How to integrate Azure App Insight into Node-Red?

Question

I want to collect some metrics from my Node-Red application using Azure App insight. I have already configured App functions and insight in Azure Resource Groups. I installed this library into my Node-Red application but I don't know how to use it and also I cannot find any guideline for that? Please let me know how can I properly integrate App insight into my Node-Red application? Thank you!

Answer 1

• You need to add the code which includes Instrumentation key of Application Insights.

• You can directly add the key in the settings.js file, which is available in the C:\Users\v****\.node-red Installed node-red path.

• Define the function of ApplicationInsights under Node Settings => functionGlobalContext

functionGlobalContext: {
    //Configure AppInsights
},

I have taken references from NodeJS SDK

• But configuring in settings.js will effect all the applications.

• If you want to configure it for your specific node-red app, check the below workaround.

• Create a basic flow with Inject and Debug nodes, connect Inject with Debug Node.

• And add a message by double clicking the Inject node => Deploy and check the output.

• Now add a new function node and include to configure Application Insights.

• Connect Function node with Inject and Debug.
