Part of: Pams

NuGet package dependency

Serilog.Sinks.Seq is a NuGet dependency for the Pams API that sends Serilog log events to a Seq server. It connects application logging configuration to Seq ingestion endpoints for centralized event storage and querying.

Usage

ts
const seqUrl = "https://seq.example.com/api/events/raw";
const apiKey = process.env.SEQ_API_KEY;

const logEvent = {
  "@t": new Date().toISOString(),
  "@l": "Information",
  "@mt": "Pams API request completed",
  RequestPath: "/api/patients",
  StatusCode: 200
};

await fetch(seqUrl, {
  method: "POST",
  headers: {
    "Content-Type": "application/vnd.serilog.clef",
    "X-Seq-ApiKey": apiKey ?? ""
  },
  body: `${JSON.stringify(logEvent)}\n`
});

AI Coding Instructions

• Configure Serilog.Sinks.Seq in the Pams API logging pipeline rather than posting log events manually from application code.
• Keep the Seq server URL and API key in configuration or environment variables, not source code.
• Include structured properties such as request paths, status codes, user identifiers, and correlation identifiers in log events.
• Use Seq ingestion failures as logging diagnostics; do not allow logging transport failures to interrupt API request handling.
