Telemetry is a specification to instrument all the key events. Using this specification reference applications & services will generate telemetry events. For more info here

Telemetry spec

Please refer the below link to know more about telemetry specification

Specification | Sunbird Telemetrytelemetry.sunbird.org

Pdata

This describes the producer data of the event, and also it has the details about the producer id, version of the app, and instances of the component. below is the sample pdata.

    "pdata": {
      "id": "sunbird.portal", // Producer ID. For ex: For sunbird it would be "portal" or "genie"
      "ver": "3.2.12", // Version of the App
      "pid": "sunbird-portal.contentplayer" // Optional. In case the component is distributed, then which instance of that component
    },    

Below are the list of sample pdata configs for different clients

Client	id	pid	ver
Mobile	sunbird.mobile	sunbird.mobile.contentplayer	<mobile app version>
Portal	sunbird.portal	sunbird.portal.contentplayer	<portal version>
Desktop	sunbird.desktop	sunbird.desktop.contentplayer	<desktop app version>

List of Events

Below are the list of events generating by players while launching irrespective of Mobile/Portal/Desktop application.

Start Event

This method initializes capture of telemetric data associated to the start of user action . Using the start event we can analysis time taken to start player. For more info here

following is the sample telemetry edata

"edata": {
  "type": "content", // Defines edata type(app, session, editor, player, workflow, assessment)
  "mode": "play", // Mode of start.
  "pageid": "", // Page/Stage id where the start has happened.
  "duration": 7.47 // Time taken to initialize/start
}

Impression Event

This method is used to capture user interactions on a page. For example, search, click, preview, move, resize, configure and the following is the sample telemetry edata. For more info here

"edata": {
  "type": "TOUCH", // Type of interaction TOUCH,DRAG,DROP,PINCH,ZOOM,SHAKE,ROTATE,SPEAK,LISTEN,WRITE,DRAW,START,ENDCHOOSE,ACTIVATE,SHOW,HIDE,SCROLL,HEARTBEAT,OTHER
  "subtype": "", // Additional types for a global type. For ex: for an audio the type is LISTEN and thesubtype can be one of PLAY,PAUSE,STOP,RESUME,END
  "id": "gc_menuopen", // Resource (button, screen, page, etc) id on which the interaction happened - use systemidentifiers when reporting device events
  "pageid": "2" // Stage or page id on which the event happened
}

interact Event

This method is used to capture telemetry for user visits to a specific page. and the following is the sample telemetry edata. For more info here

"edata": {
  "type": "workflow", // Impression type (list, detail, view, edit, workflow, search)
  "subtype": "", // Additional subtype. "Paginate", "Scroll"
  "id": "gc_menuopen", // Defines edata id
  "pageid": "2" // Unique page id
  "uri": "", // Required. Relative URL of the content
}

End Event

This method is used to capture closure after all the activities are completed. it also capture the content played details like total number of pages , progress, duration of play and etc and the following is the sample telemetry edata. For more info here

"edata": {
   "type": "content", // Defines edata type
   "mode": "play",   // Defines mode
   "pageid": "sunbird-player-Endpage", // Defines page id
    "summary": [
          {
            "progress": 22
          },
          {
            "totallength": 9
          },
          {
            "visitedlength": 2
          },
          {
            "visitedcontentend": false
          },
          {
            "totalseekedlength": 7
          },
          {
            "endpageseen": false
          }
        ],
    "duration": 11988.53 // Defines duration of play
}

Access Event

This method is used to capture user assessments that happen while playing content.For more info here

Response Event

This API is used to log telemetry of user response. For example; Responded to assessments.For more info here
