data in IAPM

IAPM organizes your telemetry in a hierarchy:

Term What it is
Account Your organization's IAPM identity.
Tenant An organizational unit within your account (a company or department).
Environment A deployment stage (development, staging, production).
Grid The telemetry container for a single application. Your instrumented data flows into a grid, and each grid has its own API key. In the 3D client, the same word also names the temporal view you travel into to see that data; see Spatial Vocabulary.
Service An instrumented component that emits telemetry, drawn from the service.name on your spans.
Service graph Your services as nodes and the calls between them as edges.

This glossary covers the telemetry model. For subscription, plan, and billing terms, see Getting Started.

Assistant

Term What it is
Tessa The IAPM AI Assistant. Once your telemetry is flowing, Tessa answers questions about your system from what is actually in your data.
