HTTP request latency — ConnectSoft.Extensions.Telemetry

ConnectSoft Company

HTTP request latency — `ConnectSoft.Extensions.Telemetry`¶

ConnectSoft.Extensions.Telemetry (NuGet 1.0.0, pinned in ConnectSoft.BaseTemplate Directory.Packages.props) exports HTTP request LatencyData produced by Microsoft.AspNetCore.Diagnostics.Middleware.

What it does¶

Structured logging summarizing checkpoints and durations
System.Diagnostics.Metrics histograms (OpenTelemetry-compatible when your host registers meter listeners / exporters)
Optional Activity tags for trace correlation
Cardinality guardrails via ConnectSoftLatencyTelemetry (MetricDimensionAllowlist, collapse label)

Wiring (templates)¶

Hosts use MicroserviceRegistrationBase (see base-template) AddMicroserviceLatencyTelemetryCollection(IConfiguration) and UseMicroserviceLatencyTelemetryCollection(), delegating to AddConnectSoftRequestLatencyTelemetry / UseConnectSoftRequestLatencyTelemetry.

Configuration¶

Section ConnectSoftLatencyTelemetry in appsettings*.json (Application, Acceptance overlays, UnitTests where strict options binding runs). Unknown keys cause startup failures.
