OpenTelemetry data model
When you enable OpenTelemetry, Altertable creates the catalog tables for you and exposes OTLP/HTTP endpoints that make ingestion easier. Accepted traces, logs, and metrics are written to normal SQL tables:
Table | Description |
|---|---|
opentelemetry.main.spans | Trace spans with service, timing, status, attributes, events, and links |
opentelemetry.main.metrics | Metric points joined with metric names, types, services, and series attributes |
opentelemetry.main.logs | Log records with severity, body, trace/span IDs, attributes, and resource attributes |
Query opentelemetry.main.metrics for metric values with their series attributes. The view joins the underlying metric_points and metric_series tables. Gauge and sum points expose value; histogram and summary points expose fields such as count and sum.
