Server Observability

Structured server logging helpers for Nest/Node runtimes.

Install​

npm install @omgjs/labkit-server-observability

Runtime: server only. Package format: CommonJS.

Public API Groups​

  • logStructuredEvent.
  • StructuredLogger, StructuredLogLevel, and StructuredLogDetails.
  • isVerbosePubSubLoggingEnabled.
  • isGraphqlSubscriptionLoggingEnabled.

Owns​

This package owns a safe JSON event envelope and error detail serialization. It also owns two generic verbose logging flags used by server runtime helpers.

App Still Owns​

The app owns event names, log transport, tracing, metrics, alerting, retention, and sensitive-data policy outside the event envelope.

Minimal Usage​

import { Logger } from "@nestjs/common";
import { logStructuredEvent } from "@omgjs/labkit-server-observability";

const logger = new Logger("Bootstrap");

logStructuredEvent(logger, "log", "app_bootstrap_configured", {
  host: "0.0.0.0",
  port: 3000,
});

Runtime Notes​

logStructuredEvent writes one JSON string through the supplied Nest-like logger. Error objects are converted into name, message, code, and stack fields when available.
