The idea of monitoring Dynamics 365 or Model Driven Applications is not a new concept. Understanding where services are failing, users are interacting with the platform, where form and business processes could be tuned for performance are key drivers for most if not all businesses, from small companies to enterprises. Luckily, the Dynamics 365 platform provides many tools to help audit and monitor business and operational events.

This article will cover adding Azure Application Insights functionality to Power Apps Component Framework controls. In this article we will briefly touch on the subjects of Power Apps Component Framework and NPM packages. We will explore building and extending a sample Power Apps Component Framework control to send events to Azure Application Insights. We will conclude with context considerations and reviewing events.

What is Power Apps Component Framework?


"Power Apps component framework empowers professional developers and app makers to create code components for model-driven and canvas apps (public preview) to provide enhanced user experience for the users to work with data on forms, views, and dashboards."

Power Apps Component Framework Controls can be added to both Canvas and Model Driven Applications to extend the user experience beyond the standard controls available. Examples include grids behaving like maps, number controls turned into dials or sliders and even integrations with Azure Cognitive services.

Power Apps Component Framework Controls render in context of the Model Driven Application form unlike web resources and as such behave like other controls. Multiple Power Apps Component Framework controls can be added to a form. Power Apps Component Framework controls are solution aware and can be added and migrated across environments just like other components of a solution.

Application Insights JavaScript GitHub Repo


The official Azure Application Insights JavaScript GitHub Repository contains all the information needed to download and install the SDK for use within a Power Apps Component Framework control. The Getting Started section describes creating an Azure Application Insights resource and installing the correct NPM package.

Application Insights NPM Package


To install the Azure Application Insights NPM package, use the following command (I use Visual Studio Code's terminal):

npm i --save @microsoft/applicationinsights-web

Implementing Application Insights in a PCF Control


This section assumes you have already covered the basics for creating a PCF control. If not, please refer to the official documentation. The next two sections can also be found in the Azure Application Insights JavaScript SDK GitHub repo. I've adjusted the code slightly to take into account the way PCF controls render.

Add Application Insights Dependencies


In the index.ts file, we first need to import the Azure Application Insights module:

import { ApplicationInsights, IEventTelemetry } from '@microsoft/applicationinsights-web'

The next step is to add an instance of the ApplicationInsights object. I added mine to the PCF control class that allowed for use across the different methods used by PCF. That said you may choose to implement Azure Application Insights in another way, such as in the global namespace, so where and how you decide to create this object is up to the developer.

  pcfControlAppInsights = new ApplicationInsights({ config: {
    instrumentationKey: '',
    enableResponseHeaderTracking: true,
    enableRequestHeaderTracking: true
    /* ...Other Configuration Options... */
   } });

As shown above, various configuration properties can be set here. These include how often messages are sent, how long sessions last, if sampling should be used, etc. I'm including request and response header tracking in this example, but many others exist. For additional properties, review the ApplicationInsights-JS GitHub documentation.

Initialize Application Insights


Once the ApplicationInsights object has been created for use, the first step is to initialize the instance.


The Azure Application Insights module only expects to be loaded once, attempting to do so again could result in an error.

Error: Core should not be initialized more than once
    at AppInsightsCore.BaseCore.initialize (webpack://pcf_tools_652ac3f36e1e4bca82eb3c1dc44e6fad/./node_modules/@microsoft/applicationinsights-core-js/dist-esm/JavaScriptSDK/BaseCore.js?:46:13)
    at AppInsightsCore.initialize (webpack://pcf_tools_652ac3f36e1e4bca82eb3c1dc44e6fad/./node_modules/@microsoft/applicationinsights-core-js/dist-esm/JavaScriptSDK/AppInsightsCore.js?:33:33)
    at Initialization.loadAppInsights (webpack://pcf_tools_652ac3f36e1e4bca82eb3c1dc44e6fad/./node_modules/@microsoft/applicationinsights-web/dist-esm/Initialization.js?:299:16)

To account for this, the core includes a isInitialized method to help determine is the SDK has been loaded. To extend the previous example, include it within a conditional check:

   if (!this.pcfControlAppInsights.core.isInitialized!()){
    //Use this to load the app insights dependencies for use.

