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.
