As a part of creating your bot, Azure Bot Service also provisions an instance of Application Insights using the Basic tier and will appear in your Azure subscription. Azure Bot Service is then configured to send diagnostic events and other telemetry for your bot, and is used to power the analytics page. Learn more about Bot Service analytics.
During bot creation, you choose an Azure Bot Service template that is most appropriate for your scenario. Depending on which template you use for your Bot, Azure Bot Service may need to provision an instance of the Cognitive Service LUIS or QnA Maker. Both are created using free/trial tiers and will appear in your Azure subscription.
