Pino

Overview

Pino is a fast, lightweight logging package for Node.js applications. Known for its minimal overhead and focus on performance, Pino is designed to efficiently generate structured logs in JSON format.

Use Cases

• Send your Pino logs to Dash0 for storage and analytics.
• Understand errors.
• Correlate logs to traces to gain valuable context.

Configuring Pino

Pino produces JSON log records by default. To get the most out of Pino, we recommend the following:

1. Model log levels as string labels instead of numbers. The Pino numbers do not follow any standard and cannot be generically interpreted as errors, warnings, etc. Turning the numbers into labels improves readability for humans and machines alike.
2. If you don't yet have a log export mechanism in place, we recommend using Pino's OpenTelemetry transport. No further configuration is necessary if you followed our Node.js auto-instrumentation guidelines.
