Setting Environment Variables

APPINSIGHTS_INSTRUMENTATIONKEY={App Insights Instrumentation Key}
CG_SENTIMENT_KEY={Cognitive Services Text Analytics Key}

Connecting to Code

var instrumentation = require('botbuilder-instrumentation');

// Setting up advanced instrumentation
let logging = new instrumentation.BotFrameworkInstrumentation({ 
  instrumentationKey: process.env.APPINSIGHTS_INSTRUMENTATIONKEY,
  sentimentKey: process.env.CG_SENTIMENT_KEY,
});
logging.monitor(bot);

Using mutiple instrumnetation keys

var instrumentation = require('botbuilder-instrumentation');

// Setting up advanced instrumentation
let logging = new instrumentation.BotFrameworkInstrumentation({ 
  instrumentationKey: ["main insturmnation key","secondary instumentation key"],
  sentimentKey: process.env.CG_SENTIMENT_KEY,
});
logging.monitor(bot);

Sending logs for QnA maker service

var instrumentation = require('botbuilder-instrumentation');

// Setting up advanced instrumentation
let logging = new instrumentation.BotFrameworkInstrumentation({ 
  instrumentationKey: ["main insturmnation key","secondary instumentation key"],
  sentimentKey: process.env.CG_SENTIMENT_KEY,
});
logging.monitor(bot);

//hook into the result function of QNA to extract relevant data for logging.
loggins.trackQNAEvent(context, userQuery, kbQuestion, kbAnswer, score);
//You can see a working sample in [https://github.com/Microsoft/BotBuilder-CognitiveServices/tree/master/Node/samples/QnAMakerWithFunctionOverrides](https://github.com/Microsoft/BotBuilder-CognitiveServices/tree/master/Node/samples/QnAMakerWithFunctionOverrides)

Sending custom event data

var instrumentation = require('botbuilder-instrumentation');

// Setting up advanced instrumentation
let logging = new instrumentation.BotFrameworkInstrumentation({ 
  instrumentationKey: ["main insturmnation key","secondary instumentation key"],
  sentimentKey: process.env.CG_SENTIMENT_KEY,
});
logging.monitor(bot);
let customEventName = 'myCustomEventName'; //This will show up as the event name in Application Insights.
let customEventData = { customeDataA: 'customValueA', customDataB: 3 };
logging.trackCustomEvent(context, customEventName, customEventData); //Custom key-value data. It will be avaiable under the customDimentions column in Application Insights.
