Analyzing metrics usage with cardinality management dashboards

Grafana Cloud’s Pro and Advanced tiers include the ability to explore the cardinality of the metrics and labels stored inside of Grafana Cloud Metrics using a set of cardinality management dashboards.

These dashboards allow you to visualize the distribution of metrics and labels across your active time series stored in Grafana Cloud Metrics. See Active series and DPM for the definition of an active series.

Limitations

  • Cardinality analysis dashboards only display data for metrics and labels within a single stack.
  • The cardinality dashboards only work with default (provisioned by Grafana Cloud at the creation of a stack or org) Grafana Coud Prometheus data sources.

Dashboards

Grafana Cloud provides provides several, provisioned-by-default dashboards that allow you to visualize and explore the data. To find the dashboards:

  1. Go to Dashboard -> Browse in Grafana Cloud
  2. Filter by the cardinality-management tag
