Notas do Editor
- A 360 degree view on your applications
- Still in preview for a couple more months, probably GA end of Q1
- Old vs new version, lots of docs point to old
- The core is an instrumentation key Belongs to a resource group – grouping for spending, access etc
- Demo: QR-code dev/itpro Show portal Show stats Usage – page views Segment on OS
- Start with web
- VS2013 U3 has it built-in
- Add installs nuget and updates web.config Also gives an AI config file
- Applicationinsights.config
- VS shows that events are being sent Data immediately shows up in the portal
- Any web (or javascript-enabled) app can send telemetry
- Easy to access code from portal
- Client side data
- Currently the only way to monitor dependant resources (BLOB, HTTP, SQL)
- Install and choose what web apps to activate, will update config and restart IIS.
- Status Monitor adds monitoring of dependant resources, otherwise the same as
- IIS is required
- Outside-in web test
- Add your test – locations and criteria
- How can a 200-returning call keep failing? ALL resources must succeed for test to pass
- These limits will probably change soon
- Some glitches around hot hours for online banking
- Apps coming soon – but can still report telemetry to ASP.NET Application Insights-app with apps SDK.
- Debug mode reports continously, release mode sends upon NEXT resume. (if online, otherwise next time)
- Example of telemetry data
- Some common concepts
- Metrics is looking at lots of data at once (eg graphs) Diagnostics is per event
- Metrics explorer has filters
- Alerts on metrics
- Drilling down opens diagnostics search
- Eg you can follow a session.
- Custom telemetry is easy; events, exceptions and pageviews are most common. You can send properties too. Metrics are currently not shown in the Azure portal.
- Custom events are also easily accessible in the portal.
- Continuous export to storage container, nicely organized on type, json data.
- DEMO - storage xplorer - alerts - diagnostics search follow session filter - - banks?
- Of course continuous export allows you to keep ALL data.
- Bought by Microsoft fall 2014, will hopefully be a part of AI in the future
