Monitoring

Overview Dashboard

Dialogporten'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, Web APIs)
  • Infrastructure: PostgreSQL, Redis, Service Bus status

Usage

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

Telemetry Collection

Dialogporten 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

Service Bus Dashboard

Azure Service Bus monitoring for message processing:

Key Metrics

  • Queue/Topic Health: Message counts, processing rates
  • Resource Usage: Namespace metrics
  • Performance: Throughput, latency, request rates

Usage

  • Select namespace and queue/topic
  • Monitor message processing status
  • Track service bus resource utilization

PostgreSQL Dashboard

Azure Database for PostgreSQL Flexible Server monitoring:

Key Metrics

  • Server Health: CPU, memory, IOPS
  • Database Performance: Connections, throughput
  • Storage: Usage and performance metrics
  • Latency: Query response times

Usage

  • Select server instance and database
  • Monitor resource utilization
  • Track query performance and connections
