OpenMetrics Explorer

OpenMetrics Explorer is a feature that allows you to directly explore custom metrics based on Prometheus using PromQL, visualize them in various formats, and check metric states or gain insights.

With this feature, you can freely query the metrics you need, extract meaningful data, or connect them to dashboards for continuous monitoring.

Note

To use OpenMetrics Explorer, you must install the Open Agent.

Exploring with PromQL​

In OpenMetrics Explorer, you can run PromQL queries and view the results with different visualization options.
