Monitoring and Analyzing Telemetry

APPLIES TO: Business Central 2019 release wave 2 and later

Business Central emits telemetry data for various activities and operations on environments and apps/extensions. Monitoring telemetry gives you a look at the activities and general health of your environments/apps, so you can diagnose problems and analyze operations that affect performance. Azure Application Insights is a service hosted within Azure that gathers telemetry data for analysis and presentation. Whether running Business Central online or on-premises, you can set your tenants up to send telemetry to Azure Application Insights.

Environment-level and app/extension-level telemetry

Telemetry can be enabled on two different levels:

  • Environment

    Telemetry can be enabled for a Business Central online environment or on-premises Business Central Server instance. When enabled on the environment, telemetry is emitted to a single Azure Application Insights resource for gathering data on operations that happen on the environment.

  • App/Extension

    With the Business Central 2020 release wave 2 and later, telemetry can also be enabled on a per-extension basis. Enabling telemetry is done by setting an Azure Application Insights connection string in the app's manifest (app.json file). At runtime, certain events related to the app/extension are emitted to the Azure Application Insights resource. This feature targets publishers of per-tenant extensions or Appsource apps to give them insight into issues in their app/extension before partners and customers report them.

Both for environment-level and app-level telemetry, it's possible to craft custom telemetry messages directly from AL using the LogMessage Method. Learn more about AL at Programming in AL.

Enable Telemetry

To send telemetry data to Azure Application Insights, you must have an Application Insights resource in Azure. Once you have the Azure Application Insights resource, you can start to configure your environments and apps/extensions to send telemetry data to it. Learn more at Enable Sending Telemetry to Application Insights.

Control telemetry cost

Azure Application Insights is billed based on the volume of telemetry data that is sent (data ingestion) and how long time you want data to be available (data retention).

Check the Azure Application Insights documentation for up-to-date information on pricing at https://azure.microsoft.com/pricing/details/monitor/.

For more information, go to Control Telemetry Cost.

Viewing telemetry data

Telemetry from Business Central is stored in Azure Application Insights Logs in the traces and pageViews tables. You can view collected data by writing log queries using Kusto query language (KQL). Learn more at Logs in Azure Monitor and Overview of log queries in Azure Monitor.

For more information, go to Analyze Telemetry with KQL.

Setting up alerts on telemetry

If something happens in your environment or app that you need to act on, you can set up a system that sends you an alert. Azure Application Insights makes it easy to define such alerts.

You can use the following tools to define and set up alerts on telemetry events:

  • Azure Application Insights Alerts
  • Azure Logic Apps
  • Power Automate

All three approaches need a Kusto (KQL) query to define the alerting condition.

For more information, go to Alert on Telemetry.

Telemetry sample code

To make it easier to get started using Azure Application Insights with Business Central, samples of KQL code are available in the Business Central BCTech repository on GitHub.
