Summary Table Metrics
Summary table metrics overview⚓︎
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.
Hydrolix metrics⚓︎
Use multiple components with a metric⚓︎
If more than one component uses a given metric, querying it will return results from all relevant components. You can restrict results to a specific component by adding a service keyword to your query.
For example, "process_open_fds{service="stream-peer"}".
Ingest peers⚓︎
For a list of all Hydrolix metrics, see All Metrics.
Each ingest method's peers has multiple containers. One container runs message acquisition, and the other is the indexer which indexes and completes enrichment jobs.
