Overview of querying
When you create dashboards, monitors, or use the Metrics Explorer, you use a query to select and filter the metrics in which you're interested, and then apply functions to them.
Chronosphere Observability Platform supports these languages for querying metrics data:
- Prometheus Query Language (PromQL): Used with Prometheus-compatible metrics. Default.
- Graphite: Used with StatsD metrics data. Enabled on request.
Contact Chronosphere Support to set up the data sources you want to use.
To toggle the query language in use, use the method based on what you're working on:
- Dashboards: Use the language toggle in the Query panel of a dashboard.
- Monitors: Use the language toggle by the Query box.
- Metrics Explorer: Use the language toggle to the right of the Explore page title.
Although Chronosphere supports both PromQL and Graphite, this document provides information only about the use of PromQL. For more details about Graphite, see the Graphite documentation (opens in a new tab).
Additional features
Observability Platform also provides querying features beyond those covered by using query languages in its user interface.
- Delta queries: Query metrics that employ delta temporality, as opposed ot cumulative temporality.
- Prometheus API access: Interact directly with Prometheus API endpoints for programmatic workflows.
