The Big Picture - fluxcd/flux2 - Prometheus

Prometheus is an open-source monitoring and alerting system. It collects and stores time series data in a consistent format, allowing for efficient querying and alerting. Flux2, a GitOps tool, can be monitored using Prometheus to gain insights into its state and performance.

Flux2 Prometheus Metrics

Flux2 provides native support for Prometheus metrics, which can be used to monitor the state of the Flux components. These metrics can be used to set up monitoring for the Flux controllers. For a complete list of available metrics, refer to the Flux Prometheus metrics documentation.

Setting Up Monitoring with Prometheus Operator and Grafana

To set up monitoring for Flux2 using Prometheus, follow these steps:

1. Install Prometheus using the Helm chart from the Prometheus repository.
2. Verify the signature of the Helm chart stored in an OCI-compliant registry as an OCI artifact.
3. Set up the Prometheus Operator in your Kubernetes cluster.
4. Create a Prometheus rule file to scrape Flux2 metrics.
5. Configure the Prometheus Operator to scrape Flux2 metrics.
6. Set up Grafana to visualize the collected metrics.

For a detailed guide on setting up monitoring for Flux2 using Prometheus, refer to the Flux monitoring example repository.

Conclusion

Monitoring Flux2 using Prometheus provides valuable insights into the state and performance of your GitOps workflow. By setting up monitoring, you can ensure the reliability and availability of your applications, as well as gain operational insights to improve your development process.
