1.3 Configure diagnostics, monitoring, and analytics

Retrieve diagnostics data; view streaming logs; configure endpoint monitoring, configure alerts; configure diagnostics; use remote debugging; monitor Web App resources

1.3.1 Retrieve diagnostics data

Enable diagnostics logging for web apps in Azure App Service: https://docs.microsoft.com/en-us/azure/app-service-web/web-sites-enable-diagnostic-log

1.3.2 View streaming logs

Streming logs lar deg se i "real time" hva applikasjonen din driver med, hvis den har mulighet for å logge til konsoll.

Du kan akksessere streamin-logs gjennom Azure Web Portal under Log Streaming eller gjennom Azure Developer Consoll ( Vistual Studio).

Web Application Endpoint Monitoring has been removed from Azure since October 31, 2016.

The new, replacement functionality isApplication Insight Availability Tests

1.3.4 Configure alerts

Azure Metric Alerts kan settes opp slik vi kan få beskjed om applikasjonen vår oppfører seg på en bestemt måte, basert på regler vi har satt opp i forkant.

1.3.5 Configure diagnostics

Å konfigurere Diagnostics gjøres under Configure Diagnostics i Azure Web Portal.Her har man muligheten til å konfigurere følgende:

• Application Logging
  • Om man i det hele tatt skal logge
• Level
  • Hvor mye man skal logge
    • Error
    • Warning
    • Information
    • Verbose
• Application Logging (Blob)
  • Blob er en spesiell lagringsplass/type i Azure. Spesifisere om man vil skrive loggen til Blob Storage
• Web Server Logging
  • Om man vil ha logging fra Web Serveren (IIS). Her ser man aktivitet som individuelle GET-requests o.l

• Detailed Error Messages

  • Om man vil ha en stacktrace av error. (!usikker på denne, har ikke testet)
• • Failed request Tracing

1.3.6 Use remote debugging

To configure and remote debug your Microsoft Azure App Service Web App, you will need to perform the following:

• Have a Web App deployed to the Azure platform
• Attach the remote debugger to the Web App
• Confirm the remote debugger is attached to the W3WP process
• Set the break points
• Execute the process which is rendering the exception, performing slow or in an unexpected manner
• Debugging other technologies
