New Relic Roku Agent

The New Relic Roku Agent tracks the behavior of a Roku App. It contains two parts, one to monitor general system level events and one to monitor video related events, for apps that use a video player.

Internally, it uses the Event API to send events using the REST interface. It sends two types of events: RokuSystem for system events and RokuVideo for video events. After the agent has sent some data it will be accessible in NR One Dashboards with a simple NRQL request like:

SELECT * FROM RokuSystem, RokuVideo

Will result in something like the following:

Call NewRelic from Main subroutine and store the returned object.
Right after that, call nrAppStarted (optional but recommended).
Call NewRelicSystemStart and NewRelicVideoStart to start capturing events for system and video (both optional).
Inside the main wait loop, call nrProcessMessage (only mandatory to capture system events, otherwise not necessary).

Example

Note: For a more complete example, please refer to the sample app included in the present repository. Specifically files Main.brs and files inside components directory.

Main.brs

sub Main(aa as Object)
	screen = CreateObject("roSGScreen")
	m.port = CreateObject("roMessagePort")
	screen.setMessagePort(m.port)

	'Create the main scene that contains a video player
	scene = screen.CreateScene("VideoScene")
	screen.show()
	    
	'Init New Relic Agent
	m.nr = NewRelic(“ACCOUNT ID“, “API KEY“)
	    
	'Send APP_STARTED event
	nrAppStarted(m.nr, aa)
	    
	'Pass NewRelicAgent object to the main scene
	scene.setField("nr", m.nr)
	    
	'Activate system tracking
	m.syslog = NewRelicSystemStart(m.port)
    
	while (true)
		msg = wait(0, m.port)
		if nrProcessMessage(m.nr, msg) = false
			'It is not a system message captured by New Relic Agent
			if type(msg) = "roPosterScreenEvent"
				if msg.isScreenClosed()
					exit while
				end if
			end if
		end if
	end while
end sub

Ad Tracking

The Roku Video Agent also provides Ad events monitoring. Currently we support two different Ad APIs: Roku Advertising Framework (RAF) and Google IMA.

Installation

For RAF there is no additional steps required, because the tracker is integrated inside the NRAgent, but for IMA, the following files must be included in the project:

RAF Usage

First we have to pass the NRAgent object (created with the call to NewRelic(accountId, apiKey)) to the Ads Task. This can be achieved using a field. Once done, inside the Ads Task we must do:

adIface = Roku_Ads()

' Ad Iface setup code...

logFunc = Function(obj = Invalid as Dynamic, evtType = invalid as Dynamic, ctx = invalid as Dynamic)
    'Call RAF tracker, passing the event and context
    nrTrackRAF(obj, evtType, ctx)
End Function

' m.top.nr is the reference to the field where we have the NRAgent object
adIface.setTrackingCallback(logFunc, m.top.nr)

For a complete usage example, checkout files VideoScene.brs (function setupVideoWithAds()) and AdsTask.brs in the present repo.

IMA Usage

First we have to create the IMA Tracker object:

tracker = IMATracker(m.nr)

Where m.nr is the NRAgent object.

Then we need to pass the tracker object to the IMA SDK Task, using a field. And include the script IMATrackerInterface.brs in the task XML.

Once done, inside the task we must do:

m.player.adBreakStarted = Function(adBreakInfo as Object)
	'Ad break start code...
	    
	'Send AD_BREAK_START
	nrSendIMAAdBreakStart(m.top.tracker, adBreakInfo)
End Function
m.player.adBreakEnded = Function(adBreakInfo as Object)
	'Ad break end code...
    
    'Send AD_BREAK_END
    nrSendIMAAdBreakEnd(m.top.tracker, adBreakInfo)
End Function

'...

m.streamManager.addEventListener(m.sdk.AdEvent.START, startCallback)
m.streamManager.addEventListener(m.sdk.AdEvent.FIRST_QUARTILE, firstQuartileCallback)
m.streamManager.addEventListener(m.sdk.AdEvent.MIDPOINT, midpointCallback)
m.streamManager.addEventListener(m.sdk.AdEvent.THIRD_QUARTILE, thirdQuartileCallback)
m.streamManager.addEventListener(m.sdk.AdEvent.COMPLETE, completeCallback)

Function startCallback(ad as Object) as Void
	'Send AD_START
	nrSendIMAAdStart(m.top.tracker, ad)
End Function

Function firstQuartileCallback(ad as Object) as Void
	'Send AD_QUARTILE (first)
	nrSendIMAAdFirstQuartile(m.top.tracker, ad)
End Function

Function midpointCallback(ad as Object) as Void
	'Send AD_QUARTILE (midpoint)
	nrSendIMAAdMidpoint(m.top.tracker, ad)
End Function

Function thirdQuartileCallback(ad as Object) as Void
	'Send AD_QUARTILE (third)
	nrSendIMAAdThirdQuartile(m.top.tracker, ad)
End Function

Function completeCallback(ad as Object) as Void
	'Send AD_END
	nrSendIMAAdEnd(m.top.tracker, ad)
End Function

Where m.top.tracker is the tracker object passed to the task.

For a complete usage example, checkout files VideoScene.brs (function setupVideoWithIMA()) and imasdk.brs in the present repo.

Testing

To run the unit tests, first copy the file UnitTestFramework.brs from unit-testing-framework to source/testFramework/. Then install the demo channel provided in the present repo and from a terminal run:

./test.sh ROKU_IP

Where ROKU_IP is the address of the Roku device where the channel is installed. Connect to the debug terminal (port 8085) to see test results. You can also provide the dev password as a second argument if you want to compile and deploy before running tests.

Debugging

Network proxying is supported using URL re-write (see App Level Proxying). To send all network requests via a proxy call nrUpdateConfig() function with the proxyUrl parameter object property. Be sure to specify the same URL delimiter as your proxy re-write rule.
