Observability

Cosmonic Control includes a suite of observability tooling:

  • Prometheus emits metrics signals at http://prometheus:9090, leveraging data generated by nats-surveyor to create dashboards for NATS activity.
  • Perses provides dashboards to the Cosmonic Control Console UI and through the Perses Dashboard, available on the Console service at the /_perses endpoint.

Perses is designed to be GitOps-friendly and facilitate a Dashboard-as-Code approach. See the Perses documentation for more information.

Perses access is managed by Cosmonic Control Console authentication.

Observability (Console)​

The Observability view in the Cosmonic Control Console displays Perses dashboards, including custom dashboards created in Perses.
