PrometheusDataQuery kind

Both documentation generation and kinds schemas are in active development and subject to change without prior notice.

PrometheusDataQuery

Maturity: experimental

Version: 0.0

It extends DataQuery.

Property Type Required Description
expr string Yes The actual expression/query that will be evaluated by Prometheus
refId string Yes (Inherited from DataQuery)
A unique identifier for the query within the list of targets.
In server side expressions, the refId is used as a variable name to identify results.
By default, the UI will assign A->Z; however setting meaningful names may be useful.
datasource No (Inherited from DataQuery)
For mixed data sources the selected datasource is on the query level.
For non mixed scenarios this is undefined.
TODO find a better way to do this ^ that's friendly to schema
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)
true if query is disabled (ie should not be returned to the dashboard)
Note this does not always imply that the query should not be executed since
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)
Specify the query flavor
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.