Once loaded, the Application Insights object can be used immediately to record page views, exceptions or any event that needs to be documented. To begin using and seeing an example, simply add a call to the trackPageView method which requires zero inputs.

//Send Page View Event

Usage across PCF Control Methods


PCF Controls have three main methods used within the lifecycle of a control consisting of the initialization of the control (init), changes to the control (updateView) and removal of the control (destroy). The usage of PCF controls vary greatly and other methods can be used for input output, HTML elements within the control, etc which will not be covered here. If you'd like to learn more, there are many great tools and open source projects that go into this at great length.

For this article just be aware that Azure Application Insights can be used to track virtually any callback with a control. Examples include user clicks of a button, responses from API calls, or as described above, when and how a control is created or initialized.

Here is an example of tracking a custom event within the initialize method:


Here is an example of tracking a custom event within the update view method:

Here is an example of tracking a custom event within the get outputs method:

Here is an example of tracking a custom event within the destroy method:

Configure Context


Adding context to Azure Application Insights messages is extremely important and vital to leveraging the robust feature set associated with the service. That said, out of the box, the SDK provides automatic context properties and allows developers the ability to overwrite. This provides the potential to select well known values or correlating identifiers such as form or entity Ids in Dynamics 365, system user Ids, Model Driven Application Ids and so on.

The image below shows a captured Fiddler trace of a default context properties.

To add or modify context for all messages sent to Azure Application Insights, use the addTelemetryInitializer method. This method provides the ability to pass in a custom envelope which can be extended to modify or extend properties of an Azure Application Insights message. Here, developers can set cloud role and instance, operation names and identifiers, and even custom properties that will be included in each record in the Azure Application Insights tables.

The first part of the code above creates an object that contains Azure Application Insights tags and custom properties. These tags will align with the session and operational context for each message sent from the PCF control.

var telemetryInitializer = (envelope) => {
    envelope.tags[""] = orgSettings._customControlExposedOrgSettings.organizationId;
    envelope.tags[""] = response;
    envelope.tags[""] = window.URL;
    envelope.tags[""] =; = 'just checking in';

In the sample code above the cloud role and instance are set to the Dynamics 365 organization and Model Driven Application identifier. The values used here will impact how the Application Map in Azure Application Insights renders.

The operation name is the class name of the PCF control. Operations include both the core operation and the parent, this could be thought of as the core operation being the event (initialization of the control) and the parent being the workblock (loading of the Dynamics 365 form).

Next, add the ITelemetryItem created above using the addTelemetryInitializer method:

//Add the context properties

To reiterate, setting the context, while desired for many reasons, is completely optional. Following the Implementing Application Insights in a PCF control section above will work just fine.

At this point session, role and operation data points have been set, one other point I'd recommend reviewing is adding the user identifier. This can be added as a custom property within the custom dimensions property bag but for this example we will use the Authenticated User property on the core ApplicationInsights object.

//Set user authenticated
this.pcfControlAppInsights.setAuthenticatedUserContext(context.userSettings.userId, undefined, true);

The sample code above uses the userId provided from the context for Model Driven Applications. Consider a different approach if working with Canvas Driven Applications.

Reviewing Application Insights


Once the control is implemented with a Model Driven Application, data will being to flow to Azure Application Insights. An interesting note here is that the Azure Application Insights SDK is also used by the platform. In some cases the events sent from your Model Driven Application may be delivered in the same envelope! Don't worry, this has no impact to the platform and will not break if the platform changes how it delivers messages.

Once delivered, user session and events will begin to appear. The below example shows the init method, followed by the updateview and getOutputs with user interaction in between.

Example of a custom event record:

This reference includes all the sample code above and additional usage showing how to send various events to Azure Application Insights.

Next Steps


In this article we have discussed how to add Azure Application Insights to Power Apps Component Framework controls. Continue exploring and evaluating how the initialization of the ApplicationInsights object can be extended with different properties, such as enableAutoRouteTracking

In an upcoming article, we will explore the tools within Azure Application Insights that rely on the context properties discussed at the end of this current article. Configuring both the actual delivery mechanism and adding context will help expose insights from the data collected.
