Monitoring

Supermetal records metrics, logs, and traces through OpenTelemetry (OTel), exported over OTLP to Datadog, Splunk, or any OTel compatible backend. An opt in Prometheus endpoint serves the metrics. The full metrics reference covers data flow, latency, buffer activity, connector health, and the underlying process and runtime.

OTLP export

Set the standard OpenTelemetry environment variables where the agent runs.

OTEL_EXPORTER_OTLP_ENDPOINT=http://localhost:4317
OTEL_EXPORTER_OTLP_HEADERS="Authorization=Bearer <token>"

The OTLP exporter reference documents the full set.

Prometheus

The Prometheus endpoint is opt in. Set the PROMETHEUS environment variable and the agent serves metrics in Prometheus text format at /metrics on the server port.
