Application InsightsAvailability, Performance and Usage

Today we will coverUnderstanding Application Insights

Ensure your apps are available, performing & succeeding

Getting started with Application InsightsEasy onboarding with Visual Studio & Status Monitor

Solving problems with Application InsightsIdentify, triage & diagnose service failures & performance issues; Learn continuously

Bridge the gap between developers and operations

Monitoring tools for developers see CPU, network, memory, etc. Monitoring tools for Ops see performance and availability of custom production applications

Understanding Application Insights

Is my application Available, Performing, Succeeding

“By 2017, 94.5% of downloads will be for free apps; Less than 0.01% of consumer mobile apps will be considered a financial success” -Gartner

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(top teams update to production 72 times per day)

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

Building successful apps is hard

1. Telemetry is collected at each tier: Mobile

applications, server applications and browser

2. Telemetry arrives to Application Insights service

where it is processed & stored

3. Get 360° view of the application covering

Solving problems with Application Insights

Identify, triage & diagnose failures; Learn continuously

Identify & Triage issues: AvailabilityChallenges

• Visibility to application health?

• Visibility to application outages to minimize customer impact?

• Hard to get information to determine impact of issue?

Solutions• Reduce ‘Mean Time to Detect’

• Ensure service availability with 8 global points of presence

• URL ping tests and rich multi-step web tests

• Threshold based alerts on metrics and perf. counters

• Real time alerts via email

Diagnose & Solve problems: PerformanceChallenges

• Uncover root cause of production issues?

• Quickly resolve code problems detected in production?

Solutions• Reduce ‘Mean Time to Resolve’

• Identify issues with request rate & dependency response times

• Multi-dimensional analyses over custom & default metrics

• Drill through exceptions & failed requests with traces & runtime telemetry

Learn & Improve continuously: UsageChallenges

• Lack of information to prioritize future investments?

Solutions• Understand key adoption trends

• Prioritise investments & support specific client environments

• Custom event instrumentation & client page views

• Correlate usage with perf. telemetry for 360° view

Implementing Common Scenarios with the SDK

Add Application Insights SDK

SDK Best PracticesAPI Collected by Default? When to Use

Track Page View Yes with JavaScript SDK Want to differentiate with SPA

Track Request Yes with Server SDK

Track Event No Business/Feature usage logging

Track Trace No System logging, treat like your event log

Track Exception Yes but only at HTTP Module with Server SDK

Only exceptions you care about

Track Metric No Performance counters, business metrics

“Titanfall delivers an unparalleled multiplayer gaming experience, powered using Azure”• Uses data centers all over• The game figures out where you are• Where the closest Azure data center is• Spins up a server just for you – constantly available set of

servers• AI & NPCs(non-player characters) powered by server• More than 100,000 virtual machines deployed on launch day

...so there is no host advantage in this multiplayer game
