We’re excited to introduce opensource vmestimator, a new component in the VictoriaMetrics ecosystem.

vmestimator measures metrics cardinality across arbitrary label dimensions and exposes the results as Prometheus-compatible metrics. It helps to understand where cardinality comes from, track how it evolves over time, and build early-warning alerts before cardinality becomes a problem.

If you’re operating Prometheus-compatible monitoring systems and want realtime visibility into metric cardinality, give vmestimator a try. We’d love to hear your feedback and learn more about your use cases.

Read more about its design and configuration in the documentation, or explore it yourself in the playground.
