Substrate Prometheus Exporter

Introduction

Prometheus is one of the most widely used monitoring tools for managing highly available services supported by Cloud Native Computing Foundation. By providing Prometheus metrics in Substrate, node operators can easily adopt widely used display/alert tools such as Grafana and Alertmanager. Easy access to such monitoring tools will benefit parachain developers/operators and validators to have much higher availability of their services.

Metrics will be served under /metrics on TCP port 9615 by default.

Quick Start

From the root of the repository start Substrate cargo run --release.
In another terminal run curl localhost:9615/metrics to retrieve the metrics.

To learn how to configure Prometheus see the Prometheus Getting Started guide.
