What it is and what it does

SeqLog is a Python logging handler that forwards log records to Seq, a structured event server. It integrates with Python's standard logging module and extends it with support for named format arguments—allowing you to log messages with structured properties that are sent to Seq for centralized analysis.

The package depends on python_dateutil, requests, and PyYAML to handle date parsing, HTTP submission to the Seq server, and YAML-based configuration files. It supports configuration via code, YAML files, or dictionaries, and allows you to attach global properties to all log entries. Recent versions added support for the CLEF submission format and improved error handling when the Seq server is unavailable.

Use it for:

  • Forward application logs to a centralized Seq instance for real-time monitoring and historical analysis.
  • Add structured properties to log records that are automatically sent alongside messages to Seq.
  • Configure logging from YAML files to separate log setup from application code.
  • Catch and log exceptions with full stack traces and context properties to Seq for debugging.
  • Implement global log properties that are automatically attached to every log entry across your application.

Worth the install?

AI-flagged interpretation of the facts on this page — verify before relying

SeqLog sends Python log records to Seq, a centralized structured logging server, and adds support for named format arguments in log messages.

Yes, if you are already using Seq and need to integrate Python logging into it. The package is stable, has no known vulnerabilities, and low install friction. However, the aging maintenance status (last release 353 days ago) means you should verify that it meets your Python version and feature requirements before adopting it in new projects. Most suitable for teams already committed to the Seq ecosystem.

Installing seqlog

Before you install

Low install friction with a pure-Python wheel. Maintenance status is aging—the last release was 353 days ago, though the repository remains active with recent commits and no archived status.

License in practice

MIT license is permissive and imposes no restrictions on use, modification, or distribution in commercial or private projects.

Quickstart

pip install seqlog

import seqlog
seqlog.log_to_seq()

import logging
logger = logging.getLogger(__name__)
logger.info("Event with {named_arg}", named_arg="value")

Requires a running Seq server instance to be configured; the package will not fail if the server is unavailable but will silently suppress errors by default.

Verify before relying

  • Whether the package works with Python versions newer than 3.11 (classifiers list only up to 3.11).
  • Current state of the CLEF submission format support added in 0.4.0 and whether it is production-ready.
  • Whether the aging maintenance status indicates the package is still suitable for new projects or primarily maintained for existing users.
