Monitoring

Overview Dashboard​

Arbeidsflate's monitoring dashboards are hosted in Grafana and provide comprehensive insights into system performance, health metrics, and operational status. The dashboards are accessible at Grafana Altinn Cloud.

Main Metrics​

  • System Health: Availability, request stats, latency
  • Container Apps: CPU, memory, requests (GraphQL, app gateway)
  • Infrastructure: PostgreSQL, Redis

Usage​

  • Select environment (test, yt01, staging, prod)
  • Default view: Last 24 hours
  • Start with system health, then drill down as needed

Telemetry Collection​

Arbeidsflate uses OpenTelemetry for collecting and routing telemetry data:

OpenTelemetry Integration​

  • Utilizes Azure Container Apps' managed OpenTelemetry agent
  • Automatically collects traces and logs from container apps
  • Routes telemetry data to Azure Application Insights
  • Configured through Container Apps Environment settings

Data Flow​

  1. Applications emit OpenTelemetry-compliant telemetry
  2. Container Apps OpenTelemetry agent collects the data
  3. Data is sent to Azure Application Insights
  4. Grafana visualizes the data through Azure Monitor data source

Implementation Details​

  • Traces and logs are configured to use Application Insights as destination
  • Uses standard OpenTelemetry instrumentation for .NET
  • Automatic correlation of distributed traces across services
  • Custom metrics and traces can be added through the OpenTelemetry SDK

Redis Dashboard​

Detailed monitoring of Redis cache performance and health:

Key Metrics​

  • Memory Usage: Total and percentage used memory
  • Operations: Commands executed, cache hits/misses
  • Keys: Total keys, expired vs evicted keys
  • Connections: Connected clients, server load
  • Performance: Cache hit ratio, command processing rate

Usage​

  • Select subscription, environment, and Redis resource
  • Default view: Last 24 hours
  • Refresh interval: 30 seconds

Container Apps Dashboard​

Monitoring of Azure Container Apps deployments and performance:

Key Metrics​

  • System Logs: Container app system events and logs
  • Application Logs: Service-specific application traces
  • Deployment Status: Revision tracking and deployment logs

Usage​

  • Filter by service name and revision
  • View logs by deployment or system events
  • Track service-specific metrics and traces

Application Gateway Dashboard​

Comprehensive monitoring of Azure Application Gateway performance and WAF metrics:

Key Metrics​

  • System Health

    • Compute Units and Capacity Units
    • Healthy Host Count
    • Current Connections
    • TLS Protocol Distribution

  • Performance

    • Request Throughput
    • Network Transfer (Bytes Sent/Received)
    • Response Times (Total, Backend Connect, First/Last Byte)
    • New Connections per Second

  • WAF Security

    • WAF Log Analysis
    • Blocked Request Statistics
    • Rule Violation Distribution
    • Detailed Block List with Client IPs

Usage​

  • Select subscription and environment (test, yt01, staging, prod)
  • Monitor real-time metrics with auto-refresh (1 minute default)
  • View historical data with customizable time ranges
  • Analyze WAF security events and blocked requests

Dashboard Features​

  • Real-time performance monitoring
  • Security threat visualization
  • Network traffic analysis
  • Response time breakdown
  • Resource utilization tracking

Access​

The Application Gateway dashboard is available in the same Grafana instance at Grafana Altinn Cloud.
