Export to Grafana Cloud

Atualizado em Ver como Markdown

Grafana Cloud is a fully managed observability platform that provides visualization, alerting, and analytics for your telemetry data. By exporting your Cloudflare Workers telemetry to Grafana Cloud, you can:

  • Visualize distributed traces in Grafana Tempo to understand request flows and performance bottlenecks
  • Query and analyze logs in Grafana Loki alongside your traces

This guide will walk you through configuring Cloudflare Workers to export OpenTelemetry-compliant traces and logs to your Grafana Cloud stack.

Prerequisites

Before you begin, ensure you have:

Step 1: Access the OpenTelemetry setup guide

  1. Log in to your Grafana Cloud portal ↗
  2. From your organization's home page, navigate to Connections → Add new connection
  3. Search for "OpenTelemetry" and select OpenTelemetry (OTLP)
  4. Select Quickstart then select JavaScript
  5. Click Create a new token
  6. Enter a name for your token (e.g., cloudflare-workers-otel) and click create token
  7. Click on Close without copying the token
  8. Copy and Save the value for OTEL_EXPORTER_OTLP_ENDPOINT and OTEL_EXPORTER_OTLP_HEADERS in the Environment variables code block as the OTel endpoint and as the Auth header value respectively

Step 2: Set up destination

  1. Navigate to your Cloudflare account's Workers Observability ↗ section
  2. Click Add destination and configure a destination name (e.g. grafana-tracing)
  3. From Grafana, copy your Otel endpoint, auth header, and auth value
  • Your OTEL endpoint will look like https://otlp-gateway-prod-us-east-2.grafana.net/otlp (append /v1/traces for traces and /v1/logs for logs)
  • Your custom header should include:
    • Your auth header name Authorization
    • Your auth header value Basic MTMxxx...

Step 3: Configure your Worker

With your destination created in the Cloudflare dashboard, update your Worker's configuration to enable telemetry export.

{
  "observability": {
    "traces": {
      "enabled": true,
      // Must match the destination name in the dashboard
      "destinations": ["grafana-traces"]
    },
    "logs": {
      "enabled": true,
      // Must match the destination name in the dashboard
      "destinations": ["grafana-logs"]
    }
  }
}
[observability.traces]
enabled = true
destinations = [ "grafana-traces" ]

[observability.logs]
enabled = true
destinations = [ "grafana-logs" ]

After updating your configuration, deploy your Worker for the changes to take effect.
