## Reading data

VictoriaMetrics various APIs for reading the data. [This document briefly describes these APIs](https://docs.victoriametrics.com/url-examples.html).

### Grafana setup:

Create [Prometheus datasource](http://docs.grafana.org/features/datasources/prometheus/) in Grafana with the following url:

```url
http://<victoriametrics-addr>:8428
```

Substitute `<victoriametrics-addr>` with the hostname or IP address of VictoriaMetrics.

Then build graphs and dashboards for the created datasource using [PromQL](https://prometheus.io/docs/prometheus/latest/querying/basics/) or [MetricsQL](https://docs.victoriametrics.com/MetricsQL.html).
