Azure – Disable/Enable ApplicationInsights Telemetry dynamically

I implemented Application Insigths in the frontend applciation and I want to disable/enable it based on a variable that can change over the lifetime of the applications. (e.g. user declined Application Insights consent => Disable Telemetry)

What I tried is:

appInsights.appInsights.config.disableTelemetry = true

however if I try to enable it back setting disableTelemetry =false this is not working anymore.

Is anything else that I need to make to persist this change or is there another way of doing this?

    You could use a telemetry filter for that:

    var filteringFunction = (envelope) => {
  if (condition) {
      return false; // Do not send telemetry
  }

  return true; // Do send the telemetry
};

    Register the filter like this:

    appInsights.addTelemetryInitializer(filteringFunction);

    • While Peter’s answer is correct, I have different approach where instead of using telemetry filters we can stop the application insights object itself from starting to log to app insights.

    • Here in the following code based on the value of the variable a it will start the app insight service.

    • So, we will run appInsights.start(); only for a particular for value of variable a.

    import { createRequire } from  "module";
const  require = createRequire(import.meta.url);

let  appInsights = require('applicationinsights');

appInsights.setup("<Your connection String>")
    .setAutoCollectConsole(true, true);

var  a = 10 ;
if(a==10)
{appInsights.start();}

console.log("Hello World ");

    Here I am running the code twice but with different value of variable a.

    Here in application insights one log appear.
