Exporting metrics to Prometheus

Document updated on Sep 15, 2019

Prometheus is an open-source systems monitoring and alerting toolkit.

The Opencensus exporter allows you push data to Prometheus. Enabling it only requires you to include in the root level of your configuration the Opencensus middleware with the prometheus exporter. Specify the port on which Prometheus is running, the namespace (optional), and Prometheus will start receiving the data.
