Prometheus in Hydrolix

The Hydrolix stack includes Prometheus, an open-source metrics database. Hydrolix continuously updates its Prometheus instance with metrics information.

You can query, view, and actively monitor this information using a stack's Grafana instance, or you can access it with your own monitoring platform. See Prometheus Integration for more information about setting up Prometheus with an external server.

Use the Prometheus UI

Prometheus has its own web-based UI.

This view is a basic metric view, suitable for quickly entering queries and seeing simple, graphed results. This feature is available in Hydrolix without any additional setup.

Navigate to https://<YourHostname>/prometheus to view dashboards.

For more information about Prometheus metric types, refer to the Prometheus documentation.
