Application Insights for Node error and no console logs

Question

Hi,

Application Insights for Node in Azure portal shows error Configuration for Node is not available through the portal for this app because i) a different runtime stack was selected during creation or ii) we are unable to detect the runtime stack. Please refer to the document below. and I can't get console logs from Application Insights.

I've started from scratch and build sample node app https://learn.microsoft.com/en-us/azure/app-service/quickstart-nodejs?tabs=windows&pivots=development-environment-vscode and deployed it to Azure WebApp (Windows operation system, Node version 18). I can see the console.logs in log stream, but when I setup the Application Insights I get the following error.

But according to the documentation this should be displayed:

I've tried the troubleshooting described in: https://learn.microsoft.com/en-us/azure/azure-monitor/app/azure-web-apps-nodejs?tabs=windows#troubleshooting

Configuration:

ApplicationInsightsAgent_EXTENSION_VERSION: ~2
XDT_MicrosoftApplicationInsights_NodeJS: 1
WEBSITE_NODE_DEFAULT_VERSION: ~18
SCM_DO_BUILD_DURING_DEPLOYMENT: true

And the status should be running but is not.

I've tried to access logs from Web App -> Application Insights-> Logs and I can get requests, but no traces or AppServiceConsoleLogs.

Auto-instrumentation should be supported according to https://learn.microsoft.com/en-us/azure/azure-monitor/app/codeless-overview#supported-environments-languages-and-resource-providers

Thank you.

@Zundalek Zbynek , Following-up on this -

Application Insights Node.js Agent cannot be configured in portal, but it can be configured using JSON file, checkout this article for more info: https://github.com/microsoft/ApplicationInsights-node.js#configuration

JSON need to be part of app and use APPLICATIONINSIGHTS_CONFIGURATION_FILE to specify the path so Agent can find it. Please try this and let us know, we will be more than happy to assist you further.

Thank you Ajkuma for your help you've saved my day!

I'm still not able to make it run on Windows but I'm able to make it run on Linux at least!

I've set up Application Insights for Node through Azure FE:

But get no console logs so I've created a json file applicationinsights.json in home directory:

{
  "samplingPercentage": 100,
  "enableAutoCollectExternalLoggers": true,
  "enableAutoCollectConsole": true,
  "enableAutoCollectExceptions": true,
  "enableInternalWarningLogging": true,
  "enableInternalDebugLogging": true,
  "enableAutoCollectHeartbeat": true,
  "enableSendLiveMetrics": true
}

And set variable APPLICATIONINSIGHTS_CONFIGURATION_FILE to /home/applicationinsights.json as you suggested. It finally works without any problems now.

PS: It would be nice if other people don't have to spend hours to set up basic things like this because the documentation is not helpful at all.
