botbuilder-telemetry

Build Status

Microsoft Botbuilder telemetry package for analytics. Allows bot session, incoming and outgoing messages, and LUIS recognizer to be captured and consumed. This payload can be sent to any endpoint desired. Microsoft Application Insights metrics can also be used with botbuilder-telemetry payload.

Telemetry Included (predefined body payload)

botName: string                                 // "Test-Bot"
userName: string                                // "Foo Bar"
userMessage: string                             // "hello"
userMessageLength: number                       // 5
userMessageTimestamp: string                    // 2017-10-26T20:21:54.977Z
botResponse: string[]                           // ["Hello! I am your friendly bot."]
botResponseLength: number                       // 10
botResponseTimestamp: string                    // 2017-10-26T20:21:57.424Z
botResponseLatency: number                      // 2447
currentDialog: {dialog: string, step: number}   // Object {dialog: "*:/", step: 0}
dialogStack: string[]                           // ["*:/", "*:/greeting"]
luisIntent: string                              // "greeting"

Usage Examples

Microsoft Application Insights Example

Usage

Step 1: Configuration Object (Required)

This allows any object to be passed into the middleware, which will be available within the dataMutationFuncOrPromise(). This is useful if you wish to pass in default values to the body payload.

Ex. If you require the botVersion to be included in the payload, you can specify the version in the configObject and add this property onto the body within the dataMutationFuncOrPromise().

Note: If you would like LUIS intents included in the payload, you must pass in the recognizer (see example/app.js)

Note: If you do not require any config variables, create an empty object and pass it in.

var configObject = {
  'botVersion': 'v3',
  // required for LUIS query/intent telemetry
  'luisRecognizer': luisRecognizer, 
  'foo': 'bar'
}

Step 2: dataHandleFunction (Required)

After the body has gone through dataMutationFuncOrPromise() (optional), it will be ready to send to any endpoint/api/storage you choose. You can create any request call within this function. This will be the last step in the sequence for this pipeline.

Ex. Sending the body to a test endpoint using node-fetch package.

function dataHandleFunction (body, session, messages, configObject) {
  fetch('https://testEndpoint.com', {
    method: 'POST',
    headers: {
      'Content-Type': 'application/octet-stream',
      'Subscription-Key': process.env.apiKey
    },
    body: body
  }).then(response => {
    return response.json()
  }).then(json => {
  // Read response JSON here...
    console.log(json)
  })
}

Step 3: dataMutationFuncOrPromise (Optional)

This function or promise allows any processing and manipulation of the body payload, based on the predefined body payload, session, messages, recognizer and configObject.

messages is the object response from the bot to user containing the text, options, attachments and other relevant information.

Note: If dataMutationFuncOrPromise() is not defined, the predefined body payload will not be mutated and passed straight to the dataHandleFunction(), step 3.

function dataMutationFunction (body, session, messages, configObject) {
    // The bot version - Managed by the bot developer
    // Add bot version to body if passed in through configObject
    if (typeof configObject.botVersion === 'undefined') { 
      body.botVersion = configObject.botVersion 
    }

    // Restrict user message to 100 characters and update body
    if (body.userMessage.length > 100) { 
      body.userMessage = body.userMessage.substring(0, 100)
    }
  }

Step 4: Apply middleware

This step is necessary to utilize this telemetry package. Make sure to apply the middleware right after you create your bot instance.

// from Microsoft botbuilder SDK
var bot = new builder.UniversalBot(connector) 

// Use botbuilder-telemetry package
bot = applyTelemetryMiddleware(bot, configObject, dataHandleFunction, dataMutationFuncOrPromise)

// ... Rest of your bot definition
