Summary
Migrates the HyperDX API and related services from Winston to Pino for standardized,
faster, and more structured logging with improved OpenTelemetry integration.
Changes
Core Migration
- Replaced Winston with Pino across all logging infrastructure
- Upgraded @hyperdx/node-opentelemetry from v0.8.2 to v0.9.0 to support Pino
transport
- Removed deprecated dependencies:
- winston and express-winston
- @opentelemetry/host-metrics and @opentelemetry/sdk-metrics (consolidated into
newer OTel SDK)
- Added new dependencies:
- pino and pino-http for core logging
- pino-pretty for development console output
Logger Configuration (packages/api/src/utils/logger.ts)
Production:
- Outputs stringified JSON to stdout via pino/file transport
- Maintains HyperDX transport integration when API key is configured
- Includes full OpenTelemetry trace context (trace_id, span_id, trace_flags)

Development:
- Uses pino-pretty for human-readable, colorized console output
- Hides verbose fields from console: pid, hostname, trace_id, span_id, trace_flags
- HTTP request/response objects excluded from logs via custom serializers

HTTP Logging:
- Replaced express-winston with pino-http
- Custom log levels based on HTTP status codes (warn for 4xx, error for 5xx+)
- Simplified log messages: HTTP {method} {url}
Error Logging Updates
Updated error logging patterns throughout the codebase to follow Pino's structured
logging conventions:
// Before (Winston)
logger.error('Error message:', error);
// After (Pino)
logger.error({ err: error }, 'Error message');
