OpenMetrics Explorer

OpenMetrics Explorer allows you to directly explore custom Prometheus-based metrics using PromQL, visualize them in various formats, and check the status of metrics or gain insights.

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

To use the OpenMetrics Explorer, the Open Agent must be installed.
