type StackdriverExecutor

type StackdriverExecutor struct {
	// contains filtered or unexported fields

StackdriverExecutor executes queries for the Stackdriver datasource

func (*StackdriverExecutor) Query

func (e *StackdriverExecutor) Query(ctx context.Context, dsInfo *models.DataSource, tsdbQuery *tsdb.TsdbQuery) (*tsdb.Response, error)

Query takes in the frontend queries, parses them into the Stackdriver query format executes the queries against the Stackdriver API and parses the response into the time series or table format

type StackdriverQuery

type StackdriverQuery struct {
	Target   string
	Params   url.Values

	GroupBys []string
	AliasBy  string

StackdriverQuery is the query that Grafana sends from the frontend
