## vmalert
vmselect is capable of proxying requests to [vmalert](https://docs.victoriametrics.com/vmalert.html)
when `-vmalert.proxyURL` flag is set. Use this feature for the following cases:
* for proxying requests from [Grafana Alerting UI](https://grafana.com/docs/grafana/latest/alerting/);
* for accessing vmalert's UI through vmselect's Web interface.
For accessing vmalert's UI through vmselect configure `-vmalert.proxyURL` flag and visit
`http://<vmselect>:8481/select/<accountID>/prometheus/vmalert/home` link.
