help VictoriaMetrics FAQ

How does VictoriaMetrics compare to Prometheus for storing monitoring data?

VictoriaMetrics is designed as a highly scalable, cost-effective remote storage backend that is fully compatible with Prometheus. It offers significantly better data compression and can handle much higher cardinality metrics than standard Prometheus instances without requiring as much RAM.

Can I use VictoriaMetrics as a drop-in replacement for my existing monitoring stack?

Yes, VictoriaMetrics supports the Prometheus query API (PromQL) and can easily ingest data via Prometheus remote write. You can use the single-node `victoria-metrics` binary for smaller setups or the cluster version to scale horizontally.

Does VictoriaMetrics have built-in alerting and graphing tools?

Yes, the VictoriaMetrics ecosystem includes `vmalert` for executing alerting and recording rules based on PromQL or MetricsQL. It also offers `vmui`, a built-in web interface that allows you to query and visualize metrics without needing to set up Grafana.

Is VictoriaMetrics open source and free to use?

VictoriaMetrics is open source and released under the Apache 2.0 license, making it free for anyone to use and self-host. The company also offers a paid Enterprise version that includes advanced features like downsampling, backup automation, and multi-tenancy.
