OpenMetrics Explorer

The OpenMetrics Explorer is a feature that lets you directly explore Prometheus-based custom metrics with PromQL and visualize them in various forms to check the state of your metrics or gain insights.

With this feature, you can freely query the metrics you want, extract meaningful data, or link it to a dashboard for continuous monitoring.

Note

OpenAgent installation is required to use the OpenMetrics Explorer.

Exploring with PromQL

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

Graph

• Line: Default time-series line graph

• Bar: Visualized as a bar graph

• StackBar: Stacked bar chart showing accumulated values

Table / Raw

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

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

PromQL Syntax Support and Autocomplete

When you enter a metric such as node_cpu_seconds_total or container_memory_usage_bytes, the autocomplete feature suggests a list of metrics and operators.

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

Adding to a Dashboard

You can save a queried PromQL query as a dashboard widget to continuously monitor the metrics you want.
