issues; Learn continuously

#DNNConnect2016

Building successful apps is hard

Competition is fierceUser retention requires constant improvements to your apps and services

Constant evolutionWeb services & mobile apps need to evolve rapidly to survive & grow

Continuous delivery is hereMost major services like Microsoft, Facebook, and others push update as often as every day

Success requires data-drive decision makingMaking effective choices about your backlog requires deep understanding of your users behaviors and habits

Application Insights

Telemetry is collected at each tier: server backend, middleware, web service & browser

DNN and Application Insights

• What telemetry?• DNN Usage:

• Page views• Web requests• Event Log• Trace information (log4net)• Exceptions (including browser exceptions)• Dependencies:

• database calls• 3rd party services (SMTP, WebServices, etc.)

• Performance

DEMOIntegrating Application Insights on DNN Platform

#DNNConnect2016

Why is diagnostics hard?

• Diagnosing across the entire app stack is hard unless various perspectives are connected

Service Performance

• Transaction response time

• DB response time• Exceptions• CPU and memory

utilization• Data Center location

• Custom events• Custom dimensions• App KPIs• Conversion rates• Funnel, Cohort

analysis

• Response time• Errors• Geo location• Browser type and

version• Session

App/Business Metrics

Customer Experience

#DNNConnect2016

Out-of-the-box: “Proactive Insights”

#DNNConnect2016

Typical adhoc and iterative diagnostic process

Customer complains about an app issue

What is the

overall error

trend?

Is the error trend

unusual ?

What are the errors

broken by type?

What is the most frequent

error type?

How many

users are impacted

by this error?

Which set of user

are having

the worst experienc

e?

Look at a user

session to see

what this user did?

Did the users

actions cause any

unusual activity on the DB?

Slow response from DB. Dive into code….
