The post outlines the process of streaming Graphite metrics to Grafana Cloud using carbon-relay-ng, a Go-based tool for aggregating, filtering, and routing metrics. It provides a step-by-step guide on setting up a Grafana Cloud instance, generating an API key, and configuring carbon-relay-ng to publish metrics. The configuration process includes setting up the carbon-relay-ng.conf file, ensuring correct user credentials and API key integration, and utilizing environment variables for security. It emphasizes the importance of matching storage schemas and highlights the capability to manage multi-instance and high-availability setups for scalability. Once configured, metrics can be queried through a Grafana Cloud instance, and users can create or import dashboards and set alerting rules. The post suggests importing a Carbon-relay-ng dashboard to monitor the tool's performance and directs users to further configuration documentation for advanced metric handling and alternative data destinations.
