5.1 — Enable Azure Monitor and Application Insights

[davidortinau]

Description

Configure Azure Monitor and Application Insights for production observability. Services export OpenTelemetry metrics, logs, and traces to Application Insights for centralized monitoring and alerting.

Dependencies

• Depends on 3.5 — Configure Azure Container Apps for services #52 (Container Apps)

Acceptance Criteria

• Aspire.Azure.Monitor.OpenTelemetry added to AppHost
• Services configured to export to Application Insights
• Application Insights resource provisioned via Aspire
• Alerting rules configured: error rate threshold, response time SLO, availability
• Dashboard created with key metrics: requests/sec, error rate, dependency latency
• Tested: logs, metrics, traces flowing to Application Insights
• Team can access dashboards and alerts

Technical Notes

• OpenTelemetry export via Application Insights SDK
• Metrics: request rate, response time, error rate
• Logs: structured logging already in place
• Traces: distributed tracing shows end-to-end request flow
• Alerting: send notifications on critical errors or SLA violations
