Node Metrics

This document provides a detailed guide on how to set up and use node metrics for monitoring a node's performance. The metrics are collected by the node and can be accessed through its REST API. Prometheus will be used to create a time series database from the data returned by the public node metrics, and Alertmanager will be set up and configured to send alert notifications via Matrix.

For a more comprehensive observability stack, refer to the official observability stack repository.

Getting Started

Generating a Prometheus Configuration

To generate a Prometheus configuration file, you can use the golang script provided in this repository. The script generates a configuration file based on a node provider identifier.

Generate a configuration file by running the following command:

go run main.go --node-provider-id="rbn2y-6vfsb-gv35j-4cyvy-pzbdu-e5aum-jzjg6-5b4n5-vuguf-ycubq-zae" --use-dashboard

The --use-dashboard flag is optional and generates a configuration file based on the node provider's dashboard. You can also run the script without the flag to generate a configuration file based on the registry what will be fetched from the main-net registry directly.

The --out flag can be used to specify the output file path. By default, the configuration file is saved in the current directory as prometheus.yml.

This Prometheus configuration file can be used in guides mentioned in the next section.

Setting up Prometheus and Alertmanager

  1. Follow the instructions in prometheus-config.md to set up Prometheus
  2. Follow the insturctions in alertmanager-matrix-config.md to set up Alertmanager with Matrix.
