Netvision.Core.Observability

OpenTelemetry bootstrap for Netvision services. Registers logging, tracing, metrics, and the Prometheus scraping endpoint.

builder.Services.AddNetvisionObservability(builder.Configuration, builder.Environment);

var app = builder.Build();
app.UseNetvisionObservability();

Gateway calls AddNetvisionObservability(..., ignoreInboundTraceContext: true).

Service name resolution order: OTEL_SERVICE_NAME, Observability:ServiceName, entry assembly/application name. Common host suffixes .Web, .Host, and .Service are removed.

Netvision.Core.Metrics exposes Prometheus metrics on /metrics. Configure Metrics:PrometheusEndpoint to change it. When Metrics:Enabled is absent, metrics are enabled in Development and disabled in other environments.

Tracing configuration remains in the Tracing section. Netvision.Core.Tracing remains available for manual spans and TraceAsync.

Services with EF Core and Npgsql add Netvision.Core.Observability.EFCore and register:

builder.Services.AddNpgsqlObservability(builder.Configuration, builder.Environment);

Hangfire services add Netvision.Core.Observability.Hangfire before their existing Hangfire registration:

services.AddHangfireObservability(builder.Configuration, builder.Environment);
services.AddHangfire(configuration => configuration);

Netvision.Core.Observability.EFCore combines Tracing.EFCore and Metrics.EFCore. EF Core and Npgsql metrics are collected from the Microsoft.EntityFrameworkCore and Npgsql meters. Netvision.Core.Observability.Hangfire combines the corresponding tracing and metrics packages; Metrics:Hangfire:RecordQueueLatency=true also records pending queue time and costs one storage query per job execution.
