Configure the Beyla internal metrics reporter

Configure the Beyla internal metrics reporter

YAML section: internal_metrics

This component reports internal metrics about the auto-instrumentation tool’s behavior. You can export these metrics using Prometheus or OpenTelemetry.

To export metrics with Prometheus, set exporter to prometheus in the internal_metrics section. Then set port in the prometheus subsection.

To export metrics with OpenTelemetry, set exporter to otel in the internal_metrics section. Then set an endpoint in the otel_metrics_export or grafana.otlp section.

Example:

internal_metrics:
  exporter: prometheus
  prometheus:
    port: 6060
    path: /internal/metrics

Configuration summary

exporter

Set the internal metrics exporter. You can use disabled, prometheus, or otel.

prometheus.port

Set the HTTP port for the Prometheus scrape endpoint. If you leave it unset or set it to 0, Beyla doesn’t open a Prometheus endpoint and doesn’t report metrics.

You can use the same value as prometheus_export.port (both metric families share the same HTTP server, but use different paths), or use a different value (Beyla opens two HTTP servers for the different metric families).

prometheus.path

Set the HTTP query path to fetch Prometheus metrics.

If prometheus_export.port and internal_metrics.prometheus.port use the same value, you can set internal_metrics.prometheus.path to a different value than prometheus_export.path to keep the metric families separate, or use the same value to list both metric families in the same scrape endpoint.
