## PrometheusDataQuery
|
|
|
|
#### Maturity: [experimental](../../../maturity/#experimental)
|
|
#### Version: 0.0
|
|
|
|
|
|
|
|
It extends [DataQuery](#dataquery).
|
|
|
|
| Property | Type | Required | Description |
|
|
|--------------|---------|----------|--------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------|
|
|
| `expr` | string | **Yes** | The actual expression/query that will be evaluated by Prometheus |
|
|
| `refId` | string | **Yes** | *(Inherited from [DataQuery](#dataquery))*<br/>A unique identifier for the query within the list of targets.<br/>In server side expressions, the refId is used as a variable name to identify results.<br/>By default, the UI will assign A->Z; however setting meaningful names may be useful. |
|
|
| `datasource` | | No | *(Inherited from [DataQuery](#dataquery))*<br/>For mixed data sources the selected datasource is on the query level.<br/>For non mixed scenarios this is undefined.<br/>TODO find a better way to do this ^ that's friendly to schema<br/>TODO this shouldn't be unknown but DataSourceRef | null |
|
|
| `editorMode` | string | No | Possible values are: `code`, `builder`. |
|
|
| `exemplar` | boolean | No | Execute an additional query to identify interesting raw samples relevant for the given expr |
|
|
| `format` | string | No | Possible values are: `time_series`, `table`, `heatmap`. |
|
|
| `hide` | boolean | No | *(Inherited from [DataQuery](#dataquery))*<br/>true if query is disabled (ie should not be returned to the dashboard)<br/>Note this does not always imply that the query should not be executed since<br/>the results from a hidden query may be used as the input to other queries (SSE etc) |
|
|
| `instant` | boolean | No | Returns only the latest value that Prometheus has scraped for the requested time series |
|
|
| `queryType` | string | No | *(Inherited from [DataQuery](#dataquery))*<br/>Specify the query flavor<br/>TODO make this required and give it a default |
|
|
| `range` | boolean | No | Returns a Range vector, comprised of a set of time series containing a range of data points over time for each time series |
|
|
|
|
### DataQuery
|
|
|
|
These are the common properties available to all queries in all datasources.
|
|
Specific implementations will *extend* this interface, adding the required
|
|
properties for the given context.
