Analyzing Azure Function Integration Telemetry
Azure Function integration telemetry gathers data about the success or failure of calls from Business Central to Azure Functions using the Azure Function module in the System Application.
Failed operations result in a trace log entry that includes a reason for the failure.

Sample KQL code
This KQL code can help you get started analyzing and alerting on request failures to Azure functions:
traces
| where timestamp > ago(5d) // adjust as needed
| where customDimensions.eventId == 'AL0000I7P'
| project timestamp
, aadTenantId = customDimensions.aadTenantId
, environmentName = customDimensions.environmentName
, environmentType = customDimensions.environmentType
, companyName = customDimensions.companyName
, requestStatusCode = customDimensions.alStatusCode
, functionHost = customDimensions.alFunctionHost
To learn more about how to setup alerting on Business Central telemetry, see Alert on Telemetry.
Authorization failed to Azure function
Occurs when the environment was scheduled to be updated, but it wasn't possible to start the update within the update window defined in the Business Central admin center. For more information about the update window in the admin center, see Managing Updates in the Business Central Admin Center.
