How to export metrics from the Relay Proxy using Prometheus

Affected: All SDKs

Overview

Prometheus is an open-source monitoring system that collects and stores metrics as time series data. You can configure Relay Proxy to export its internal statistics and traces so that Prometheus can scrape them for visualization and alerting.

Solution

Here’s how to configure Relay Proxy to export metrics to Prometheus:

1. Add Prometheus to your Relay configuration

In your Relay configuration file (for example, relay-config.yaml) add Prometheus.

Example:

[Prometheus]
enabled = false
port = 8031
prefix = ""

2. Restart Relay Proxy
Apply the new configuration by restarting your Relay Proxy instance.

3. Configure Prometheus to scrape Relay Proxy
In your Prometheus configuration file (prometheus.yml), add a scrape job for Relay Proxy.

Example:

scrape_configs:
  - job_name: 'ld_relay'
    metrics_path: /metrics
    static_configs:
      - targets: ['your-relay-proxy.com:8030']
