OpenTelemetry
Outpost uses OpenTelemetry to expose key performance metrics. You need to bring your own OpenTelemetry target for the metrics to be produced and exported. These metrics are all exported in the form of histograms.
Outpost uses the OpenTelemetry Go SDK. This is configured using the OTEL_* environment variables that are documented here.
