About Sending Logs

Overview

Dash0 can receive logs from a variety of sources. Logs are ingested as OpenTelemetry log records and can be explored, filtered, and analyzed once they arrive.

The following guides cover specific ways to send logs to Dash0:

• Send Vercel Logs to Dash0. Covers forwarding logs from Vercel projects to Dash0 via the Dash0 Vercel integration or by configuring Vercel log drains manually.

• Send Pino Logs to Dash0. Covers best practices for getting the most out of Pino, a popular Node.js logger, including log level modeling and exporting logs via Pino's OpenTelemetry transport.

In general, any log source that can export via the OpenTelemetry Protocol (OTLP) can send data to Dash0.
