Application Insights: Telemetry data will require HTTPS

Monday, November 28, 2016

From December 5, 2016, Azure Application Insights will no longer accept telemetry data sent using HTTP. Only HTTPS data will be accepted. This change is being made to improve security.

This change will affect your app only if it uses a very old version of the Application Insights SDK. All telemetry sent by recent versions uses HTTPS by default. About 1% incoming telemetry for Application Insights uses HTTP.

Here's what you can do:

  • Update the Application Insights SDK used by your servers and apps to the latest version. All versions from the last six months send HTTPS by default.
  • Check that your webpages use a recent version of the JavaScript SDK snippet. The correct snippet should include a reference to: https://az416426.vo.msecnd.net/scripts/a/ai.0.js
    A new version of the snippet is available from the Getting Started tab in your Application Insights resource in the Azure portal. (You can also get it from GitHub, but substitute your app’s instrumentation key.)
  • If you see a drop-in telemetry volume after December 5, update your server applications to use the latest version of the Application Insights SDK. (How to upgrade: ASP.NET, Java.)
