Challenges 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

Challenges 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

Challenges 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
