OpenTelemetry
Outpost exposes key performance metrics via OpenTelemetry. All metrics are exported as histograms.
Setup
You can configure OpenTelemetry Collector to export metrics to your observability platform.
Enable OpenTelemetry in the Hookdeck Monitoring settings or with the Config API using the OTEL_SERVICE_NAME and OTEL_EXPORTER_OTLP_ENDPOINT variables.
Outpost uses the OpenTelemetry Go SDK and is configured via the standard OTEL_* environment variables documented in the OTel SDK configuration reference.
To enable metrics export, set OTEL_SERVICE_NAME and configure an exporter endpoint, for example:
OTEL_SERVICE_NAME=outpost
OTEL_EXPORTER_OTLP_ENDPOINT=http://otel-collector:4317
