[SLIDE FROM MICROSOFT ONLINE TECH FORUM SESSION] Now that the applications are in the Cloud, developers must find ways to debug and interact with the production applications with minimal impact and maximal efficiency. Azure comes with a full set of tools and utilities that can be used to manage and monitor your applications. In this session, see how streaming logs work to monitor the production application in real time. We also show how Snapshot Debugging can be used to live debug applications.

Editor's Notes
- Why is working with production apps usually difficult? There are a number of reasons. It can be difficult to pull logs and data. Tracking sessions is complicated when there are multiple load-balanced instances. Tools may be scattered and hard to find and configure.
- This is an example dashboard. From one place you can (reiterate bullets here).
- This is an overview of how Application Insights works.
- Application insights provides intelligent performance monitoring, looking across the full stack and tracking performance through layers of dependencies.
- All of the data collected by Application Insights can be analyzed using a powerful built-in analytics query language.
- Application Insights automatically provides an application map that is generated based on observed dependencies between components of your application.
- With Application Insights, drilling into a transaction is possible with correlating tracing that maps the entire interaction from the browser down to the database.
- Log analytics provides query capabilities directly from the portal. It can be locked down with role-based security and features built-in algorithms for detecting anomalies and clusters in the data.
- The data provided by log analytics can be displayed as a table or in a variety of different chart formats. You can easily save queries to reuse later.
- Snapshot debugging is a powerful feature that allows you to debug your application in production.
- It is designed to support distributed applications.
- As with other Azure services, it supports role-based access control.
- Debugging locally is straightforward because there is typically one instance of the app running on a single server.
- The cloud complicates things. In production, you have multiple users each accessing your distributed application with instances spanning multiple servers. How do you debug a specific end-to-end experience?
- Snapshot debugging captures the unique callstack for a specific session so you can debug without having to understand which client or server was part of the end-to-end flow that resulted in an exception.
