Inspect Metric Details

Clicking any metric row in the Metrics Explorer opens the Metric Sidebar — a detail panel that surfaces everything Dash0 knows about that metric without leaving the explorer.

Tip

Select View in Query Builder in the Overview tab to open the metric directly in the Query Builder. The data-preview query is pre-populated, giving you a ready-made starting point for further analysis, filtering, and aggregation.

The sidebar is organised into three tabs:

Overview

The default tab. It shows:

  • Description — the human-readable description attached to the metric definition, if one was provided by the instrumentation.
  • Data Preview — a read-only PromQL query and a live time-series chart, so you can immediately see the shape of the data. The query uses otel_metric_name and otel_metric_type label matchers and wraps the result in increase() for cumulative metrics. Select Explain to get a plain-language explanation of the query.
  • Dimension table — a list of all time-series returned by the preview query, with their resource and metric attributes.

Attributes

Lists all attribute keys and their observed values that contribute to the cardinality of this metric.

The tab badge shows the number of distinct attribute keys and the total number of unique values across all keys. Use this tab to understand what is driving cardinality.

Resources

Lists all resources that have reported this metric in the selected time range.

The tab badge shows the resource count. Use this tab when you want to know where a metric is coming from rather than what its values are.
