type PhlareDatasource

type PhlareDatasource struct {
	// contains filtered or unexported fields
}

PhlareDatasource is a datasource for querying application performance profiles.

func (*PhlareDatasource) CallResource

func (*PhlareDatasource) CheckHealth

CheckHealth handles health checks sent from Grafana to the plugin. The main use case for these health checks is the test button on the datasource configuration page which allows users to verify that a datasource is working as expected.

func (*PhlareDatasource) PublishStream

PublishStream is called when a client sends a message to the stream.

func (*PhlareDatasource) QueryData

func (*PhlareDatasource) RunStream

RunStream is called once for any open channel. Results are shared with everyone subscribed to the same channel.

func (*PhlareDatasource) SubscribeStream

SubscribeStream is called when a client wants to connect to a stream. This callback allows sending the first message.
