Cerberus

Cerberus lets you keep your metrics, logs, and traces in ClickHouse and go on querying them from Grafana with PromQL, LogQL, and TraceQL — as if Prometheus, Loki, and Tempo were still doing the work.

Postgres Is Enough

A curated directory of PostgreSQL extensions and tools that can replace specialized databases. Before adding Redis, Elasticsearch, Kafka, or MongoDB to your stack, see what Postgres can do.

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.
