Fluens.Web.Observability

ASP.NET Core observability features: Prometheus metrics endpoint and request logging middleware.

Installation

dotnet add package Fluens.Web.Observability

Usage

fluensBuilder
    .AddObservability()
    .AddPrometheusExporter();

app.UseRequestLogging();        // Logs: HTTP {Method} {Path} responded {StatusCode} in {Elapsed}ms
app.UsePrometheusEndpoint();    // Maps /metrics endpoint

AddPrometheusExporter() requires AddObservability() (from Fluens.Observability) to have been called first — it attaches to the OpenTelemetry meter provider AddObservability() sets up. Calling it before AddObservability() throws InvalidOperationException naming AddObservability() as the required call. Once AddObservability() has run, AddPrometheusExporter() still silently registers nothing when ObservabilityOptions.Enabled or EnableMetrics is false.

UseRequestLogging() and UsePrometheusEndpoint() probe the marker singleton AddObservability() registers on its enabled path instead of re-reading configuration. This makes both a no-op - no middleware added, no /metrics route mapped - when observability was disabled through a callback or config, or when AddObservability() was never called at all; either way the host starts cleanly. When AddObservability() did run and is enabled, each extension additionally honours its own sub-flag (EnableLogging / EnableMetrics).
