OpenMetrics Explorer lets you explore Prometheus-based custom metrics through PromQL, visualize them in various formats, and check metric status or gain insights.

Use this feature to freely query desired metrics, extract meaningful data, or link to dashboards for continuous monitoring.

Note

To use OpenMetrics Explorer, the open agent must be installed.

Exploring PromQL

In OpenMetrics Explorer, you can execute PromQL and check results with various visualization options.

Graph

• Line: Default time series line graph

• Bar: Visualization in bar chart format

• StackBar: Stacked bar chart showing cumulative values

Table / Raw

• Table: Displays values of each time series sorted chronologically in a table

• Raw: View the Prometheus API response (JSON format) as-is

PromQL Syntax Support and Autocomplete

When entering metrics such as node_cpu_seconds_total or container_memory_usage_bytes, the autocomplete feature suggests metric and operator lists.

Label filtering in the {pod="example"} format is also supported.

Adding to Dashboard

Save queried PromQL queries as dashboard widgets to continuously monitor desired metrics.
