You can also use raw queries & regular expressions to extract anything you might need.
### 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.
Which means you have to use `=~` instead of `=` in your Prometheus queries. For example `ALERTS{instance=~$instance}` instead of `ALERTS{instance=$instance}`.
