CasCap.Common.OpenTelemetry

Reusable OpenTelemetry configuration with standard metrics, traces, and log exporters via OTLP gRPC, built on top of CasCap.Common.Abstractions and CasCap.Common.Logging.Serilog.

Installation

dotnet add package CasCap.Common.OpenTelemetry

Purpose

Provides a single InitializeOpenTelemetry extension method on WebApplicationBuilder that registers the full OpenTelemetry pipeline (metrics, traces, and logs) with standard ASP.NET Core instrumentations. Configuration is driven by IMetricsConfig — the OTLP endpoint, service name, and metric prefix are all sourced from the application's configuration record.

Target frameworks: net8.0, net9.0, net10.0

Extensions

Extension Description
OpenTelemetryExtensions.InitializeOpenTelemetry(builder, metricsConfig, connectionMultiplexer, gitMetadata, configureMetrics?, configureTracing?) Registers OpenTelemetry metrics, traces, and logs with OTLP gRPC export

Behaviour

  • Skips registration when IMetricsConfig.OtlpExporterEndpoint is null — safe for development without an OTEL collector.
  • Development mode: Registers a Prometheus exporter for local /metrics scraping.
  • Production mode: Adds ASP.NET Core, runtime, and process instrumentations for metrics; ASP.NET Core, HTTP client, and Redis instrumentations for traces.
  • App-specific hooks: Optional Action<MeterProviderBuilder> and Action<TracerProviderBuilder> callbacks for custom histogram views, additional trace sources, etc.

Configuration

The extension reads configuration from any IMetricsConfig implementation:

Property Type Description
MetricNamePrefix string Meter name and metric prefix (e.g. "haus", "cas")
OtelServiceName string OpenTelemetry service name resource attribute
OtlpExporterEndpoint Uri? OTLP gRPC endpoint (e.g. http://localhost:4317/). null disables telemetry.

Configuration Examples

Minimal (disables telemetry):

{
  "AppConfig": {
    "MetricNamePrefix": "haus",
    "OtelServiceName": "CasCap.App"
  }
}

Fully configured:

{
  "AppConfig": {
    "MetricNamePrefix": "haus",
    "OtelServiceName": "CasCap.App",
    "OtlpExporterEndpoint": "http://opentelemetry-collector.monitoring.svc:4317"
  }
}
