## tip
* BUGFIX: vmselect: fix accessing [Graphite APIs](https://docs.victoriametrics.com/#graphite-api-usage). The access has been broken in v1.66.0, because `/graphite/*` path prefix accidentally clashed with `/graph*` path prefix used for VictoriaMetrics UI (aka `vmui`).

[VictoriaMetrics Enterprise](https://victoriametrics.com/enterprise.html) supports [Graphite Render API](https://graphite.readthedocs.io/en/stable/render_api.html) subset
at `/render` endpoint, which is used by [Graphite datasource in Grafana](https://grafana.com/docs/grafana/latest/datasources/graphite/).
It supports `Storage-Step` http request header, which must be set to a step between data points stored in VictoriaMetrics when configuring Graphite datasource in Grafana.
When configuring Graphite datasource in Grafana, the `Storage-Step` http request header must be set to a step between Graphite data points stored in VictoriaMetrics. For example, `Storage-Step: 10s` would mean 10 seconds distance between Graphite datapoints stored in VictoriaMetrics.
