VictoriaMetrics is a fast, cost-effective and scalable monitoring solution and time series database.

It supports the Prometheus pull model and various push protocols (Graphite, InfluxDB, OpenTSDB) for data ingestion. It is optimized for storage with high-latency IO, low IOPS and time series with high churn rate.

For reading the data and evaluating alerting rules, VictoriaMetrics supports the PromQL, MetricsQL and Graphite query languages. VictoriaMetrics Single is fully autonomous and can be used as a long-term storage for time series.

VictoriaMetrics Single can easily handle 10M+ of active time series on a single instance. It is perfect for small and medium environments.
