Dash0 Semantic Conventions

This repository contains the semantic conventions for Dash0. The conventions are defined using the OpenTelemetry Weaver registry format. They build on top of the OpenTelemetry Semantic Conventions.

The full registry documentation is published at dash0hq.github.io/dash0-semantic-conventions. This is a temporary location; the content will be merged into the Dash0 Docs in a future release.

Conventions

Attributes

• Resource — Resource identity and classification: dash0.resource.id, dash0.resource.hash, dash0.resource.name, dash0.resource.type.
• Operation — Operation naming and typing: dash0.operation.name, dash0.operation.type.
• Span — Span identity: dash0.span.name, dash0.span.type.
• Trace Origin — Trace origin classification and context: dash0.trace.origin.type, dash0.trace.origin.web.session.id, dash0.trace.origin.web.event.id, dash0.trace.origin.synthetic_check.check_id, dash0.trace.origin.synthetic_check.attempt_id, dash0.trace.origin.synthetic_check.follow_redirect.
• Log — Log enrichment: dash0.log.message, dash0.log.pattern, dash0.log.ai.attributes_inferred, dash0.log.ai.message_inferred, dash0.log.ai.severity_inferred.
• OTLP Field Mappings — Dash0-specific mappings of OTLP protocol fields to queryable attributes: otel.trace.id, otel.span.id, otel.parent.id, otel.span.name, otel.span.kind, otel.span.status.code, otel.span.status.message, otel.span.event.name, otel.log.body, otel.log.severity.number, otel.log.severity.range, otel.log.severity.text, otel.metric.name, otel.metric.type, otel.metric.unit, otel.metric.overflow.

Events

• Deployment Event (dash0.deployment) — Marks the deployment of a service version to an environment. Emitted once per deployment from CI/CD pipelines (e.g., a GitHub Action).

Metrics

• Tracing (dash0.spans, dash0.spans.duration, dash0.span.events) — Span counts, duration distributions, and span event counts.
• Logging (dash0.logs) — Log record counts.
• Metrics (dash0.metrics.datapoints) — Metric data point counts.
• Resources (dash0.resources) — Resource counts and resource-related attributes like dash0.resource.id.
• RED Metrics (dash0.spans.red) — Pre-aggregated Rate/Error/Duration exponential histogram over spans.
• Website Monitoring (dash0.web.*) — Web events, bounces, errors, page views, requests, sessions, users, and Core Web Vitals (CLS, INP, LCP).
• Synthetic Checks (dash0.synthetic_check.*) — Synthetic check runs and HTTP timing breakdowns (DNS, connection, SSL, request, response, total duration).
• Alerting (dash0.check.*, dash0.issue.*) — Check status, evaluation outcomes/values, and issue status.
• Dash0 Operator (dash0.operator.manager.*) — Kubernetes operator worker pools, reconcile counts, errors, and timing.
