Application Insights Java In-Process Agent in Azure Spring Cloud (Preview)

This document explains how to monitor apps and microservices using the Application Insights Java agent in Azure Spring Cloud.

With this feature you can:

  • Search tracing data with different filters.
  • View dependency map of microservices.
  • Check request performance.
  • Monitor real-time live metrics.
  • Check request failures.
  • Check application metrics.

Application Insights provide many observable perspectives, including:

  • Application map
  • Performance
  • Failures
  • Metrics
  • Live Metrics
  • Availability

ARM Template

To use the Azure Resource Manager template, copy following content to azuredeploy.json.

    "$schema": "",
    "contentVersion": "",
    "resources": [
            "type": "Microsoft.AppPlatform/Spring",
            "name": "customize this",
            "apiVersion": "2020-07-01",
            "location": "[resourceGroup().location]",
            "resources": [
                    "type": "monitoringSettings",
                    "apiVersion": "2020-11-01-preview",
                    "name": "default",
                    "properties": {
                        "appInsightsInstrumentationKey": "00000000-0000-0000-0000-000000000000",
                        "appInsightsSamplingRate": 88.0
                    "dependsOn": [
                        "[resourceId('Microsoft.AppPlatform/Spring', 'customize this')]"
            "properties": {}


Apply ARM template with the CLI command:

  • For an existing Azure Spring Cloud instance:
az spring-cloud app-insights update [--app-insights/--app-insights-key] "assignedName" [--sampling-rate] "samplingRate" –name "assignedName" –resource-group "resourceGroupName"
  • For a newly created Azure Spring Cloud instance:
az spring-cloud create/update [--app-insights]/[--app-insights-key] "assignedName" --disable-app-insights false --enable-java-agent true --name "assignedName" –resource-group "resourceGroupName"
  • To disable app-insight:
az spring-cloud app-insights update --disable –name "assignedName" –resource-group "resourceGroupName"
