### Using templated variables in queries
When the `Include All` option or `Multi-Value` option is enabled, Grafana converts the labels from plain text to a regex compatible string. If your labels include special values such as `.` or `/`, you will need to use the `=~` or regex match in your Prometheus query. For example, a query for ALERTS, a template query of `label(ALERTS,instance)` and an instance value of `http://example.com` would become `ALERTS{instance=~$instance}` instead of `ALERTS{instance=$instance}`.
