| `HTTP method` | Use either POST or GET HTTP method to query your data source. POST is the recommended and pre-selected method as it allows bigger queries. Change this to GET if you have a Prometheus version older than 2.1 or if POST requests are restricted in your network. |
| `Disable metrics lookup` | Checking this option will disable the metrics chooser and metric/label support in the query field's autocomplete. This helps if you have performance issues with bigger Prometheus instances. |
| `Custom Query Parameters` | Add custom parameters to the Prometheus query URL. For example `timeout`, `partial_response`, `dedup`, or `max_source_resolution`. Multiple parameters should be concatenated together with an '&'. |
| `Label name` | Add the name of the field in the label object. |
| `URL` | If the link is external, then enter the full link URL. You can interpolate the value from the field with `${__value.raw }` macro. |
| `URL Label` | (Optional) Set a custom display label for the link URL. The link label defaults to the full external URL or the name of datasource and is overridden by this setting. |
| `Internal link` | Select if the link is internal or external. In the case of an internal link, a data source selector allows you to select the target data source. Supports tracing data sources only. |
| `Label name` | (Exemplar configuration) Add a name for the exemplar traceID property. |
| `URL` | (Exemplar configuration) For external link, enter the full URL. You can interpolate the value from the field with `${__value.raw }` macro. |
| `URL Label` | (Exemplar configuration) Optionally, add a custom display label to override the value of the `Label name` field. |
| `Internal link` | (Exemplar configuration) Enable this option if the link is internal. For an internal link, the data source selector allows you to select the tracing data source. |
