|

[VictoriaMetrics](https://github.com/VictoriaMetrics/VictoriaMetrics) implements MetricsQL -

query language inspired by [PromQL](https://prometheus.io/docs/prometheus/latest/querying/basics/).
|

MetricsQL is backwards-compatible with PromQL, so Grafana dashboards backed by Prometheus datasource should work
