Skip particular requests to be logged in Application Insights

Question

Hello!
I'm struggling with configuring Application's Insights Telemetry Client.
I have Headless Sitecore application with Vue on client side and Nodejs express that used as proxy.
Currently we have application insights in place but facing a lot of unnecessary requests and so it make some difficulties to collect metrics that we need.
I was following guidance to get rid of redundant requests to be logged in AI but get no luck.

Neither setAutocollectRequests or filtering out requests using TelemetryProcessor not solving the problem.

/// solution 1 
 appInsights
    .setup()
    .setSendLiveMetrics(true)
    .setAutoCollectRequests(false)
    .start();


/// solution 2
appInsights.setup().setSendLiveMetrics(true).start();
appInsights.defaultClient.addTelemetryProcessor(telemetryRequestProcessor);

function telemetryRequestProcessor(envelope) {
    const telemetryData = envelope.data.baseData;

    if (
        envelope.name.endsWith('Request') &&
        telemetryData.name &&
        (telemetryData.name.includes('/healthz/live') ||
            telemetryData.name.includes('/sitecore/service/HeartBeat.aspx') ||
            telemetryData.name.includes('/probe.txt'))
    ) {
        return false; // Prevent tracking this request
    }
    return true; // Track the request if the conditions aren't met
}

Node version 20.12.2
applicationinsights version 2.9.6

Could you please advice possible options to solve the problem?

Thanks!

Answer 1

Hello @Maksym Shportko

Regarding the first solution, setAutoCollectRequests(false) should disable automatic collection of requests, but it will not prevent requests from being logged if they are explicitly tracked.

Regarding the second solution, the telemetryRequestProcessor function should filter out requests that match the specified conditions.

However, the envelope.name property should be "Microsoft.ApplicationInsights.Request",

not "Request".

So, you can try updating the condition to envelope.name === "Microsoft.ApplicationInsights.Request".

If neither of these solutions work, you can try using the samplingPercentage configuration option to reduce the number of requests that are logged.

For example, you can set samplingPercentage to 50 to log only 50% of the requests.

This should get you started.
