Is there any downside to adding ApplicationInsights when it is not running?

Question

Hi all;

Most of the time I have Application Insights turned off (it's expensive). When it is off, will I have a performance hit if the following code is called at the start of my Blazor server app?

builder.Logging.AddApplicationInsights();

builder.Services.AddApplicationInsightsTelemetry(); 

thanks - dave

Hi there David Thielen

Thanks for using QandA platform

Hi David,

This should not cause a significant performance hit. The overhead is minimal because no telemetry data is being sent.

also check, There might be a small initialization overhead when the application starts.

Since telemetry is not being sent, the main performance impact of Application Insights is avoided.

In summary, i think the performance impact should be negligible when Application Insights is turned off.

If this helps kindly accept the response thanks much.
