Monitoring and Analyzing Telemetry

  • [アーティクル]

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 in Business Central can be enabled on two different levels:

  • Environment-level telemetry
  • App/extension-level telemetry (for each app/extension installed)

Shows how Environment-level telemetry and App/extension-level telemetry works in Business Central AL

When telemetry is enabled on the environment level, telemetry is emitted to an Azure Application Insights resource for gathering data on operations that happen on the environment.

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 Microsoft AppSource apps. It gives extension publishers insight into usage of their apps/extensions and also allows them to find errors and performance issues before partners and customers report them.

Both online environments and on-premises instances can emit telemetry to Azure Application Insights.

Tip

As an AL developer, you can craft custom telemetry messages directly from AL using the Feature Telemetry codeunit in the System Application or by using the LogMessage Method.

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.

Note

For apps/extensions, see Sending Extension Telemetry to Azure 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 with Power BI

To make it simple to analyze Business Central telemetry, we've developed two Power BI apps available from the Microsoft commercial marketplace. One app is for telemetry on environments. The other one is for telemetry on apps/extensions (the telemetry defined in app.json). Both apps are free and open source but requires Power BI pro licenses to install.

For more information, go to Analyze and Monitor Telemetry with Power BI.

Analyze 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 set up alerts on telemetry events with various tools depending on your role.

If you're a project manager, product owner, or functional consultant, consider using the no-code tool Power BI Metrics for your alerting needs.

If you prefer more control, consider using one of these low-code tools for your alerting needs.

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

For more information, go to Alert on Telemetry.
