Monitoring and Observability

OpenCodeHub supports OpenTelemetry (OTLP) for logs and metrics, allowing you to stream data to any compatible backend (Grafana Cloud, Prometheus/Loki, Datadog).

Grafana Cloud Setup (Recommended)

This guide explains how to stream logs from OpenCodeHub to Grafana Cloud.

1. Get Credentials

1. Log in to your Grafana Cloud Portal.
2. Find your Stack and locate the “OpenTelemetry” or “OTLP” section.
3. Click “Configure”.

2. Configure Environment

You need three values for your .env file:

GRAFANA_OTLP_ENDPOINT The OTLP endpoint URL for your region.

• US: https://otlp-gateway-prod-us-central-0.grafana.net/otlp/v1/logs
• EU: https://otlp-gateway-prod-eu-west-0.grafana.net/otlp/v1/logs

GRAFANA_INSTANCE_ID Your numeric Instance ID (found in Loki/OTLP settings).

GRAFANA_API_KEY An Access Policy Token with logs:write scope.

3. Update Configuration

Add these to your .env file:

# Grafana Cloud OTLP Logging
GRAFANA_OTLP_ENDPOINT=https://otlp-gateway-prod-us-central-0.grafana.net/otlp/v1/logs
GRAFANA_INSTANCE_ID=123456
GRAFANA_API_KEY=glc_...

Restart your application (bun run dev or docker restart).

4. View Logs

1. Go to Grafana Explore.
2. Select Loki data source.
3. Query: {service_name="opencodehub"}.

Self-Hosted Loki

If you run your own Loki instance, point the endpoint to your local instance:

GRAFANA_OTLP_ENDPOINT=http://loki:3100/otlp/v1/logs
