Why VictoriaMetrics instead of Prometheus?#

KOF uses VictoriaMetrics as the metrics backend, rather than Prometheus alone, for several reasons.

  • Scalability: VictoriaMetrics supports horizontal clustering for large multi-cluster environments.
  • Compression: VictoriaMetrics stores high-cardinality metrics efficiently.
  • Federation: VictoriaMetrics integrates cleanly with Promxy for cross-cluster queries.

We still use Prometheus at the collection layer, but long-term storage and query efficiency are handled by VictoriaMetrics.
