Pervaxis.Core.Observability

Structured logging (Serilog), distributed tracing (OpenTelemetry / AWS X-Ray), and per-request context propagation. Implements Sections 16 and 21 of the Pervaxis Platform Spec.

Installation

dotnet add package Pervaxis.Core.Observability

Registration

// In Program.cs
builder.Host.UsePervaxisLogging(sinks =>
{
    // Add CloudWatch or any other Serilog sink here
    // sinks.WriteTo.AmazonCloudWatch(...);
});

builder.Services.AddPervaxisObservability();

Configuration via appsettings.json:

{
  "Pervaxis": {
    "Observability": {
      "ServiceName": "order-service",
      "Environment": "production",
      "ServiceVersion": "1.2.0",
      "Logging": {
        "MinimumLevel": "Information"
      },
      "Tracing": {
        "OtlpEndpoint": "http://localhost:4317",
        "SamplingRatio": 1.0
      }
    }
  }
}

Per-Request Context

Set correlation, tenant, and user context at the request boundary (e.g. middleware):

public class PervaxisContextMiddleware(
    IObservabilityContextAccessor contextAccessor,
    RequestDelegate next)
{
    public async Task InvokeAsync(HttpContext httpContext)
    {
        contextAccessor.Properties = new ObservabilityProperties
        {
            CorrelationId = httpContext.Request.Headers["X-Correlation-ID"].FirstOrDefault()
                            ?? Guid.NewGuid().ToString(),
            TenantId = httpContext.Request.Headers["X-Tenant-ID"].FirstOrDefault()
        };

        await next(httpContext);
    }
}

Required Log Fields (Section 21)

Every log event is automatically stamped with:

Field	Source
`timestamp`	Serilog UTC
`level`	Serilog level
`serviceName`	`ObservabilityOptions.ServiceName`
`environment`	`ObservabilityOptions.Environment`
`traceId`	`Activity.Current.TraceId`
`spanId`	`Activity.Current.SpanId`
`correlationId`	`IObservabilityContextAccessor.Properties.CorrelationId`
`tenantId`	`IObservabilityContextAccessor.Properties.TenantId`
`userId`	`IObservabilityContextAccessor.Properties.UserId` (omitted if null)
`exceptionId`	`IObservabilityContextAccessor.Properties.ExceptionId` (omitted if null)

Sensitive Data Redaction

The RedactionDestructuringPolicy automatically redacts 22 sensitive property names: password, token, secret, apiKey, ssn, cvv, authorization, and others. Any object whose type name contains Credential, Secret, Token, or Password is fully redacted.

Distributed Tracing

using var activity = PervaxisActivitySource.StartActivity("ProcessOrder");
activity?.SetTag("orderId", orderId);
activity?.SetTag("tenantId", tenantId.Value);

Traces export via OTLP to AWS ADOT Collector → AWS X-Ray.
