The prometheus exporter is an open component of OpenTelemetry for exporting collected metrics over the HTTP server and publishing them on the /metrics page in the format of the Prometheus monitoring system. This exporter is the easiest to use — it does not require any external component configuration and can be enabled by default.

The otlphttp exporter is an open component of OpenTelemetry for exporting collected metrics to an OTLP-compatible storage or monitoring system that has to be predeployed and accessible. otlphttp uses the HTTP protocol.

Each component, depending on its type, should be added to the receivers, processors, or exporters section accordingly, and configured if necessary. The component configuration depends on the database instance setup and the log format used (see the logging_collector and log_destination parameters).
