📄 Description

Summary

  • Adds support for structured JSON log output by setting OLLAMA_LOG_FORMAT=json
  • Uses Go's standard slog.JSONHandler for the JSON format
  • Registers OLLAMA_LOG_FORMAT in the environment variable display (ollama serve startup output)
  • Default behavior (text format) is unchanged

Usage

OLLAMA_LOG_FORMAT=json ollama serve

Example JSON output

{"time":"2026-02-27T10:00:00.000Z","level":"INFO","source":{"function":"...","file":"routes.go","line":1663},"msg":"server config","env":{...}}

This enables integration with structured log aggregation systems like ELK, Splunk, Grafana Loki, or any system that consumes JSON logs.

Fixes #14018
