1. Application Insights Matteo Emili twitter.com/MattVSTS || mattvsts.blogspot.com
2. Who am I?  Visual Studio ALM MVP  Professional Scrum Master I  Systems Engineering Advisor @ Dell Software  Taunton Developers Meetup  London Microsoft DevOps User Group
3. Build- Measure-Learn  Did Waterfall work?  …yours is the answer   The trend is towards a flexible, iterative approach to product development  Build-Deploy-Release-Continuous <favourite buzzword>…and then what?
4. CD Cycle Monitor Operate Working software in production Value realization
5. Getting visibility on what actually happens  Is my application performing?  What about availability?  Are my users having a good experience?  Above all, you need better, faster and more direct feedback
6. It is different from logging  We are not talking about plain application logs  What user actions are meaningful to your business goals?  Is the telemetry data answering this question?  You need to have visibility on user events  Actionable insights are mapped into behaviours (what content is used, not how)  E.g.: when a user enters in a certain page/area, log on/off, Favourites, social stats, errors…
7. You won’t do that from scratch  You need to use an analytics provider  Azure Application Insights   The development experience must be unobtrusive at first and then customisable with an SDK
8. Basic availability Basic performance Application usage Custom telemetry
9. Demo
10. This is about the app, but what about the service?  Availability monitoring is still part of the process, and it cannot be delegated  Application Insights provides a very handy tool for that: Synthetic Monitors  They can be simple (ping) or complex (Web Tests)  Synthetic Monitors help quickly uncover the roots of live issues and minimise customer impact
11. Application Insights vs Operational Insights  Application Insights is aimed at developers, hence it exposes a minimum set of features for infrastructure monitoring  Synthetic Monitors provide an easy way of setting up a core infrastructure monitoring service  There is a complementary offer though, which is Operational Insights, aimed at system administrators
12. Demo  Web Test Multistep Synthetic Monitor
13. Recap  Information from your users’ behaviours is very valuable  You can easily react to problems and troubleshoot live issues  Service monitoring patterns are easily imported from Visual Studio  Zero maintenance service
